    Abstract: Vaporizable hydrocarbons boiling in the range 30 DEG to 200 DEG C are catalytically cracked with steam at 600 DEG to 950 DEG C. in the presence of a calcined catalyst comprising nickel, magnesium oxide and aluminium oxide. Gasoline fractions may thus be cracked at pressures up to 40 atmospheres, without catalyst decomposition or carbon deposition. Excess steam may be used, e.g. 4 to 5 moles steam per gram atom of carbon at pressures above 5 atmospheres. The catalyst may comprise, percentages by weight, 10 to 30% Ni, 10 to 70% MgO, and 10 to 65% Al2O3, and calcining is at over 1050 DEG C., e.g. 1100 DEG to 1250 DEG C. Two specific examples are described, including the compositions of the methane-containing gases produced.

    Abstract: 1,156,156. Making combustible gas. BADISCHE ANILIN- & SODA-FABRIK A.G. 10 Nov., 1966 [11 Nov., 1965], No. 50418/66. Heading C5E. In a process for continuously cracking gaseous and/or vaporizable hydro-carbons, e.g. methane, natural gas, and liquefied low boiling hydrocarbons, with steam and optionally with oxygen, to produce H 2 - and CO-containing gases, the feed is passed through a bed of catalyst located in the annular space between inner and outer concentric tubes, the bed being heated by direct firing of the walls of both the tubes. The source of heat for the inert tube is one or more burners, preferably a single longitudinal burner, at one end of the tube, and several burners normal to the external wall of the outer tube. The tubes may be cylindrical or conical, and may be corrugated on the faces contacting the catalyst, which is preferably nickel and may contain alkali metal oxides. Preferred temperatures are 700‹ to 900‹ C., and pressures up to 50 atmos are mentioned. The object of the invention is to prevent a temperature gradient across the catalyst.

    Abstract: 1,129,114. Making combustible gas. BADISCHE ANILIN- & SODA-FABRIK A.G. 16 Nov., 1965 [17 Nov:, 1964], No. 48541/65. Heading C5E. 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.

    Abstract: The production of olefins or producer gas is effected by vaporizing a vaporizable liquid hydrocarbon mixing it with oxygen or air and steam or carbon dioxide, and introducing it at atmospheric or increased pressure through a burner into a reaction chamber and simultaneously introducing a non-vaporizable liquid hydrocarbon through an atomizing jet in the same burner into the mixture of vaporized hydrocarbon and gases. Vaporizable hydrocarbons are hydrocarbons which can be vaporized without leaving a residue, e.g. light gasoline, liquefied gases and petroleum distillates; non-vaporizable hydrocarbons are those which cannot be vaporized without leaving a residue, e.g. crude oils, residue oils and oils containing compounds forming non-volatile resins. The vaporizable and non-vaporizable liquids may be obtained from a single feed by passing into a vaporizer, the nonvaporizable portion being recovered from the sump. Suitable conditions are 600 DEG -2,000 DEG C. and up to 30 atmospheres. In the drawing, vaporizable hydrocarbon enters through vaporizer 1, and gases by line 3 and after mixing flow through the annular space 4 of the burner 2. Liquid hydrocarbon is preheated before spraying through jet 7 which is drawn back to prevent wetting of the reaction chamber walls. The whole mixture is ignited. The reaction chamber may be empty or filled with coke or other inert solid or catalyst.
