A method for producing fuel oil from cellulosic materials (especially domestic or agricultural waste) in which the material is contacted with water and treated with a reducing gas (eg hydrogen or methane) and carbon monoxide in the presence of a platinum group metal (preferably ruthenium) or copper catalyst at 100.degree. to 950.degree. C. (preferably 100.degree. to 250.degree. C.) and at 10 to 680 (preferably 10 to 100) atmospheres. It is believed that the cellulose is hydrolyzed, then carbonylated to a keto acid which decarboxylates to produce a polymerizable acid and carbon dioxide. The aldehyde polymerizes and is hydrogenated to produce the fuel oil.
A method for producing fuel oil from cellulosic material which comprises contacting the cellulosic material with liquid water and treating contacted material with a reducing gas which contains carbon monoxide in the presence of a catalyst comprising at least one metal, alloy of a metal and/or compound of a metal wherein the metal is selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum and copper and at an initial temperature of from 100.degree. C. to 950.degree. C. and an initial pressure of from 10 to 680 atmospheres.

A method for producing fuel oil from cellulosic material which comprises contacting the cellulosic material with water and treating the contacted material with a reducing gas and carbon monoxide in the presence of a catalyst comprising at least one metal, alloy of a metal and/or compound of a metal wherein the metal is selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum and copper under conditions of temperature and pressure such that at least some of the water is liquid and at a temperature of at least 100.degree. C. and a pressure of at least 10 atmospheres.
