Hydrocarbon recovery from Fischer-Tropsch off-gas

摘要

The invention pertains to a method for processing a Fischer-Tropsch off-gas wherein Fischer-Tropsch off-gas is contacted with a wash fluid in a scrubber, and wherein wash fluid with C 3 + hydrocarbons is subjected to hydrocracking and/or hydrocracking/hydroisomerisation in a cracking unit. The wash fluid preferably is kerosene which is recycled from the scrubber via a separation unit, a cracking unit and a separation unit, back to the scrubber.
