Abstract
The invention relates to a method and a system for operating a Fischer-Tropsch synthesis, wherein a feed gas comprising CO and Hfrom coal gasification () is desulfurized and subsequently fed into a Fischer-Tropsch synthesis as an input gas, wherein hydrocarbons are formed from carbonic oxides and hydrogen by catalytic reactions. The hydrocarbons are separated as liquid products (), and a gas flow comprising CO and CO2 exiting the Fischer-Tropsch synthesis unit () is compressed and fed into a conversion stage, wherein CO and steam are transformed into Hand CO. In the method according to the invention, the gas exiting the conversion stage is fed back into the Fischer-Tropsch synthesis unit as a gas rich in H, together with the desulfurized input gas, after the gas is prepared in that COand/or further components other than Hare removed.
