Abstract

In a power generation process using a gas turbine for conversion of the energy of gas which is produced by the gasification of a fossil carbon-bearing material such as brown coal, the gas is initially cleaned of dust and optionally desulfurised in the hot condition. The gas is then passed to a combustion chamber in which the temperature of the gas is increased by partial reaction of the gas with air and/or oxygen to a temperature of from 1000.degree. to 1500.degree. before the gas is passed through a catalytic fixed bed reactor arranged upstream of the gas turbine combustion chamber. The combustion chamber in which the gas temperature is increased, the fixed bed reactor and the gas turbine combustion chamber may be combined. The fixed bed reactor contains a nickel-bearing catalyst which, at elevated temperatures, is resistant to ageing and resistant to sulfur and compounds thereof.
