    Abstract: Gasification of carbon-containing raw material into gasified gas and recovery of CO 2 are enabled at the same pressure throughout a system. Provided are a hydration tower 1 for performing hydration reaction by contact of CaO with water vapor while keeping at a predetermined pressure and a temperature at or below an upper limit for production of Ca(OH) 2 ; a gasification reactor 2 with a water removal section 2a for dehydration of Ca(OH) 2 introduced through heating to obtain highly active CaO and with a gasification section 2b for production of char through reaction of a raw material with water vapor and production of gasified gas through gasification of the char, CO 2 being absorbed by CaO from the section 2a to produce CaCO 3 , heat of reaction at that time being used for the gasification of the raw material, the gasified gas being used as a heat source for the dehydration in the section 2a; and an absorbent regeneration tower 3 in which, in the presence of the char-containing CaCO 3 from the section 2b, CO 2 , water vapor and oxygen, CaCO 3 is calcined with heat of combustion of the char to separate it into CO 2 and CaO, the resultant CaO being supplied to the hydration tower 1. The pressure in the reactor 2 and in the tower 3 connected to the tower 1 is the same as pressure in the tower 1.
