    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).

    Abstract: Método para tratar una corriente de gas que comprende hidrógeno y propano, en la que el hidrógeno está presente como componente principal, comprendiendo el método las etapas de: a) proporcionar una membrana que tiene un lado de alimentación y un lado de permeado, siendo la membrana selectiva al hidrógeno con respecto al propano; b) hacer pasar la corriente de gas a través del lado de alimentación de la membrana; e) retirar del lado de alimentación una corriente de retenido empobrecida en hidrógeno y enriquecida en propano en comparación con la corriente de gas; d) retirar del lado de permeado una corriente de permeado enriquecida en hidrógeno y empobrecida en propano en comparación con la corriente de gas; e) someter la corriente de retenido a una destilación a presión elevada por encima de 2 MPa (20 barg) para separar el hidrógeno del propano, y en donde el hidrógeno obtenido en la destilación a presión elevada se combina con la corriente de permeado y se recicla al menos parcialmente.
