The first feed stream is introduced into the reactor and reaches a first catalyst bed and is heated by the hydrogenation reaction. Downstream the second feed stream is supplied which will cool down the reaction gas which can then be passed through a second catalyst bed. The content the feed streams can be controlled by adding olefins or dilution gas. The reaction will generate a product gas which will basically contain hydrogen sulphide as a sulphur compound. The temperature of the catalysts and of the gas flow is controlled via the olefin content in the feed streams. The higher the olefin content in the feed stream, the more intense the heating of the gas flow by the hydrogenation heat in the subsequent catalyst bed. | 01-31-2013 |
