Retrogressive Reaction of Coal Liquefaction

Abstract

The object of this paper is to reduce production of residue discharged from coal liquefaction. Some kinds of residue, for example difference of reaction temperature, have been examined for their boiling point distribution. From these results, the process of retrogressive products is estimated.
In addition, to make sure the mechanism of retrogressive reaction on coal liquefaction, the corresponding raw coal was reacted at various conditions.
