WebHydrothermal liquefaction (HTL) is biocrude oil production using biosolids from wastewater treatment and waste biomass. It is one of the leading methods to convert complex organic feedstocks such as biosolids from wastewater treatment and other waste biomass feedstocks into valuable products like transport fuels and their precursors.
Hydrothermal liquefaction (HTL) is a thermal depolymerization process used to convert wet biomass, and other macromolecules, into crude-like oil under moderate temperature and high pressure. The crude-like oil has high energy density with a lower heating value of 33.8-36.9 MJ/kg and 5-20 wt% oxygen and renewable chemicals.
