The invention relates to a hydrocarbon hydroprocessing catalyst comprising a support based on at least one refractory oxide, at least one metal from group VIII and at least one metal from group VIB. The inventive catalyst is characterized in that it also comprises at least one organic compound having formula (I) or (II): in which each Rrepresents independently an alkyl group at C, an alkenyl group at C, an aryl group at C, a cycloalkyl group at C, an alkylaryl or arylalkyl group at C, or the two Rgroups together form a divalent group at C, and Rrepresents an alkylene group at C, an arylene group at C, a cycloalkylene group at C, or a combination of same. The invention also relates to a method of preparing one such catalyst and to the use thereof for hydroprocessing or hydrocracking.

Hydroprocessing catalyst, preparation method thereof and use of same

The invention relates to a hydrocarbon hydroprocessing catalyst comprising a support based on at least one refractory oxide, at least one metal from group VIII and at least one metal from group VIB. The inventive catalyst is characterized in that it also comprises at least one organic compound having formula (I) or (II) in which each Rrepresents independently an alkyl group at C, an alkenyl group at C, an aryl group at C, a cycloalkyl group at C, an alkylaryl or arylalkyl group at C, or the two Rgroups together form a divalent group at C, and Rrepresents an alkylene group at C, an arylene group at C, a cycloalkylene group at C, or a combination of same. The invention also relates to a method of preparing one such catalyst and to the use thereof for hydroprocessing or hydrocracking. 

The invention relates to a hydroconversion catalyst, which comprises a refractory oxide support, at least one metal selected from group VIII and at least one metal selected from group VIB and which is characterized in that it has at least one organic compound containing at least one oxime group of formula (I)&#x3e;C&#x2550;NOR, in which Ris selected among hydrogen and alkyl, allyl, aryl, alkylene or cycloaliphatic groups, and combinations thereof, these groups being able to be substituted by at least one electron donor group.

Hydrotreating and/or hydrocracking catalyst of hydrocarbons and preparation thereof

The invention relates to a catalyst for hydroconversion of hydrocarbons, comprising a support made from at least one refractory oxide, at least one group VIII metal and at least one group VIB metal, characterized in further comprising at least one organic compound with at least two thiol functions separated by at least one oxygenated group of formula (I): HS&#x2014;CxHyOz&#x2014;SH (I), where x=1 to 20, preferably 2 to 9 and for example x=6, y=2 to 60, preferably 4 to 12 and z=1 to 10, preferably 1 to 6. The invention further relates to a method for preparation, a method for activation of said catalyst and use of the catalyst for the hydrotreatment and/or hydrocracking of hydrocarbons.

Hydrotreatment catalyst, method for production and use thereof

The invention relates to a hydrocarbon hydroconversion catalyst comprising a carrier based on refractory oxide, a metal of the group VIII, and a metal of the group VIB. Said catalyst is characterised in that it also comprises at least one organic compound selected from the alkene diols of formula (I) wherein Rrepresents a Calkenylene group, preferably Calkenylene, a Carylene group, or a Calkylene-arylene group, and each Rindependently represents a hydrogen atom or a Calkyl group, a Calkenyl group, a Caryl group, a Ccycloalkyl group, or a Calkylaryl or arylalkyl group, or the two groups Rtogether form a divalent Cgroup, the carbonated chain of the Rgroups containing or carrying at least one heteroatom selected from S, N and O. The invention also relates to a method for preparing one such catalyst, and to the use of said catalyst for hydrotreatment or hydroconversion. 

Hydroprocessing catalyst, method for the preparation thereof and use of the same

The invention relates to a process for hydrotreatment of a hydrocarbon feedstock, comprising the step of carrying out in situ or ex situ sulfurization of a catalyst and hydrotreating the hydrocarbon feedstock in the presence of the catalyst wherein at least one sulfur compound may be present in the feedstock; and a process for the purification of a hydrocarbon feedstock, comprising hydrotreating the hydrocarbon feedstock in the presence of a catalyst after sulfurization of the catalyst and oxidizing desulfurization of the hydrotreated feedstock; wherein the catalyst comprises a refractory oxide support, at least one metal of the Group VIII and at least one metal of the Group VI, both in an oxidized form, and at least one sulphone or sulphoxide compound derived from a benzothiophene compound.

Hydrotreating catalyst, process for its preparation and its use in a process for the purification of hydrocarbons

The present invention relates to the use of a catalytic system comprising a metal of group VIII, a metal of group VI, a metal oxide as carrier and suitable quantities of a component selected from a zeolite of the FER type, phosphorous, and a mixture thereof, in upgrading of hydrocarbons boiling in the naphtha range containing sulfur impurities, namely in hydrodesulfurization with contemporaneous skeleton isomerization of olefins contained in said hydrocarbons and/or with reduction of olefins hydrogenation, carried out in a single step.

Process and catalysts for upgrading of hydrocarbons boiling in the naphtha range

The invention relates to a process for the sulphurization of catalysts for the hydrotreating of hydrocarbon feedstocks. According to the invention, a small amount of at least one orthophthalic acid ester is added to the sulphurization agent used to sulphurize the catalyst. The catalysts thus sulphurized prove to be more active than conventionally sulphurized catalysts.
