    摘要： A catalytic system characterized in that it comprises: a first catalyst, having a hydrogenating function, consisting of solid particles of which at least 95% by volume having an equivalent diameter smaller than 20 μm, containing one or more sulfides of metals of group VI and/or VIII B, possibly prepared starting from an oil-soluble precursor of the same; and a second catalyst, having a cracking function, consisting of solid particles of which at least 90% by volume having an equivalent diameter larger than 5 μm and smaller than 5 mm, containing an amorphous silico-aluminate and/or a crystalline silico-aluminate and/or an alumina, the equivalent average diameter of the solid particles of the second catalyst being greater than the equivalent average diameter of the solid particles of the first catalyst. Said catalytic system can be used in a process for the hydroconversion of heavy oils which comprises sending the heavy oil to a hydroprocessing step carried out in one or more slurry reactors, in the presence of hydrogen or a mixture of hydrogen and H2S, obtaining a stream of products in vapor or liquid-vapor phase, and extracting at the bottom, in continuous or discontinuous, a liquid stream containing non-converted products together with the two catalysts of said catalytic system, said liquid stream extracted then being separated into a clarified primary stream containing the first catalyst, which is at least partially recycled to the hydroprocessing step, and a stream rich in the second catalyst, which is regenerated in a regeneration step and at least partially recycled to the hydroprocessing step.

    摘要： The invention relates to a method for revamping a conventional refinery of mineral oils into a new biorefinery, wherein said biorefinery is characterized by a production scheme which enables the treatment of raw materials of a biological origin for the production of biofuels with a high productivity and reduced hydrogen consumption. Said method allows the re-use of existing plants, enabling, in particular, the revamping of a refinery containing a system comprising two hydrodesulfurization units, U1 and U2, into a biorefinery comprising a unit for the production of hydrocarbon fractions from mixtures of a biological origin, containing fatty acid esters, by hydrolysis of the same (ID), hydrodeoxygenation and isomerization. Each of said hydrodesulfurization units U1 and U2 comprises: a hydrodesulfurization reactor, (Al) 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, a treatment unit of acid gases downstream of the reactor, containing an absorber (B) for H2S, said unit called Tl in the unit U1 and T2 in the unit U2, and the method of the present invention comprises: installing a unit ID, comprising a hydrolysis reactor Rid, upstream of the unit U1, installing a connection line LD between the unit ID and the unit U1, installing a line L between the units U1 and U2 which connects them in series, possibly installing a product recycling line for the unit U1 and possibly installing a recycling line 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 a hydroisomerization catalyst, installing a by-pass line X of the treatment unit of acid gases T2 of the unit U2, substituting the absorber (B), in the unit for the treatment of acid gases T1, with a specific absorber for CO2 and H2S. The new operational configuration, obtained with the method object of the present invention, allows materials of a biological origin to be converted to biofuels, controlling the corrosion phenomena, reducing the hydrogen consumption, increasing the productivity and recovering glycerine, as by-product, that can be commercially exploited.
