    Abstract: In a process for the catalytic pressure refining of light oils obtained by gasification, coking, low-temperature carbonization or cracking of liquid or solid fuels with hydrogen or hydrogen-containing gases, the raw materials which contain compounds capable of polymerization and/or condensation are heated up and introduced into a hot stream of hydrogen or hydrogen-containing gases in the form of such a fine mist that an immediate vaporization of the raw materials occurs, the heating-up and vaporization being carried out so rapidly that the speed of the heating-up and vaporization process exceeds the polymerization and/or condensation speed in the liquid phase, and the resultant mixture is heated up to reaction temperature and subjected to catalytic hydrogenative refining, for example over a cobalt-molybdenum-alumina catalyst. The raw material may be sprayed into a preheated gas stream by means of an injection nozzle or atomizer, which is desirably cooled, and may be provided with a filter. A prerefining catalyst may be interposed before or in the heating-up zone.

    Abstract: A process for the manufacture of a bifunctional catalyst for the conversion of hydrocarbons, which contains a crystalline aluminosilicate of the type of the Y-zeolites as the acidic component and a noble metal as the hydrogenation component. The process constitutes a technologically simple way of manufacturing bifunctional zeolite catalysts which have at least the same activity and the same life as the catalysts manufactured by conventional methods, coupled with great heat stability and exhibit activity in the presence of H2O, H2S and NH3 at relatively high temperatures.

    Abstract: 1,165,064. Refining catalysts. BADISCHE ANILIN-& SODA-FABRIK A.G. 6 Jean., 1967 [8 Jan., 1966], No. 926/67. Heading B1E. [Also in Division C5] A catalyst for the selective hydrofining of pyrolysis gasolines comprises metallic Co and/ or Ni with a small amount of Pd on a carrier having an internal surface area of more than 100 sq. m/g. The carrier may be an active Al 2 O 3 , e.g. boehmite, or a silicate of Mg, Zn, or Al. The content of Co and/or Ni may be from 5-35% and the content of Pd may be 0.01-0.1% by weight.

    Abstract: A process for the continuous selective refining of gasolines which have been obtained by pyrolytic cracking of mineral oils or fractions thereof in the presence of hydrogen at elevated temperature and superatmospheric pressure wherein a catalyst is used which contains metallic cobalt with an addition of copper and/or molybdenum oxide supported on a carrier having a specific surface of 100 m.2/gm. or more. The carrier may be a silicate of zirconium, titanium, magnesium or zinc or mixtures thereof, and/or aluminium oxide. A silicate of cobalt may be used, the silicic acid formed by reduction acting as a carrier. The reaction temperature may be 50-250 DEG C., the catalyst loading 0.5 to 5 kg. of gasoline per litre of catalyst per hour, and the ratio of hydrogen to gasoline should be low but not less than 100 litres/kg.; the pressure is such that most of the gasoline is in the liquid phase.

    Abstract: The hydrofining of hydrocarbons, such as crude benzene or sulphur-containing unsaturated gasolines, obtained from the coking, low temperature carbonization or gasification of solid or liquid fuels is effected in the presence of two or more catalysts having different selective activities of which one comprises at least on compound of a Group V or VI metal together with a compound of nickel and/or cobalt and another comprises at least one compound of a Group V or VI metal alone or with a compound of iron. The two catalysts may be mixed or used in series. The former catalysts may comprise the oxides and/or sulphides of vanadiu, molybdenum, tungsten and chromium with an oxide and/or sulphide of nickel or cobalt, the relative proportions being about equal; the catalyst may form 1-20% by weight of a composition, the remainder being a carrier, e.g. alumina magnesia, zinc oxide, titania, silicic acid, a silicate, zirconia or cerium oxide, any of which may be pretreated with hydrogen, hydrogen fluoride, chloride or iodide, a mineral acid or a low molecular weight organic acid. The other catalyst may comprise an oxide and/or sulphide and/or halide of molybdenum, vanadium, chromium or tungsten together with a minor proportion of an oxide, sulphide, halide, formate, acetate or oxalate of iron, if desired. This catalyst may also be carried on a support. Suitable conditions are 300 DEG -450 DEG C., 5-200 atmospheres and 0,3-6 Kg. of hydrocarbon per litre of catalyst per hour, the hydrogenating gas being hydrogen, cokeoven gas, water gas or town gas. The process removes sulphur compounds and reduces the olefin content.ALSO:The hydrofining of hydrocarbons, such as crude benzene or sulphur-containing unsaturated gasolines, obtained from the coking, low temperature carbonisation or gasification of solid or liquid fuels is effected in the presence of two or more catalysts having different selective activities of which one comprises at least one compound of a Group 5 or 6 metal together with acompound of nickel and/or cobalt and another comprises at least one compound of a Group 5 or 6 metal alone or with a compound of iron.
