Title: Method for wet torrefaction of a biomass

Patent ·
OSTI ID:1568709
; ; ;

A process for increasing the energy density of a biomass, which includes establishing a temperature and pressure within a reaction chamber that includes water and is at or above a desired reaction condition wherein the desired reaction condition is sufficient to increase the energy density of a reacted biomass; introducing a biomass into the reaction chamber such that the desired reaction condition is maintained or equilibrates thereto; and subjecting the biomass to the desired reaction condition for an amount of time effective to increase the energy density of the reacted biomass relative to the biomass prior to reaction.
