PROCESS AND APPARATUS FOR THE PARALLEL PRODUCTION OF DIFFERENT SYNTHESIS GASES

摘要

The invention relates to a process and an apparatus for the parallel production of at least two synthesis gases (10, 11) having different compositions from a hydrocarbon-containing starting material (1) which is, after mixing with steam (2) and/or carbon dioxide (3), fed to a steam reformer (R) and there converted into synthesis gas by steam reforming in at least two catalyst tubes (K1, K2, K3) operated in parallel. It is characteristic of the invention that at least two mixtures (6, 9) having different compositions are formed from the hydrocarbon-containing starting material (1) by division and addition of steam (2) and/or carbon dioxide (3), where each of the different mixtures (6, 9) is fed as exclusive feed to a catalyst tube or a group of catalyst tubes (K1, K2, K3) of the steam reformer (R) and converted into synthesis gas (10, 11).

主权项

1. A process for the parallel production of at least two synthesis gases (10, 11) having different compositions from a hydrocarbon-containing starting material (1), comprising:
dividing a stream of hydrocarbon-containing starting material (1) into at least two feed substreams and then forming, by addition of steam (2) and/or carbon dioxide (3), at least two feed mixtures (6, 9) having different compositions, and
feeding each of said at least two feed mixtures (6, 9) as exclusive feed to a catalyst tube or a group of catalyst tubes (K1, K2, K3) of a steam reformer (R), wherein each of said at least two feed mixtures (6, 9) is converted into a synthesis gas (10, 11), whereby at least two synthesis gases (10, 11) having different compositions are formed.
