Method and apparatus for enzymatic hydrolysis, liquid fraction and solid fraction

摘要

Problem to be solved: to provide a method for enzymatic hydrolysis in which the plant material is hydrolyzed by an enzyme.A method for enzymatic hydrolysis of plant based raw materials at least two enzymatic hydrolysis stages;Plant raw materialLigninCelluloseContains hemicellulosePlant raw materialHydrolyzed at the initial enzymatic hydrolysis stageThe residence time at the initial enzymatic hydrolysis step is over 8 hours.AndLess than 12 hours;After the initial hydrolysis stageThe liquid fraction containing carbohydrate isSeparated from solid fraction at solid-liquid separation stageThe solid fraction is hydrolyzed at the following enzymatic hydrolysis stepsThe residence time at the second or subsequent hydrolysis stage exceeds 24 hoursAfter any second and subsequent hydrolysis stepsThe liquid fraction containing carbohydrate isSeparated from solid fraction at solid-liquid separation stageAnd the solid fraction is recovered after the last solid-liquid separation stage;Method.No selection
