发明名称 BIOMASS TREATMENT FOR HYDROTHERMAL HYDROCATALYTIC CONVERSION
摘要 A selective removal of chlorine and phosphorus that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed prior to carrying out catalytic hydrogenation/hydrogenolysis/hydrodeoxygenation of the biomass in a manner that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided

主权项 1. A method for selective removal of chlorine and phosphorus from a cellulosic biomass solids comprising: a. providing a detrimental species-containing cellulosic biomass solids; b. introducing said detrimental species-containing cellulosic biomass solids from an inlet into a treatment vessel, said cellulosic biomass solids having a true interstitial volume in said vessel; c. introducing a base solution having a pH of greater than 9 from an inlet to said cellulosic biomass solids containing vessel at a temperature in the range of 0° C. to 60° C. in an amount to fill at least about 5% bed volume to at most about 40% bed volume of said true interstitial volume; d. subsequently to step c, introducing an aqueous solution having a pH of at most 8 from an inlet to said basic cellulosic biomass solids-containing vessel, thereby producing washed cellulosic biomass solids having reduced detrimental species content compared to the detrimental species-containing cellulosic biomass solids and a basic water effluent, wherein said basic water effluent is in the range of about 3 parts to about 0.5 parts relative to about 1 part of detrimental species-containing cellulosic biomass solids (dry basis); e. introducing a removal stream comprising a gas stream or an organic solvent solution from an inlet to the vessel containing the washed cellulosic biomass solids thereby producing a pretreated cellulosic biomass solids with reduced water content compared to the water washed cellulosic biomass solids and an aqueous effluent; f. discharging the pretreated cellulosic biomass solids from an outlet and transferring at least a portion of the discharged pretreated biomass solids to a digestion and/or reaction zone; g. recycling at least a first portion of the aqueous effluent to produce base solution; and h. recycling at least a second portion of the aqueous effluent as an aqueous solution.
