PROCESS FOR WASHING SOLID CELLULOSIC BIOMASS MATERIAL

摘要

A process for treating a solid cellulosic biomass material for reduction of the content of unwanted inorganic components prior to using the material in the production of a biofuel and/or biochemical, comprising: - providing a solid cellulosic biomass material; - washing the solid cellulosic biomass material with a stream of water or in a water bath, wherein the water has a temperature in the range from 120°C to equal to or less than 150°C at a pressure high enough to maintain water in the liquid phase, to provide washed cellulosic biomass material comprising significantly reduced levels of unwanted inorganic components when compared to the levels in the starting biomass material.
