Abstract
A method and apparatus for converting, i.e. hydrogenating, dry particles of coal with hydrogen to give hydrocarbons such as engine or heating fuels. The invention combines together several steps in the hydrogenation process, such as compressing the dry coal, heating, plasticized and hydrogenating, in one apparatus. The apparatus comprises a housing, preferably a cylinder containing a feed and preparation portion of a chamber with a rotatable friction element therein and an immediately adjoining hydrogenation portion of the chamber with a rotating rotor therein and with static mixing nozzles projecting thereinto, through which nozzles heated hydrogen can be injected into the coal which has been brought, by the friction element into a heated, plastic state. The friction element and rotor can be driven by a single drive means, the feed and preparation portion of the chamber can be fed with coal from a hopper through a wheel lock and the hydrocarbon products can be ejected through a valve into a separator.
