Abstract
A process () to produce Fischer-Tropsch products includes feeding feed synthesis gas () with a substantially constant target feed synthesis gas H/CO ratio to a Fischer-Tropsch synthesis stage (). A portion of the feed synthesis gas () is converted to Fischer-Tropsch products in the Fischer-Tropsch synthesis stage (). The Fischer-Tropsch products () from the Fischer-Tropsch synthesis stage () are withdrawn. A Fischer-Tropsch synthesis stage tail gas () which includes unconverted Hand CO is obtained. The operating conditions of the Fischer-Tropsch synthesis stage () are manipulated to achieve a substantially constant target tail gas H/CO ratio, with the target tail gas H/CO ratio being substantially different from the target feed synthesis gas H/CO ratio.
