A device for the descending flow of a hydrocarbon-containing liquid containing solid particles at the bottom of an item of equipment () and a process for the conversion of hydrocarbon-containing feedstocks implementing said device.

Device comprising lateral injections of liquid for limiting the phenomena of solid deposits in items of equipment with a conical bottom

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&#xb0; 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&#xb0; 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. 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&#xb0; 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.

Method for converting residues incorporating deep hydroconversion steps and a deasphalting step

A vessel for the downflow of a preferably hydrocarbon liquid, containing solid particles: a bottom comprising a cylindrical upper part (), a lower part () with a decreasing cross section and a varying angle of inclination &#x3b1; with respect to the vertical axis (Z), and an outlet pipe (); injections () and () of recirculated and/or of makeup liquid into the lower and upper parts respectively; injections () inclined with respect to the tangent to the wall of the lower part at the injection point by an angle &#x3b2;in the vertical plane (xz) and by an angle &#x3b2;in the horizontal plane (xy); injections () are inclined with respect to the wall of the upper part by an angle &#x3b8;in the vertical plane (xz) and by an angle &#x3b8;in the horizontal plane (xy).

Vessel comprising a bottom of decreasing cross section and variable angle of inclination, with lateral injections of liquid to limit fouling

The present invention relates to a process for hydroconversion of a heavy hydrocarbon feedstock in the presence of hydrogen, at least one supported solid catalyst and at least one dispersed solid catalyst obtained from at least one salt of a heteropolyanion combining molybdenum and at least one metal selected from cobalt and nickel in a Strandberg, Keggin, lacunary Keggin or substituted lacunary Keggin structure.

Process for hydroconversion of heavy hydrocarbon feedstock in hybrid reactor

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&#xb0; 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.

Method for converting heavy hydrocarbon feedstocks with recycling of a deasphalted oil

The present invention relates to a three-phase reactor for the reaction of a hydrocarbon feedstock with hydrogen and to a hydroconversion process, for example of H-Oil&#x2122; type, employing it, comprising a chamber with an upper end and a gas/liquid separation device comprising:

Three-phase reactor with recycle cup of decreasing section and of variable angle of inclination

Downflow hydrocarbon liquid device having a cylindrical upper part, a frustoconical lower part, an outlet pipe and a vortex-limiting system or vortex-breaker, with at least one flat blade and a hydrocarbon feedstocks conversion method employing the device.
