Abstract
Increased hydrocarbon yields from natural gas and reduced oxygen consumption improvements are obtained by recycling hydrogen to a Fischer-Tropsch reactor, which can have a catalyst exhibiting either a low water gas shift activity such as cobalt, or a high water gas shift activity such as iron. At least a portion of the remaining tail gas, either before or after the hydrogen has been removed, is recycled to the inlet of the synthesis gas production reactor.
