Methods for conversion of a glycol reaction product obtained from hydrothermal digestion of cellulosic biomass solids into a dried monohydric alcohol feed

用于将由纤维素生物质固体的水热消解获得的二醇反应产物转化为经干燥的一元醇进料的方法

Abstract

Hydrothermal digestion of cellulosic biomass solids may produce a glycol reaction product for subsequent processing. Methods for digesting cellulosic biomass solids to form and process a glycol reaction product may comprise: providing cellulosic biomass solids and a slurry catalyst in a hydrothermal digestion unit, the slurry catalyst being capable of activating molecular hydrogen; heating the cellulosic biomass solids in the hydrothermal digestion unit in the presence of the slurry catalyst, a digestion solvent, and molecular hydrogen, thereby forming a liquor phase comprising soluble carbohydrates; performing a first catalytic reduction reaction on the soluble carbohydrates within the hydrothermal digestion unit, thereby at least partially converting the soluble carbohydrates into a reaction product comprising a glycol; at least partially drying the reaction product, thereby forming a dried reaction product comprising a dried glycol; and at least partially converting the dried glycol into a monohydric alcohol external to the hydrothermal digestion unit.
纤维素生物质固体的水热消解可产生二醇反应产物以用于随后的加工。用于消解纤维素生物质固体以形成并加工二醇反应产物的方法可包括:在水热消解单元中提供纤维素生物质固体和浆料催化剂,所述浆料催化剂能够活化分子氢;在所述浆料催化剂、消解溶剂和分子氢的存在下在水热消解单元中加热所述纤维素生物质固体,由此形成包含可溶性碳水化合物的液相;在水热消解单元内对所述可溶性碳水化合物进行第一催化还原反应,由此将所述可溶性碳水化合物至少部分转化为包含二醇的反应产物;至少部分干燥所述反应产物,由此形成包含经干燥的二醇的经干燥的反应产物;以及在水热消解单元外部将所述经干燥的二醇至少部分转化为一元醇。
