| 摘要 |
A gas-to-liquids plant (10) for treating natural gas (5) includes a synthesis-gas-producing catalytic reactor (30) to produce a synthesis gas containing hydrogen and carbon monoxide, and a Fischer-Tropsch synthesis reactor (55) for generating hydrocarbons, and producing a tail gas, and also means (52) to generate a hydrogen-rich gas stream (34) from the synthesis gas or from the tail gas. The plant (10) also incorporates a hydrogen- desulphurisation reactor (87, 90) and means (86) to supply both the natural gas and the hydrogen-rich gas stream to the hydrogen-desulphurisation reactor during normal operation. The plant (10) also may comprise a hydrogen production module (92, 95) for use at start-up of the plant. The reactor (30) may comprise a partly-sacrificial catalyst bed.
