Abstract
1,155,879. Purifying ethylene/ethane mixtures. BADISCHE ANILIN- & SODAFABRIK A.G. 4 Nov., 1966 [5 Nov., 1965; 24 May, 1966], No. 49523/66. Heading C5E. Mixtures of ethylene and ethane, which have been selectively catalytically hydrogenated (e.g. over a Pd catalyst) to remove small amounts of acetylene therefrom, are treated to remove polymerization products formed during the hydrogenation by passage over a layer of coke, silica gel and/or alumina gel. The treatment is preferably conducted under the same pressure as the hydrogenation. Suitable layers of coke Rc are 2-6 metres deep, and the gas mixture is usually passed upwards through the layer, oily polymers being drained continuously or periodically from the bottom of the layer.
