Direct liquefaction of wood by catalyst (Part 2) effects of variety of wood on yields and properties of heavy oils

Abstract

In order to test the applicability of direct liquefaction in aqueous phase to various kinds of biomass, eleven varieties of woods, three varieties of wood barks, and sugar cane bagasse were studied. As a result, heavy oils having heating values from 22.7 to 26.7 MJ/kg were obtained in about 50% yield irrespective of the varieties of woods used; however, yields from wood barks were lower than those from woods due to repolymerization of the primary oils. Sugar cane bagasse could be liquefied under the same conditions as those used in wood liquefaction. © 1986, The Japan Petroleum Institute. All rights reserved.
