A process for producing distillate fuels, such as a diesel fuel, from a syngas feedstream having a relatively low h2/co ratio of greater than 1 and equal to or less than 2.0. The syngas feedstream is preferably passed to a co2 removal zone, then to at least one fischer-tropsch zone, wherein the resulting fischer-tropsch product stream is passed to a separation zone to obtain a hydrocarbon-containing fraction that is hydroconverted to result in a distillate boiling range stream..

Method for revamping a conventional mineral oils refinery to a biorefinery


The invention relates to a method for revamping a conventional refinery of mineral oils into a biorefinery, characterized by a production scheme which allows the treatment of raw materials of a biological origin (vegetable oils, animal fats, exhausted cooking oils) for the production of biofuels, prevalently high-quality biodiesel. This method allows the re-use of existing plants, allowing, in particular, the revamping of a refinery containing a system comprising two hydrodesulfurization units, u1 and u2, into a biorefinery containing a production unit of hydrocarbon fractions from mixtures of a biological origin containing fatty acid esters by means of their hydrodeoxygenation and isomerization, wherein each of the hydrodesulfurization units u1 and u2 comprises: a hydrodesulfurization reactor, (a1) for the unit u1 and (a2) for the unit u2, wherein said reactor contains a hydrodesulfurization catalyst; one or more heat exchangers between the feedstock and effluent of the reactor; a heating system of the feedstock upstream of the reactor; an acid gas treatment unit downstream of the reactor, containing an absorbent (b) for h2s, said unit being called t1 in the unit u1 and t2 in the unit u2, and wherein said method comprises: installing a line l between the units u1 and u2 which connects them in series; installing a recycling line of the product for the unit u1 and possibly for the unit u2, substituting the hydrodesulfurization catalyst in the reactor a1 with a hydrodeoxygenation catalyst; substituting the hydrodesulfurization catalyst in the reactor a2 with an isomerization catalyst; installing a y-pass line x of the acid gas treatment unit t2 of the unit u2; substituting the absorbent (b) in the acid gas treatment unit t1 with a specific absorbent for c02 and h2s.
