Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/28
Filed: 1950-01-17
Abstract: <PICT:0697727/III/1> Petroleum hydrocarbons are desulphurized by passing the hydrocarbons in vapour form in admixture with hydrogen and a granular dehydrogenation-hydrogenation catalyst to a reaction zone wherein the catalyst forms a solid moving bed, contacting the hydrocarbons with the catalyst at a temperature and pressure such that the dehydrogenation of naphthenes contained in the hydrocarbons is effected to an extent not substantially in excess of that required to provide sufficient hydrogen to convert organically combined sulphur into hydrogen sulphide and to maintain the necessary pressure in the reaction zone, continuously removing treated hydrocarbons from the reaction zone.  Hydrogen sulphide and a hydrogen-rich gas are separated from the treated hydrocarbons and the latter is recycled to the reaction zone as the sole hydrogen supplied thereto.  Spent catalyst is continuously removed from the reaction zone, regenerated, and returned to the reaction zone.  The process may be carried out at a pressure of 50-200 lb./sq. in. and at a temperature of 750-800 DEG F.  The preferred catalyst is cobalt molybdate supported on alumina. In the Figure, catalyst is fed from a hopper 13 via line 14 and petroleum hydrocarbons and recycle gas via line 17, into the reactor 10.  The treated hydrocarbons and recycle gas pass out of the zone via line 19 to a cooler and separator.  Spent catalyst passes through a purging section 20, where residual hydrocarbons are steam stripped, and the catalyst is fed through line 22 into regenerator 11, into which air and nitrogen or superheated steam are injected by line 24. The temperature of the regenerator is controlled by cooling coils 25. Regenerated catalyst flows through a seal leg 28 to a hopper 29, where it is picked up by a stream of flue gas introduced by line 30, and lifted to the upper hopper 13, from which the flue gas is vented by line 32.  Part of the flue gas leaving the regenerator 11 via line 34 is passed by line 30 to the lower catalyst hopper 29. Examples are given of the treatment of a wax distillate and a gas oil.  Aromatic extracts and other feedstocks boiling up to 350 DEG C may also be treated similarly to the gas oil.  Specifications 654,152, 663,038, 669,536, 669,551, 669,552, 669,553, 697,083, 697,222, 697,226 and 697,724 are referred to.

Title: Controlled oxidation of branched chain hydrocarbons and halo-substituted branched chain hydrocarbons
IPC: F02B47/00
Filed: 1944-01-25
Abstract: Tertiary alkyl hydro-peroxides and di-(tertiary alkyl) peroxides are produced by reaction of a hydrocarbon containing at least one tertiary carbon atom of aliphatic character or a halo-substituted derivative thereof with oxygen or oxygen-containing gas in the presence of a hydrogen halide at an elevated temperature below that producing spontaneous combustion. The initial hydrocarbons have the formula <FORM:0577841/IV/1> , where each R is a like or different alkyl, aryl, aralkyl or alicyclic radical, two of which together may form an alicyclic ring.  Mixtures of such hydrocarbons may be used to produce asymmetrical peroxides.  Hydrocarbons specified are isobutane, 2-methyl and 2-ethyl butane, 2-methyl and 3-methyl pentane, 2,3- and 2,4-dimethyl butane, and their homologues, isopropyl benzene, and 1-phenyl-1- or 2-methyl propane.  Temperatures are generally about 150-200, but may range from 100-250 DEG  C. or more, especially when inert diluents are present, e.g. steam, nitrogen, carbon monoxide and methane.  Hydrogen bromide is the preferred catalyst, but other hydrogen halides, for example the chloride, may be used.  Proportions of reactants and conditions are generally the same as described in Specification 574,958.  The products, besides alcohols, are hydro-peroxides, and peroxides of the formula <FORM:0577841/IV/2> , where each R in particular represents a saturated alkyl radical, e.g. tertiary butyl.  Such peroxides are used to catalyse formation of plastics such as diallyl phthalate and/or acrylate resins, and to improve the octane value of diesel fuels.  In an example, isobutane, oxygen and hydrogen bromide in a ratio of 2 : 2 : 1 is passed through a coil of glass tubing at 158 DEG  C. for a time of about 3 mins. and di-(tertiary butyl) peroxide isolated from the products which also include tert.-butyl alcohol.
