The present invention deals with activation and start-up procedures of catalysts for the deep HDS of middle distillates for producing ultra low sulfur diesel (ULSD), consisting of two in situ activation stages: at stage 1, TGA is applied, and at stage 2, DMDS is used; kerosene is the transport means at these stages, which are carried out under given temperature and pressure conditions, and feedstock and hydrogen flows at established times. After the activation of the catalyst in situ, the stabilization stage takes place under selected temperature and pressure conditions, feedstock and hydrogen flow at established times, with which the stabilization of the highly dispersed metallic sulfides is achieved and, in this way, the activity of the catalysts removing contaminants for the production of ULSD is increased.

Process for the activation and start-up of catalysts for deep hydrodesulfurization of middle distillates

The invention relates to a method of preparing a catalytic composition comprising at least one non-noble metal from group VIII and at least one metal from group VIB of the periodic table. The invention also relates to the catalytic composition thus produced, which has a high specific activity in reactions involving the hydroprocessing of light and intermediate fractions, preferably in reactions involving the hydrotreatment of hydrocarbon streams, including hydrodesulphurization (HDS), hydrodenitrogenation (HDN) and hydro-dearomatization (HDA).

Process for preparing a catalytic composition for the hydroconversion of petroleum fractions

The present invention relates to the novel catalytic composition having a high specific activity in reactions involving hydroprocessing of light and intermediate petroleum fractions, and preferably in hydrodesulphurization and hydrodenitrogenation reactions. The inventive catalyst contains at least one element of a non-noble metal from group VIII, at least one element from group VIB and, optionally, a group one element of the VA group, which are deposited on a novel catalytic support comprising of an inorganic metal oxide from group IVB, consisting of an (1D) one-dimensional nanostructured material having nanofibers and/or nanotube morphology with high specific surface area of between 10 and 500 m/g.

Nanomaterials of the JT phase of the titanium oxide TiO, where 0&#x2266;x&#x2266;1 having as a building block a crystalline structure with an orthorhombic symmetry and described by at least one of the space groups 59 Pmmn, 63 Amma, 71 Immm or 63 Bmmb. These nanomaterials are in the form of nanofibers, nanowires, nanorods, nanoscrolls and/or nanotubes. The nanomaterials are obtained from a hydrogen titanate and/or a mixed sodium and hydrogen titanate precursor compound that is isostructural to the JT crystalline structure. The titanates are the hydrogenated, the protonated, the hydrated and/or the alkalinized phases of the JT crystalline phase that are obtained from titanium compounds such as titanium oxide with an anatase crystalline structure, amorphous titanium oxide, and titanium oxide with a rutile crystalline structure, and/or directly from the rutile mineral and/or from ilmenite. The titanates are submitted to dynamic thermal treatment in an inert, oxidizing or reducing atmosphere to produce the JT phase of the TiO, where 0&#x2266;x&#x2266;1 with an orthorhombic structure.
