Abstract
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.
