The invention relates to a catalyst for the transformation of hydrocarbon-containing feedstocks, in particular hydrotreatment, comprising at least one metal of group VIIB and at least one hydro-dehydrogenating metal (of the non-noble metals of group VIII and/or the metals of group VIB, preferably molybdenum or tungsten) and at least one porous matrix, generally of the amorphous oxide or poorly crystallized type. The catalyst also contains silicon, boron, or phosphorus. It can also optionally contain at least one halogen.

Catalyst comprising a zeolite Y globally non-dealuminated and containing boron and/or silicon

The invention provides a catalyst including a support, at least one noble metal from group VIII of the periodic table, silicon as a dopant, optionally boron, optionally at least one group VIB element, optionally phosphorous and optionally at least one halogen. The invention also provides a particular preparation of the catalyst. The invention also concerns the use of this catalyst in the hydrotreatment of hydrocarbon-containing feeds, more particularly its use for hydrogenating aromatic compounds in a gas oil cut.

A catalyst comprising 0.1-99.7% by weight of at least one alumina matrix; 0.1-80% by weight of at least one globally non dealuminated Y zeolite with a lattice parameter of more than 2.438 nm, a global SiO /Al O mole ratio of less than 8, and a framework SiO /Al O mole ratio of less than 21 and more than the global SiO /Al O mole ratio; 0.1-30% by weight of at least one group VIII metal and/or 1-40% by weight of at least one group VIB metal (% oxide); 0.1-20% by weight of at least one promoter element selected from the group formed by boron and silicon (% oxide); 0-20% by weight of at least one group VIIA element; 0-20% by weight of phosphorous (% oxide); 0.1-20% by weight of at least one group VIIB element, useful for hydrocracking processes, especially at low pressures of 7.5 to 11 MPa.

Catalyst containing phosphorous and a process hydrotreatment of petroleum feeds using the catalyst

A process for activation of a hydroconversion catalyst, whereby said catalyst contains at least one metal or element of group VIII, at least one acid element and optionally at least one metal or element of group VI according to which a light petroleum fraction, at least one thionic compound and at least one nitrogenous compound are injected in said catalyst. This process is carried out such that the QS sulfur amount that is injected before the temperature of the catalyst reaches 250&deg; C. is at least equal to half the QS,sulfur amount that is necessary for complete sulfurization of the catalyst.

An IM-5 zeolite that is modified by adding phosphorus that is optionally dealuminified, preferably in aluminosilicic form, and that contains at most 10% by weight of phosphorus, a composition that contains it, its processes for preparation and its application to catalytic cracking of hydrocarbon feedstocks are described.

The invention concerns a process for purifying naphthalene. The process comprises selective hydrotreatment corresponding to hydrodesulphuration and/or hydrodenitrogenation and/or hydrodehydroxylation and/or hydrogenation of olefins while limiting naphthalene hydrogenation. The catalyst used comprises a matrix, at least one group VIII metal, at least one group VI metal and optionally phosphorous. It has a specific surface area of at most 220 m,/g, a pore volume of 0.35-0.7 ml/g and an average pore diameter of over 10 nm. The process is carried out at 150-325&deg; C. at a pressure of 0.1-0.9 MPa, with an HSV of 0.05-10 h,, and a H,/naphthalene ratio of 0.1-1.3 mole/mole. The effluent, freed of H,S, NH,and water, undergoes a naphthalene separation process by distillation or, as is preferable, by crystallisation. Further, recycling the separated tetralin to the hydrotreatment step can substantially increase the naphthalene yield. In this case, the tetralin/naphthalene ratio at the reactor inlet is in the range 0.005 to 0.08.

The invention relates to a process for the sulfurization of hydroconversion catalysts, whereby said catalyst contains at least one element of group VIII of the periodic table and optionally an element of group VI, whereby said metal is present in the oxide state. Said process comprises at least one stage that is carried out in a hydrotreatment zone in the presence of at least one thionic compound and at least one nitrogenous compound. This process is carried out in such a way that before the final sulfurization temperature is reached, at least 130% of the stoichiometric amount of sulfur that is necessary for complete sulfurization of the catalyst is injected in said catalyst.
