Abstract
A process () for the preparation and conversion of synthesis gas includes reforming a feed gas () comprising methane in a reforming stage () to produce synthesis gas () which includes hydrogen and carbon monoxide. Some of the hydrogen and carbon monoxide is converted to a Fischer-Tropsch product () in a Fischer-Tropsch hydrocarbon synthesis stage (). A tail gas (), including unreacted hydrogen and carbon monoxide, methane and carbon dioxide, is separated from the Fischer-Tropsch product (). In a tail gas treatment stage (), the tail gas () is treated by reforming the methane in the tail gas () with steam () and removing carbon dioxide to produce a hydrogen rich gas (). The tail gas treatment stage () may be either a combined tail gas treatment stage () or a composite tail gas treatment stage. The carbon dioxide from the tail gas treatment stage () is fed to the reforming stage ().
