Abstract

A method for producing a partially hydrolysed lignocellulosic material is provided including treating a lignocellulosic material with an acid and/or an alkali and then a polyol. Also provided are methods of producing a fermentable sugar, or a fermentable sugar and a fermentation product from said partially hydrolysed lignocellulosic material. A partially hydrolysed lignocellulosic material, a fermentable sugar, and fermentation product produced by such methods are also provided. Also provided is an apparatus for producing a partially hydrolysed lignocellulosic material, such as by the aforementioned method.

Abstract

A reactor apparatus and reactor system for treating a lignocellulosic material is provided, said apparatus and system including a reactor which is switchable between a first mode for producing a first reaction product including a partially hydrolysed lignocellulosic material and a second mode for producing a second reaction product suitable for conversion into a cellulosic pulp. Also provided is a method of operating a reactor system for treating a lignocellulosic material, which includes selecting between first and second modes of operation of a reactor, wherein the first mode is adapted to produce a first reaction product comprising a partially hydrolysed lignocellulosic material and the second mode is adapted to produce a second reaction product suitable for conversion into a cellulosic pulp.
