Invited Session: Energy Recovery

Conversion of LFG and Biogas to Drop-in Diesel (0.5 CEU)

Monday, September 25, 2017
15:30 – 16:00
Room 320

The agricultural and landfill industries make up 29 percent of the U.S. methane emissions. Methane is considered a greenhouse gas that contributes significantly to global warming/climate change. Additionally, these two industries are heavy consumers of fossil fuels and in the U.S. alone, consumed 4.2 billion gallons of diesel fuel annually making up 6.9 percent of the total U.S. diesel consumption. None of the commercial scale waste-to-energy technologies use the CO2 portion of the biogas and simply allow the CO2 to either pass through or be separated from the CH4 and emitted to the atmosphere. This presentation introduces a new catalytic technology (TRIFTS) capable of utilizing both the CO2 and CH4 portions of biogas and incorporates them into the hydrocarbon backbone of the final product of the process (diesel). This renewable source of diesel resembles its petroleum counterpart both physically and chemically and can be used in current day engines with no engine modifications necessary. The heavy equipment and waste hauling trucks can therefore unload and refuel at the same landfill site with a renewable diesel fuel derived from the very waste they hauled. Thus a closed loop process is created from feedstock to end point user.

By attending this presentation, participants will better be able to evaluate new technology developments in the waste-to-energy sector. Participants will gain a better understanding of what future waste-to-energy projects are capable of and how they compare to current waste-to-energy technologies.

Devin Walker

Devin Walker’s background includes more than 10 years industrial experience processing hydrocarbon fuels from biomass, landfill gas, biogas, natural gas and bio oils to create commercial and military grade fuels such as gasoline, diesel, JP-8, and Navy distillate. After graduating from University of Florida with a Bachelor’s degree in biochemistry, Mr. Walker began his career as a scientist researching and designing advanced alternative fuels in the private sector. In 2012 Mr. Walker graduated from USF with his Master’s degree in chemical engineering. Mr. Walker developed a passion for energy and fuels, specifically the research involved in finding efficient, novel and feasible solutions to the world’s energy problems. He recently was recognized by Forbes Magazine as one of the top "30 under 30" in Energy and Industry for 2014. In 2016, he began working full time with T2C-Energy as the CEO. During this past year, he successfully managed and served as the principal investigator for the development of T2C-Energy’s biogas to drop-in diesel fuel project. The project successfully converted raw landfill gas to drop-in diesel fuel that met all major No.2 diesel fuel specifications per ASTM D975.
