Wood liquefaction--An overview

Abstract

During the past decade, numerous papers on wood liquefaction have been published, covering fundamental aspects through to potential processes. After introducing the characteristics of wood, the physico-chemical aspects of wood liquefaction are examined. A large part of the paper is devoted to liquefaction processes: first-generation processes (direct liquefaction), pretreatment processes, usually based on mechano-chemical treatment of lignocellulosic material, and second-generation processes (solvolysis processes).
