Abstract

The invention relates to a reforming module for converting hydrocarbon-containing fuel gases to hydrogen-containing process gases, wherein the catalytic reaction occurs on the surface of a plate catalyst, said module constructed such that the hydrocarbon-containing fuel gas before entering the catalyst chamber flows through a tubular heat exchanger by means of which the hydrocarbon-containing fuel gas is preheated through utilization of the heat content of the reformed process gas and that the catalyst-bearing plates are designed in the form of heat exchangers, through which flow the cathode waste gas and the waste gases from a catalytic combustion chamber, in which the residual amounts of hydrogen, carbon dioxide, and carbon monoxide, present in the process gas, are combusted catalytically after the electrochemical process. In particular, the reforming module of the invention is distinguished in that it has a bypass inlet to an upstream tubular heat exchanger, through which cold hydrocarbon-containing fuel gas can be passed into the catalyst chamber. This offers the advantage of optimal process control of the catalytic reforming process without affecting the total volumetric flow.
