INSTALLATION FOR HYDROGENOPYROLYSIS OF COAL AND LIGNITE

摘要

The apparatus is intended to carry out the operation of hydrogenopyrolysis in a moving fluidized bed reactor operating under high pressure and in which the fluidization is provided by a gas rich in hydrogen, at high temperature, used both as an agent of fluidization, as a chemical reagent and as a carrier of the heat necessary for heating the solid fuel The apparatus comprises a device for heating the gas by electric arc (14) (of the order of 2,000 C) and a fluidization reactor ( 4), at the base of which the coal is introduced under pressure by a lateral feeder (3) of conventional type, heating device and reactor being arranged from bottom to top inside a cylindrical metal casing (18) of large height and relatively small diameter, and a heat exchanger (5) consists of metal surfaces, one side of which is in direct contact with the bed of solid fuel and the other side of which is cooled by the circulation. ation of a gas or a liquid.
