Title: Improvements in the production of valuable organic compounds from carbonaceous materials by hydrogenation or reduction
IPC: C10G1/00
Filed: 1932-08-26
Abstract: Oils are obtained from solid carbonaceous materials by depositing thereon from solution or suspension oxides or hydroxides or compounds giving rise thereto and subjecting the impregnated materials to treatment with hydrogenating gases at elevated temperature and under atmospheric pressure.  Oxides or hydroxides of molybdenum, tungsten, tin, chromium and cobalt may be used and may be applied as solutions of ammonium salts, e.g. ammonium molybdate or of nitrates, i.e. nickel nitrate and subsequently converted by reduction or other treatment to the respective oxides.  The impregnated material after dehydration is passed with the hydrogenating gases by means of conveyers through tubes &c. heated to 300-500 DEG  C.  The gas may be preheated and introduced at intervals along the tubes.  The residual ash is treated for recovery of catalyst, e.g. by washing with ammonia solutions, when the vapours produced are separated from the gases which may be treated for recovery of ammonia.  The vapours may be subjected to cracking in the vapour phase to produce olefines. Hydrocarbon vapours, carbon monoxide, water gas, town gas, Mond gas, producer gas &c. may be used as the hydrogenating gases. Phenols may be removed from the reaction products by washing with alkali and reduced by further hydrogenation in presence of catalysts. Pulverised bituminous coal is mixed with its own weight of a 15 per cent solution of ammonium molybdate and after passage through a dryer to remove part of the water, is led through an inclined rotary connector heated to 470 DEG  through which hydrogen is passed from the discharge end.  The vapours produced after washing to remove ammonia are heated to 650 DEG  C. in narrow pipes and the products treated to recover olefines.ALSO:Oils are obtained from solid carbonaceous materials by depositing thereon from solution or suspension oxides or hydroxides or compounds giving rise thereto and subjecting the impregnated materials to treatment with hydrogenating gases at elevated temperature and under atmospheric pressure.
