Abstract: 

2What is HTL and why do we care?Hydrothermal liquefaction (HTL) is...the thermochemical conversion of biomass in a hot, pressurized water environment to break downsolid biopolymer structures to predominantly liquid componentsIt stands out among thermal conversion processes because...•HTL is a conceptually simple (i.e., heated pipe), scalable, and robust continuous process that canaccept a diverse range ofwet feedstocks(no drying!)•HTL results inhigh carbon yieldsto liquid hydrocarbons (up to 60%)•HTL produces a gravity-separable biocrude with low oxygen content (5–15 %) that can beupgraded in a single stage hydrotreater
