(621f) Feedstock Impact on Hydrothermal Liquification (HTL)

Enough sewage sludge, food waste, Fats Oils and Grease, and manure are generated every year to produce over 5.5 billion gallons of fuel per year via hydrothermal liquefaction. Waste feedstock type and composition plays a significant role not just in the hydrothermal liquefaction (HTL) process but also in upgrading HTL biocrudes to fuels via hydrotreating. This presentation will compare the hydrothermal liquification and catalytic hydrotreating for a variety of wet waste feedstocks, including sewage sludge, pig manure, dairy manure, biosolids, and other feedstocks, to ultimately produce fuel blendstocks.
