Reaction mechanisms of hydrothermal liquefaction of model compounds and biowaste feedstocks

, 2011
It has been demonstrated that hydrothermal liquefaction (HTL) could be an efficient technology that can not only reduce COD and pollutants in the bio-wastes but also generate valuable renewable bio-crude oil from many biomass sources.
