Abstract
A gasification process is divided into three processes: a gasification furnace for carrying out gasification process by pyrolysis and gasification (pyrolysis gasification phase, first process), a combustion furnace for burning char to obtain calcined active chemical (char combustion phase, second process) and a gas purification furnace for purifying gasified gas (gasified gas purification phase, third process). Through heat transmission by the fluid heat medium and chemical reactions in respective phases by the chemical, the gasification furnace is independently controlled to a low or medium temperature (773-1073 K) which is required for gasification and which enables absorption of CO; and the gas purification furnace is controlled to a high temperature (1073 K or more) required for gas purification.
