CONTINUOUS OR SEMI-CONTINUOUS BIOMASS WASH SYSTEM FOR HYDROTHERMAL HYDROCATALYTIC CONVERSION

摘要

A selective removal of metal and its anion species that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed in a continuous or semi-continuous manner prior to carrying out catalytic hydrogenation/hydrogenolysis/ hydrodeoxygenation of the biomass that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided.
