Asymmetric circle running in the cascades gas catalysis

摘要

The invention relates to a method and a device for the production of a product of the synthesis gas, which in addition to the reactants, if appropriate, also the inert components, by means of heterogeneous gas catalysis in the case of incomplete conversion, with the help of a plurality of consecutively connected circulation systems, in which, in each case, the following method steps are performed: (a) synthesis of product, (b) separation of product, (c) division of the residual gas in a discharge part of the current and a feed back part current, (d) wherein the discharge part current is discharged from the circulation system, and (e) of the feedback part current for the synthesis of the same system and / or to a synthesis of an upstream circulation system is returned. The synthesis of the product takes place in all of the circulation systems, with essentially the same pressure. The discharged from the first circulation system, discharge part current is supplied to the succeeding second circulation system, so that at least a part of the gas mixture, which flows through the second circulation system, which has flowed through the first circulation system.
