The present invention relates to a process for the preparation of catalyst(s), comprising the cokneading of boehmite with an active phase comprising a salt of heteropolyanion of Keggin and/or lacunary Keggin and/or substituted lacunary Keggin and/or Anderson and/or Strandberg type, and their mixtures, exhibiting, in its structure, molybdenum and cobalt and/or nickel. The present invention also relates to a process for the hydrotreating and/or hydroconversion of a heavy hydrocarbon feedstock in the presence of catalyst(s) prepared according to said process.

Co-mixed catalyst produced from solutions containing heteropolyanions, method for the production thereof, and use of same in hydroconversion of heavy hydrocarbon feedstock

The present invention relates to a process for deparaffinning a middle distillate feedstock, to convert, in good yield, feedstocks having high pour points into at least one cut having an improved pour point. Said process is performed with at least one catalyst comprising at least one hydro-dehydrogenating phase containing at least one metal from group VIB and at least one metal from group VIII of the Periodic Table of the Elements, and a support comprising at least one IZM-2 zeolite, a zeolite of WI framework type code and at least one binder.

The invention concerns a process for refining a heavy hydrocarbon feed, comprising the following steps: a) a step for selective deasphalting of the heavy hydrocarbon feed by single-step liquid/liquid extraction in an extraction medium, said extraction being carried out using a mixture of at least one polar solvent and at least one apolar solvent, in order to obtain an asphalt phase and a deasphalted oil phase DAO, the proportions of said polar solvent and said apolar solvent in the solvent mixture being adjusted as a function of the properties of the feed and the desired asphalt yield, said deasphalting step being carried out under subcritical conditions for the solvent mixture;b) a step for hydrotreatment of at least a portion of the deasphalted oil phase DAO obtained from step a);c) optionally, a step for catalytic cracking of at least a portion of the effluent obtained from step b).

The present invention describes a distributor plate adapted to co-current downflow flows of gas and of liquid, more particularly in the 'trickle' mode, said distributor plate integrating a filtration function separate from the distribution function.

Filtering distributor plate for supplying a fixed bed reactor having a co-current downflow of gas and liquid for the treatment of heavy clogging feeds

Process for hydrotreating a heavy hydrocarbon fraction using a system of switchable fixed bed guard zones each containing at least one catalyst bed including at least one step during which the flow of feed supplied to the first guard zone brought into contact with the feed is partly displaced to the next guard zone downstream, preferably progressively.

Process for hydrotreating heavy hydrocarbon feeds with switchable reactors including at least one step of progressive switching

A catalyst usable in hydrotreatment processes: an alumina-based amorphous support, phosphorus, a C1-C4 dialkyl succinate, acetic acid and a hydro-dehydrogenizing function of at least one group VIII element and at least one group VIB element, preferably made up of cobalt and molybdenum, a catalyst whose Raman spectrum comprises the most intense bands characteristic of the Keggin heteropolyanions (974 and/or 990 cm), C1-C4 dialkyl succinate and acetic acid (896 cm). Preferably, the dialkyl succinate concerned is dimethyl succinate and its main band is at 853 cm.

Catalyst that can be used in hydrotreatment, comprising metals of groups VIII and VIB, and preparation with acetic acid and dialkyl succinate C1-C4

The present invention describes a method for measuring the concentrations of species present at one point of a separation unit functioning in simulated moving bed mode (SMB), using an immersing probe located at one point in the unit or on one of the streams entering or leaving said unit, and a thermocouple located in the vicinity of the immersing probe, in which a Raman spectrum obtained using a laser source functioning at a wavelength of 785 nm is utilized.
