Process and apparatus for conversion of biomass

摘要

The invention is directed to a process for the conversion of biomass, in particular lignocellulose-containing biomass into a product that may be further processes in a fermentation step. The invention is further directed to apparatus suitable for carrying out such processes. According to the invention biomass is converted into a fermentable product by contacting in a reactor said biomass with an acid, while passing a gas stream through said reactor, by which the pH in said reactor can be controlled.
