Abstract

See full text

The present disclosure provides a Fischer-Tropsch tail gas recycling system, including: a Fischer-Tropsch reactor providing a source of tail gas; a first preheater for preheating the tail gas to between about 200 and 300 degrees C.; a hydrogenator for hydrogenating the tail gas; an expansion device for reducing the pressure of the tail gas to between about 2.5 and 5 bar; a second preheater for preheating a feed gas comprising the tail gas and steam to between about 500 and 600 degrees C.; and a catalytic reformer for reforming the feed gas in the presence of a catalyst, wherein the catalytic reformer operates at about 2 bar and about 1000 degrees C., for example. Optionally, CO2 and/or natural gas are also added to the tail gas and/or steam to form the feed gas.
