This invention relates to a gasification power generation process wherein a product gas A1 obtained by the gasification of coal or petroleum is used as the fuel of a gas turbine 4 for electric power generation, the process comprising the steps of dedusting product gas A1, introducing product gas A1 directly into gas turbine 4 as the fuel thereof to effect electric power generation, and subjecting the exhaust gas A2 discharged from gas turbine 4 to a gas purification treatment including at least desulfurization. This invention can provide a gasification power generation process which is more suitable for practical use from an economic point of view in that a high degree of exhaust gas purification and a marked improvement in thermal efficiency can be achieved and, moreover, the construction of the equipment for carrying out a gas purification treatment including desulfurization can be highly simplified.
