Patent Abstracts

CO and S-free H₂(2:1 vols.) are passed over an oxide catalyst at 1 m.3 per hr. for each 1. of catalyst at a temperature of 470º-475º and a pressure of 150 atm. The products form 2 layers, the lower being aqueous, which gives MeOH, acetone, etc., on distilling, and the upper is separated into 2 fractions. That below 115º is heated over an Al catalyst at 420º, and the resulting olefins are polymerized and then hydrogenated at 400º under 150 atm. over MoO and active C as catalysts. H₂O is removed after this treatment and the fuel added to that obtained from the first fraction.
