Abstract
PURPOSE: To effect efficient gasification by reacting a metal oxide having little endothermic reaction heat when reduced with carbon as a gasification agent, with a carbonaceous material in a fluidized layer and oxidizing the reduced gasification agent for reuse, in the gasification of a carbonaceous material.
CONSTITUTION: Carbonaceous material 27 such as coarse coal is supplied together with a gasification agent consisting of a coarese metal oxide 25 (e.g., copper oxide or manganese oxide) having little endothermic reaction heat when reduced with carbon to multi-stage fluidized layer 1, where it is fluidized by the introduction of oxygen 2, steam 3, etc. and gasifed by a reaction as shown by the formula, to obtain gas 18 rich in CO, H2, etc. Metal 6 reduced in the gasification step is sent together with ask contained in the carbonaceous material 27 to separator 12, in which it is separated from the ask, and converted into the metal oxide 25 by oxidation with air 13. The metal oxide 25 is reused by being recycled to the fluidized layer 1.
