Patent GB-432638-A (GB)
Title: Improvements in the manufacture and production of valuable hydrocarbon oils by treatment of distillable carbonaceous materials at elevated temperatures and in the presence of catalysts and/or surface-active materials
IPC: C10G1/08
Filed: 1934-01-25
Abstract: <PICT:0432638/IV/1> In the production of valuable hydrocarbons by the heat treatment of carbonaceous materials, particularly in presence of hydrogenating gases, and of finely divided catalysts or surface active materials suspended in the reaction materials, a part of the materials containing catalyst is returned to the preheater from a settling vessel which is arranged behind the preheater and before a reaction chamber or is connected with any place in the preheater behind the point of return.  The catalyst can be added in one or more stages during or after the preheating. Carbonaceous materials are mixed with catalyst in a vessel and pumped with hydrogen from an inlet 6 through a preheater 3 in which the materials are heated by heat exchange with hot reaction products.  The materials then pass to a settling vessel 4 from which a part is returned by a pump 5 to the preheater 3 while the remainder is passed through a second preheater 8 into the reaction vessel 9.  The vaporous products are separated from the liquid products in a separator 10 and pass through the preheater 3 and a condenser to a separator 12 from which gases are recycled through a washer 13 to the hydrogen pump 7.  The treatment may comprise cracking, destructive hydrogenation, refining oils, conversion of oxygen or sulphur containing organic compounds into the corresponding hydrocarbons, aromatization, and the conversion of unsaturated hydrocarbons into hydroaromatic hydrocarbons. Examples are given of the treatment with hydrogen of brown coal neutralized with hydrochloric acid in the presence of ammonium molybdate and carbon tetrachloride.ALSO:<PICT:0432638/III/1> In the production of valuable hydrocarbons by the heat-treatment of carbonaceous materials, particularly in presence of hydrogenating gases, and of finely divided catalysts or surface-active materials suspended in the reaction materials, a part of the materials containing catalyst is returned to the preheater from a settling vessel which is arranged behind the preheater and before a reaction chamber or is connected with any place in the preheater behind the point of return.
