Coking processes

Patent:

Abstract

A gas suitable for use in containers or motor-vehicles, etc., and consisting mainly of methane, is obtained by distilling at a temperature not exceeding 500/sup 0/C bastard cannel coal, lignite, wood, peat, shale, etc., in an horizontal or vertical retort, through which the material is continuously fed in a thin layer or column by means of a screw conveyor or the like. Cracking or dissociation of the gaseous products is prevented by introducing into the retort part of the gas which is the result of the process and which is compressed to a pressure of at least 15 atmospheres and allowed to expand into the retort to cool and carry away the gaseous products produced. These are then passed through condensers for extracting liquid hydrocarbons, and other hydrocarbons are extracted by passage through washing-oils. The gas is then compressed by a water-cooled pump to a pressure of 15 atmospheres, whereby a spirit similar to petrol is formed, and a stable gas left which is mainly methane, part of the gas being used to carry out the process described above.
