processes for treating a lignocellulosic material and for reducing the chloride content in a lignocellulosic material

摘要

A process for treatment of a lignocellulosic material comprising contacting the lignocellulosic material with a solution of chloride ions, which solution comprises a concentration of chloride ions in the range from equal to or more than 1 ppm weight to equal to or less than 350 ppm weight based on the total weight of the solution; at a temperature in the range from equal to or more than 120° C. to equal to or less than 200° C.; and at a pH in the range from equal to or more than 0.1 to equal to or less than 4.
