Abstract

A method of catalytic conversion of feed gases, particularly of a low-sulphur gas mixture rich in carbon monoxide and hydrogen, into a product gas mixture containing methane and/or higher hydrocarbons under high pressure includes the step of removing heat of reaction from the catalytic conversion from a reaction zone by feeding both water and steam to form a cooling medium through a pipe coil in the reaction zone. This forms superheated steam in the pipe coil and the superheated steam is then converted into another form of energy, for example in a turbo-generator. Preferably the reaction zone is a fluidized bed. The apparatus for carrying out this method comprises a reactor, which is preferably a fluidized bed reactor and in this reactor the piping system forming the superheater is disposed in the lower part of the reaction zone. The superheater is connected to a feedwater line and to a steam inlet line and a steam turbine is connected to a steam output line leading from the superheater.
