Optimization, Upscaling, and Economic Feasibility of GBTL Technology
January 8th, 2018

Fast pyrolysis is a promising technology for the production of liquid fuels or bio-oil through thermal decomposition of biomass or municipal solid waste in the absence of oxygen. Bio-oil can be converted into hydrocarbons and has potential application in the transportation sector. However, converting bio-oil into usable fuels and chemicals remains a challenge. Bio-oil cannot be used directly without being upgraded because of its unwanted properties (e.g. high oxygen, acidic, and low energy). Traditional bio-oil upgrading usually involves extensive hydrotreating, which is energy intensive and costly.

ajay kumarDr. Ajay Kumar, Associate Professor of Biosystems and Agricultural Engineering at Oklahoma State University (OSU), together with two other OSU professors, Drs. Allen Apblett (Chemistry) and Francis Epplin (Agricultural Economics) demonstrated that natural Gas and Biomass to Liquids (GBTL) technology that utilized co-conversion of biomass and methane with metal-loaded HZSM-5 catalysts significantly improved aromatic hydrocarbon yield in the bio-oil.

Kumar’s team then leveraged results from their earlier GBTL study to make this novel technology ready for scale-up. The research team aimed to optimize key co-pyrolysis reaction conditions to maximize yield and selectivity of hydrocarbons and to determine production costs of liquid biofuel.

Kumar and co-workers used fixed bed and pyroprobe reactors to investigate the effects of methane, temperature, and catalyst in weight yield, energy recovery, chemical composition, and aromatic hydrocarbon yield of bio-oil from eastern red cedar and municipal solid waste.

“We achieved a maximum bio-oil yield of 53 wt% with an energy contact of 10 MJ/Kg and

56 wt% when we used methane over MoZn/HZSM-5 catalyst at 650oC and 750oC, respectively,” Kumar said. “This indicated that introduction of methane in catalytic pyrolysis of biomass improved the quality of bio-oil.”

“We also found that biochar yield increased when temperature was increased from 650oC to 750oC during pyrolysis,” Kumar added.

The research team also conducted an economic analysis that focused primarily on the availability and cost of eastern redcedar biomass that can be delivered to a biorefinery. A mixed integer programming was used to determine the optimal location for an eastern red cedar processing plant. The model produced solutions for several combinations of annual feedstock requirements, proportion of existing redcedar biomass in a county available for harvest, growth rate of unharvested trees, harvest cost transportation cost, and discount rate.

“In order to support a biomass processing facility with a capacity of 500 Mg/day of eastern red cedar, between 18% and 24% of the available eastern redcedar would need to be contracted for harvest over a 20-year period, with the difference in contracted percentage depending on the annual growth of redcedar,” Epplin said.

“The estimated cost to deliver eastern red cedar to the factory ranged from $44/Mg to $58/Mg depending on the proposition of eastern red cedar biomass under contract as well as the quantity of biomass required per day,” Epplin said.

Funding of this project was provided by the U.S. Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) through the South Central Sun Grant Program.

GBTL Technology for Liquid Hydrocarbon Production
March 1st, 2017

To supplement the demands of petroleum fuels and chemicals using existing infrastructure of engines, pipeline and fuel delivery, it is logical to target producing compatible hydrocarbons from biomass resources. Bio-oil produced from biomass fast pyrolysis technology can be converted into hydrocarbons. However, this conversion process remains a major challenge due to the instability of bio-oil, making it challenging to store, transport and convert into useful fuels and chemicals. In addition, high oxygen content in bio-oil makes it very unstable. Oxygen must be removed and additional hydrogen must be added to maximize hydrocarbon production.

ajay kumarTraditional bio-oil upgrading usually involves extensive hydrotreating, which is energy intensive and costly. Hence, Dr. Ajay Kumar, Associate Professor of Biosystems and Agricultural Engineering (BAE), Oklahoma State University (OSU), collaborated with another OSU Professor, Dr. Allen Apblett from Chemistry, to demonstrate proof-of-concept of a novel natural Gas and Biomass to Liquids (GBTL) technology that will synergistically use biomass (e.g. switchgrass and eastern red cedar) and methane to produce liquid hydrocarbons that are compatible with existing infrastructure. Kumar’s research team used a synergistic reaction system consisting of activation of methane and deoxygenation of pyrolysis-derived volatiles with metal-loaded HZSM-5 catalysts.

“We found that methane GBTL-Kumarsignificantly improved the yield and selectivity for the formation of aromatic hydrocarbons in the bio-oil obtained from catalytic pyrolysis of biomass,” Kumar said. “Methane did not show effective improvement in the yield of aromatic hydrocarbons from cellulose and hemicellulose in the presence of molybdenum modified HZSM-5 catalysts, but significantly improved the aromatic hydrocarbons from lignin,” Kumar added.

