Abstract: The present invention relates to a method for processing a low-temperature Fischer-Tropsch process effluent (1) into a fuel product, the method comprising fractionating the Fischer-Tropsch effluent in a first fractionation (2), separating water and oxygenates (4); and processing a fraction consisting mainly of C17 and higher hydrocarbons by a catalytic hydrocracking (21) to produce a hydrocracked liquid product (22) and a further fraction consisting mainly of C17 and higher hydrocarbons (23). Thereafter the liquid products are processed by catalytic hydroisomerisation (7) to produce a product mixture (8), which is fractionated in a second fractionation (9) and a third fractionation (14). The method further comprises directing at least some of the gases to a reverse water gas shift reaction (18); and recycling a heavy fraction consisting mainly of C17 and higher hydrocarbons (23) to the first fractionation (2).
