Enhancement of Fischer-Tropsch process for hydrocarbon fuel formulation

摘要

An enhanced Fischer-Tropsch process for the synthesis of sulfur free, clean burning, green hydrocarbon fuels, examples of which include syndiesel and aviation fuel. Naphtha is destroyed in a hydrogen generator and recycled as feedstock to a syngas (FT) reactor in order to enhance the production of syndiesel from the reactor. A further variation integrates a second hydrogen generator capturing light hydrocarbon gas for conversion to hydrogen and carbon monoxide which supplements the Fischer-Tropsch reactor. The result is a considerable increase in the volume of syndiesel formulated. A system for effecting the process is also characterized in the specification.

主权项

1. A system for synthesizing hydrocarbons, said system comprising:
(a) means for generating syngas lean in hydrogen content; (b) means for catalytically converting said syngas to produce hydrocarbons, containing at least naphtha; (c) a hydrogen generator; (d) circuit means for recycling naphtha to said hydrogen generator to form a hydrogen rich stream; and (e) circuit means for combining said hydrogen rich stream with said hydrogen lean stream to provide a blended and enriched hydrogen content stream for enhancing hydrocarbon production.
