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 the wash fluid is recycled in a closed loop with a dedicated scrubber, stripper and splitter. The wash fluid preferably is kerosene or LDF. The C3+ hydrocarbons that are recovered from the off-gas are, together with other Fischer-Tropsch product, subjected to hydrocracking or hydrocracking/hydroisomerization. Additionally, hydrogen is recovered from the off-gas.
