Abstract

There have been a number of investigations using liquefaction pretreatment which show how liquefaction yields increase following pretreatment. The mechanisms for this are largely unknown but are believed to be connected with increased mass-transfer rates of hydrogen donors which help to limit regressive cross linking reactions. This study only deals with systems that show an increase in liquid products.
