Title: Process for the destructive hydrogenation of distillable carbonaceous materials
IPC: C10G1/06
Filed: 1932-07-07
Abstract: The production of hydrocarbons by the heat treatment of distillable carbonaceous materials in presence of hydrogenating gases is carried out in the presence of catalysts comprising one or more of the halogens chlorine, bromine and fluorine, in conjunction with at least one of the metalloids carbon, silicon, phosphorus, sulphur, selenium, tellurium, arsenic, antimony, and boron, and in addition a metal oxide, hydroxide, sulphide, or phosphate, or a metal or its compounds of groups 5 and 6 of the periodic system.  If the metalloids phosphorus, sulphur, selenium, tellurium, silicon, or boron are used iodine may be employed instead of or with the other halides.  The halogen and the metalloid may be used in combination, e.g. chloroform, halides of benzene, naphthalene, toluene, xylene, phenol, cresol, anthraquinone or nitrobenzene, or methyl chloride, ethyl chloride, methylene bromide, ethylene chloride or the corresponding bromides or iodides, or bromoform, fluoroform, fluorobenzene or fluoronaphthalene or the tetrahalides of carbon.  Phosphorus pentaand trihalides, phosphorus sulpho-chloride and similar compounds of the other metalloids and complex compounds of metal halides with the metalloid halides may also be used.  Carriers and dispersion agents may be added.  Examples are given of the treatment of (1) an oil in presence of ethylene bromide with tungsten disulphide and molybdenum, zinc, and magnesium oxides. (2) coal paste impregnated with ammonium molybdate in presence of chlorobenzene (3) phenol in the presence of carbon tetrachoride and rhenium sulphide (4) cracked benzine in presence of benzyl chloride and cobalt and tungsten suphides.  A small amount of a hydrogen halide may be added to the hydrogenating gases. Specifications 335,522, [Class 32, Distilling &c.], and 364,785 are referred to.ALSO:The production of hydrocarbons by the heat treatment of distillable carbonaceous materials in presence of hydrogenating gases which includes the conversion of oxygen and sulphur containing organic compounds into aromatic hydrocarbons is carried out in the presence of catalysts comprising one or more of the halogens chlorine, bromine and fluorine, in conjunction with at least one of the metalloids carbon, silicon, phosphorus, sulphur, selenium, tellurium, arsenic, antimony, and boron, and in addition a metal oxide, hydroxide, sulphide, or phosphate, or a metal or its compounds of groups 5 and 6 of the periodic system.
