Kolts, J H

A method is described for cracking feed hydrocarbons comprising at least one of propane and butanes to produce less saturated hydrocarbon products and selectively maximize the content of one of ethylene and propylene in the less saturated hydrocarbon products. The method comprises: (a) contacting the feed hydrocarbons with a cracking catalyst selected from the group consisting of: (1) a catalyst composition, consisting essentially of: 0.1 to 30 wt.% of (A) at least one oxide of manganese and the balance of (B) at least one oxide of magnesium; (2) a catalyst composition, consisting essentially of: 1 to 15 wt.% of (A) at least one oxide of one metal selected from the group consisting of calcium, strontium, barium, tin and antimony, 0.1 to 30 wt.% of (B) at least one oxide of manganese and the balance of (C) at least one oxide of magnesium; and (3) a catalyst composition, consisting essentially of: 1 to 15 wt.% of (A) at least one oxide of a metal selected from the group consisting of silicon, aluminum and titanium, 0.1 to 30 wt.% of (B) at least one oxide of manganese and the balance of (C) at least one oxide of magnesium.
