The Hydrofaction® process has now successfully produced biocrude from many substantially different biowaste feedstocks. Woody biomass waste, agricultural plant waste, animal waste, and the biogenic portion of municipal solid waste (MSW) streams appear presently to have the properties handled readily by Hydrofaction® and produce biocrude of high quality. Biocrude from these sources also has known Upgrading pathways. Evidence is clear however, Hydrofaction® is capable of converting many other feedstocks as well. Untested feedstocks will have varied properties that can impact both the Hydrofaction® and Upgrading processes. Steeper Energy’s Pilot Plant, Demo Plant and its Advanced Biofuels Center contribute to testing to better understand the handling and processing customization that might be required to confirm the viability of a new biowaste stream for Hydrofaction®.
Steeper has from the beginning been focused on woody biomass as the most promising candidate for Hydrofaction® processing driven by the following factors:
Other biomass sources well suited to being converted into Hydrofaction® Oil include agricultural crop residues and farming/animal wastes. Agricultural crop residues include corn stover, sugarcane bagasse, wheat straws, rice husks and rice straw. Farming/animal wastes incorporate bedding straw which can also be mixed with animal manure and processed with Hydrofaction®
While all components of lignocellulosic waste streams are readily handled by Hydrofaction®, non-lignocellulosic waste streams such as the biogenic portion of MSW can also be converted into Hydrofaction® Oil.
