摘要： The present invention relates to a hydroconversion process of a heavy oil feedstock comprising: (a) preparing a conditioned feedstock (103) by mixing said heavy oil feedstock (101) with a catalyst precursor formulation (104) so that a colloidal or molecular catalyst is formed when it reacts with sulfur, said catalyst precursor formulation (104) comprising a catalyst precursor composition (105) comprising Mo, an organic additive (102) comprising a carboxylic acid function and/or an ester function and/or an acid anhydride function, and a molar ratio organic additive (102)/Mo from formulation (104) ranging between 0.1:1 and 20:1; (b) heating said conditioned feedstock; (c) introducing the heated conditioned feedstock (106) into at least one hybrid ebullated-entrained bed reactor comprising a hydroconversion porous supported catalyst and operating said reactor in the presence of hydrogen and at hydroconversion conditions to produce an upgraded material (107), the colloidal or molecular catalyst being formed during step (b) and/or (c).

摘要： The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300° C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250° C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h−1. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300° C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.

摘要： The present invention relates to a slurry hydroconversion process of a heavy oil feedstock comprising: (a) preparing a first conditioned feedstock (103) by blending said heavy oil feedstock (101) with an organic chemical compound (102) comprising at least one carboxylic acid function and/or at least one ester function and/or an acid anhydride function; (b) preparing a second conditioned feedstock (105) by mixing a catalyst precursor composition (104) with said first conditioned feedstock so that a colloidal or molecular catalyst is formed when it reacts with sulfur; (c) heating the second conditioned feedstock in at least one preheating device; (d) introducing the heated second conditioned feedstock (106) into at least one slurry bed reactor and operating said slurry bed reactor in the presence of hydrogen and at hydroconversion conditions to produce an upgraded material (107), the colloidal or molecular catalyst being formed during step (c) and/or (d).

摘要： The invention relates to a process for converting a heavy hydrocarbon feedstock containing a fraction of at least 50% with a boiling point of at least 300° C., and containing sulfur, Conradson carbon, metals, and nitrogen, comprising at least two successive hydroconversion steps, which may be separated by an intermediate separation step, and at least one step of deasphalting a heavy fraction of the effluent resulting from the hydroconversion, with recycling at least one portion of the deasphalted oil (DAO) during the hydroconversion, downstream of the first hydroconversion step. The DAO is either recycled at the outlet thereof from the deasphalter, or after having undergone a fractionation step that produces a heavy fraction of the DAO that then constitutes the portion of the DAO that is recycled. This process makes it possible to simultaneously improve the degree of conversion and the stability of the liquid effluents.
