219. ------. [BRAUNKOHLE-BENZIN, A. G.] [Catalytic Cracking] German Patent Appl. B 181,885, no date (Cl. IV d-23 b). PB Rept. 412, May 15, 1945.

Cracking heavy hydrocarbons over catalysts that serve at lower temperatures for the synthesis of hydrocarbons from CO and H₂. Such a catalyst, which is spent for synthesis, can be used for cracking. The oil to be cracked may be vaporized or atomized with H₂. A cracking temperature of 300º-350º C is suggested.
