PRODUCTION OF A SYNTHESIS GAS BLEND AND USE IN A FISCHER-TROPSCH PROCESS

摘要

The invention is directed to a process for the production of hydrocarbon products from a methane comprising feed-stock comprising of the steps of: preparing a feed syngas comprising hydrogen and carbon monoxide having a hydrogen/carbon monoxide molar feed ratio in a syngas manufacturing process and using the feed syngas in a Fischer-Tropsch process using one or more fixed bed catalyst beds as present in one or more syngas conversion reactors thereby obtaining the hydrocarbon product and an residual tail gas. The manufacturing process comprises of two parallel operated syngas manufacturing processes starting from the same gaseous methane comprising feedstock. One syngas manufacturing process is a partial oxidation (POX) process which prepares a syngas having a hydrogen/carbon monoxide [H2/CO] molar ratio below the molar feed ratio and The second syngas manufacturing process is a heat exchange reforming (HER) process, which prepares a syngas having a hydrogen/carbon monoxide [H2/CO] molar ratio above the molar feed ratio.
