Abstract

A method for the production of high-caloric content gases is disclosed wherein feed gases containing CO and H.sub.2 are passed through at least two consecutive catalytic fluidized bed stages having cooling elements wherein, the feed gases being introduced to the first stage under pressure and to the subsequent stages under a pressure which is less than the pressure of the next preceding stage, and the gas produced from each preceding stage is fed to the next stage as a diluting gas. As a result of using the method of the present invention, one can avoid the necessity of compression of the feed gases in the subsequent reaction stages, thereby decreasing the cost as well as the technical difficulties encountered in the process.
