<p>1390356 Ketonic oil JOHNSON MATTHEY & CO Ltd 8 March 1972 [9 March 1971] 6341/71 Heading C2C A ketonic oil, usable as a fuel oil, is made by treating a cellulosic waste material with a reducing gas in the presence of a catalyst containing Cu, Ru, Rh, Pd, Ir, Os and/or Pt. The cellulosic material can be newsprint, sugar cane or sugar beet pulp, animal manure, wood pulp, waste corn or waste vegetable products, or waste from food processing. The reducing gas can be hydrogen, carbon monoxide, methane or a mixture containing one or more of these. The reaction can be carried out at 100-950‹ C. and 150-10,000 psi. A suitable catalyst is ruthenium in the form of the metal, an alloy, ruthenium dioxide or an alkaline solution of sodium ruthenate. The catalyst residue can be recovered from the residue of the cellulosic material. The I.R. spectrum of the oils shows the presence of hydroxyl, aliphatic C-H, acidic C = O and ketonic C = O groups.</p> |
