A process for the flameless catalytic cracking of gaseous and liquid vaporizable hydrocarbons having 2 to 30 C atoms per molecule with steam and insufficient O 2 for complete combustion, optionally with CO 2 , to produce H 2 and CO, utilizes a catalyst which has been calcined at 1300‹ to 1400‹ C., and comprises cobalt on a carrier material of MgO, optionally with Al 2 O 3 .The process allows feedstocks containing up to 1 g. of sulphur per Kg. of feed to be cracked without a pretreatment. Feeds mentioned are gasoline fractions (B.P.R. 40‹ to 160‹ C.) and gas oils (B.P.R. 65‹ to 360‹ C.), and gaseous hydrocarbons containing up to 90 vol. per cent unsaturates. The reactants are preheated, and the process may be performed at atmospheric or superatmospheric pressure. A conventional Pt catalyst may precede the CO catalyst. Details of the main catalyst are: cobalt content, 3 to 40% b.w. (preferably 5 to 25%) and ZrO 2 or an alkali metal compound may be added to the carrier, e.g. from 0À5 to 10% b.w. Two specific examples are described. |
