Abstract

Wood is pulped by the action of a grinding member in the presence of a liquid - conventionally water. In order that the process can be carried out above 100 DEG C, either under pressure or at atmospheric pressure, a liquid is used which has a boiling point, at atmospheric pressure, above 100 DEG C.
