Abstract
A process of converting a feed of hydrocarbon-containing gases into liquid hydrocarbon products including a first reaction of converting the feed into one to 2.5 parts of hydrogen to one part carbon monoxide in the presence of carbon dioxide and then secondly reacting the hydrogen and carbon monoxide in a Fischer-Tropsch synthesis reactor using a promoted iron oxide catalyst slurry to form liquid hydrocarbon products, wherein the carbon dioxide from the first and second reactions is separated from the product streams and at least a portion of the separated carbon dioxide is recycled into the first reaction feed and the hydrocarbon products are separated by distillation and a normally gaseous portion of the separated products are further reacted in another Fischer-Tropsch synthesis reactor to produce additional liquid hydrocarbon product.
