ABSTRACT:
A process for the production of normally gaseous, normally liquid and optionally normally solid hydrocarbons from a light hydrocarbonaceous feed gas stream, which feed gas stream includes sulphur compounds and carbon dioxide, the process comprising the steps of: (i) removing at least most of the sulphur compounds from the feed gas stream by an aqueous amine process in one or more reactors, optionally followed by on or more further treatment processes; (ii) controlling where necessary the amount of carbon dioxide in the feed gas stream in step (i) so as to be in the range 0.25-2.0 v/v&, preferably 0.5-1.5 v/v %, of the processed feed stream; (iii) using the feed gas stream of step (ii) to provide synthesis gas; and (iv) catalytic converting the synthesis gas of step (iii) at an elevated temperature and pressure to obtain the normally gaseous, normally liquid and optionally normally solid hydrocarbons.
