Kolts, J H; Delzer, G A

A method is described for converting feed hydrocarbons comprising at least one of C/sub 3/ and C/sub 4/ hydrocarbons to less saturated hydrocarbons, comprising: contacting the feed hydrocarbons with a catalyst composition selected from the group consisting of: (a) a catalyst, consisting essentially of: about 0.1 to 30 wt. % of each of (1) at least one oxide of chromium and (2) at least one oxide of manganese and the balance of (3) at least one oxide of magnesium; (b) a catalyst, comprising: about 0.1 to 30 wt. % of each of (1) at least one oxide of chromium and (2) at least one oxide of manganese and the balance of (3) at least one oxide of at least one metal selected from the group consisting of Lanthanum Series metals and niobium; (c) a catalyst, consisting essentially of: about 0.1 to 30 wt. % of each of (1) at least one oxide of chromium, (2) at least one oxide of at least one metal selected from the group consisting of calcium, strontium, barium, tin, and antimony and (3) at least one oxide of manganese and the balance of (4) at least one oxide of magnesium; and (d) a catalyst, comprising: about 0.1 to 30 wt. % of each of (1) at least one oxide of chromium, (2) at least one oxide of at least one metal selected from the group consisting of calcium, strontium, barium, tin and antimony and (3) at least one oxide of manganese and the balance of (4) at least one oxide of at least one metal selected from the group consisting of Lanthanum Series metals and niobium, the wt. % being expressed in terms of the element based on the total weight of the catalyst, under conditions sufficient to convert the feed hydrocarbons to the less saturated product hydrocarbons.
