Abstract
In a process for producing synthesis gas by catalytic conversion of hydrocarbons contained in a desulfurized feed gas stream with steam, the mixture of feed gas and steam is preheated by heat exchange at a pressure of 10 to 45 bar to a temperature of 300 to 700° C. and is subsequently heated by heat exchange above a catalyst at a pressure of 10 to 45 bar to a temperature of 650 to 950° C. To minimize the apparatus involved, it is provided that the mixture of feed gas and steam traverses a catalyst bed contained in a reaction tank, and the catalyst bed is heated by thermal radiation and convection.
