ABSTRACT:
An apparatus for the production of heavier hydrocarbons from one or more gaseous light hydrocarbons is provided. The process of using the apparatus comprises reacting the gaseous light hydrocarbons by autothermal reforming with air in the presence of recycled carbon dioxide and steam to produce a synthesis gas stream containing hydrogen and carbon monoxide. The synthesis gas stream is reacted in the presence of a hydrocarbon synthesis catalyst containing cobalt to form heavier hydrocarbons and water from the hydrogen and carbon monoxide. The heavier hydrocarbons and water are separated, and the resulting residue gas stream is subjected to catalytic combustion with additional air to form a product stream comprising carbon dioxide and nitrogen. The carbon dioxide is separated from the nitrogen to produce a nitrogen product stream, and at least a portion of the separated carbon dioxide is recycled to the autothermal reforming step.