Torrefaction pretreatment on switchgrass did not increase the aromatic hydrocarbon yield. “Torrefaction infavorably altered the biomass composition by reducing cellulose content while increasing lignin content. The aromatic hydrocarbon yield decreased as the torrefaction temperature increased from 230 to 270 oC,” Kumar said.

This project shows that direct co-conversion of biomass and methane with an appropriately designed catalyst leads to significant improvements in hydrocarbon yields. Kumar said, “the direct conversion of biomass pyrolysis volatiles and methane in a catalytic reactor is a unique approach that makes it possible to produce hydrocarbon fuels more efficiently than traditional pyrolysis-based refinery processes.”

Demonstration of the proof-of-concept through optimization and analysis of economic feasibility is underway. Dr. Kumar collaborated with two other OSU Professors from the Department of Agricultural Economics, Drs. Francis Epplin and Phil Kenkel, for this part of the study. Funding of this project was provided by the U.S. Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) through the South Central Sun Grant Program.

USDA-NIFA Supports Two Projects from Texas A&M University through the South Central Sun Grant Program
February 1st, 2017

Dr. Girisha Ganjegunte, Associate Professor, Texas A&M Agrilife Research at El Paso, Texas, and Dr. Bruce McCarl of Texas A&M University, College Station, TX, are the recipients of USDA-NIFA research grants through the South Central Sun Grant Program’s regional competitive grants program.

ganjegunteGirishaDr. Ganjegunte collaborates with Drs. Yanqi Wu (Oklahoma State University), April Ulery (New Mexico State University), Samuel Zapata (Texas A&M Agrilife Extension Service), Genhua Niu and Juan Enciso (Texas A&M Agrilife Research) to conduct a study on “Developing Alternative Water Sources for Bioenergy Crops Production on Marginal Lands”. This study aims to evaluate the effects of marginal quality water irrigation on the performance of switchgrass, biomass sorghum, and canola as well as on irrigation use efficiency and salinity.

Another grant awarded will model McCarl-Band analyze the logistics of supplying biomass for biofuel and biopower. This project is led by Dr. McCarl in collaboration with Drs. Stephen Searcy and Neil Geismar (Texas A&M University) and Dr. Jeffrey Vitale (Oklahoma State University). McCarl’s team aims to develop methods to improve efficiency of biomass supply chains with the goal of reducing final product cost by 15 % to make industries and bioenergy market penetration more viable.

Soil Health Remediation Potential Using Bioenergy Crops: Miscanthus and Switchgrass
January 25th, 2017

Degraded soils that are economically marginal and environmentally vulnerable are unsustainable with the current cropping systems. To attain sustainable production on marginal soils, new cropping systems that minimize long-term economic and environmental risks are needed to restore soil health and sustainability of these soils.

newell kitchenDr. Newell Kitchen, Soil Scientist of USDA-ARS, Columbia, Missouri, teamed up with coworkers at USDA-ARS: Drs. Ken Sudduth, Bob Kremer, Matt Yost, and Kristen Veum; Drs. Allen Thompson, Stephen Anderson, Ray Massey, and Brenton Myers (now with DuPont Pioneer) of University of Missouri; and Dr. Emily Heaton from Iowa State University to determine soil health remediation and production potential when growing miscanthus and switchgrass on marginal claypan soil.

Kitchen’s research team SPARC Plotsutilized the already-established Soil Productivity Assessment for Renewable Energy and Conservation (SPARC) plots near Columbia, MO (See photo) for this project.

Kitchen’s group found that miscanthus rhizomes planted on eroded soils performed well. On eroded claypan soils, only about 30% of the time required N fertilizer to maximize Miscanthus yield.  Relative leaf chlorophyll concentration was found as an accurate indicator of fertilization need.

Switchgrass had greater water use efficiency (WUE), about 50% greater N recovery efficiency and about 50% less run-off compared to corn. In addition, soil hydraulic properties of the marginal claypan soils improved when switchgrass was grown (3% lower bulk density, 73% greater hydraulic conductivity, and 53% larger proportion of soil macro pores) compared to corn-soybean cropping system.

Kitchen’s group also determined that switchgrass planted on degraded soil with shallow topsoil had greater quasi-steady infiltration rate and field saturated hydraulic conductivity than row-crop management. “When our results were applied to 24-hour USDA NRCS Type II storm model, switchgrass enhanced estimated infiltration, reduced estimated run-off and decreased estimated water ponding time when compared to row crop management,” Kitchen said.

