3992. ZERBE, c. (Rhenania-osssag Mineralöwerke A. G.). [Catalyst for Cracking Hydrocarbons.] German Patent 738,752, July 29, 1943 (Cl. 23 b-1.04). Chem. Zentralb., 1944, I, p. 841; Chem. Abs., vol. 38, 1944, p. 4789.

Residues from synthesizing hydrocarbons, aldehydes, and carboxylic acids from dehydrogenation, from addition, condensation, and polymerization reactions carried out with AlCl₃are used as catalysts for the cracking processes. These residues consist predominantly of organic compounds containing Cl, inorganic compounds containing S and Cl, oxidation products and small amounts of metal chlorides.