In terms of the production relative to the topsoil thickness of claypan soil (depth-to-claypan or DTC), net return was greater for corn and soybean over most DTC, while switchgrass was only able to compete on very shallow DTC (<5 cm). Conversely, ethanol production from switchgrass increased with greater DTC for drier than average years and with N fertilization.

“These findings will help farmers know where to grow perennial bioenergy crops instead of grain crops, especially on eroded claypan soils, in order to improve production and minimize negative environmental effects associated with perennial plant bioenergy production”, Kitchen said.

Funding of this project was provided by the U.S. Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) through the South Central Sun Grant Program.

Mushroom Pretreatment Promotes Lignin Degradation During Storage of Switchgrass
November 29th, 2016

Mark WilkinsDr. Mark Wilkins, former Professor at Biosystems and Agricultural Engineering (BAE), Oklahoma State University (OSU), collaborated with two other OSU faculty Drs. Michael Buser (BAE) and Stephen Marek (Entomology and Plant Pathology), and Dr. Julie Carrier from Biosystems Engineering and Soil Science at University of Tennessee to investigate whether oyster mushrooms, Pleurotus ostreatus, could be used to break down lignin in switchgrass in a controlled storage environment. The research team aimed to develop and optimize an integrated switchgrass storage fungal pretreatment system, which could aid in lignin degradation and reduce the severity of subsequent thermochemical pretreatment processes, which are necessary for preparing switchgrass from enzymatic hydrolysis.

Small square bales of “Kanlow” square bales set upswitchgrass were used to test the effect of fungal application on lignin degradation and sugar content during storage. Three different rates of oyster mushroom spores were applied to the switchgrass bales prior to storage in a moisture and temperature controlled laboratory. Degradation of lignin, cellulose and hemicellulose was monitored every 27 days during storage of bales with and without fungus applied.

Wilkins’ group found that the use of fungus promoted lignin degradation compared to controls in bales stored at 50% and 75% moisture content. However, significant degradation of cellulose occurred if switchgrass was stored with fungus for more than 55 to 60 days. “In order to preserve cellulose, fungal pretreatment should not continue beyond 60 days. The timing of storage is important since storing bales for more than two months resulted in significant loss of cellulose, which is the most valuable portion of the grass,” Wilkins said.  “In small bales, degradation of lignin, cellulose, and hemicellulose occurred in control bales due to microorganisms already present in the bales, but degradation of lignin and hemicellulose was less than that observed in bales to which fungus was applied,” Wilkins added.

Wilkins’ group also added copper, manganese and glucose to switchgrass along with the fungus to determine if these supplements would improve lignin degradation by P. ostreatus as other literatures suggested that these supplements would boost lignin degrading enzyme activity.

“All of the supplements added decreased lignin degradation compared to no supplementation. This result indicates that all of the nutrients needed for fungal growth are present in switchgrass, and costly supplementation is not required”, Wilkins said.

Enhanced Biofuels Production with Genetically Optimized Feedstocks using Multistage Pyrolysis
October 28th, 2016

Thermal processing of biomass is a rapid, low-cost method to produce bio-oil that can be refined to renewable transportation fuels. Major challenges in the utilization of bio-oil for producing biofuels include chemical complexity, acidity and instability. The goal of this work is to simplify biomass thermal product streams to make them more amenable to catalytic upgrading and subsequent use as fuels, optimizing carbon yields.

BartleyDr. Laura Bartley, Associate Professor of Microbiology and Plant Biology, University of Oklahoma (OU) together with Drs. Richard Mallinson and Lance Lobban (Chemical Engineering, OU) and Dr. John Mullet (Biochemistry and Biophysics, Texas A&M University) conducted a study to examine how chemically and physically altering switchgrass and sorghum biomass relates to yields of thermal products under two different temperatute regimes, torrefaction and fast pyrolysis.

This project successfully gathered detailed data on a set of compositionally diverse switchgrass samples and predicted the thermal pyrolysis products of switchgrass and sorghum collections. Bartley's Fig 1The team also distinguished among possible associations between composition and products by measuring the thermal products from selectively altered switchgrass biomass, specifically biomass that had been chemically pretreated with water, base, or enzymes and biomass that has been genetically modified to deplete S-lignin and hydroxycinnamates (HCAs) via down-regulation of the phenylpropanoid biosynthesis gene, COMT. Results showed that low S-lignin and low HCA switchgrass releases less methoxyphenols into the torrefaction product stream (Fig.1) but does not reduce overall carbon yields. These results provide new directions for improving thermochemical biofuel production by rendering the torrefaction product stream more acceptable to catalytic upgrading.

Funding of this project was provided by the U.S. Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) through the South Central Sun Grant Program.
