  • Publication number: 20240141239
    Abstract: The present disclosure involves application of heterogeneous hydrogen donors (DHH) or solid hydrogen transfer agents (SHTA) prepared from a polymer with units containing the structure of naphthalene, phenanthrene or anthracene, which can be supported, anchored or in physical mixture with metal oxides such as alumina, silica, titania or kaolin and/or mixture of them, to be used in beds combined with an ULSD or non-ULSD HDS catalyst, to obtain ultra-low sulfur diesel in cuts and/or streams derived from petroleum and/or a mixture thereof, such as SRGO, kerosine, jet fuel, naphtha, etc. The SHTA of the present disclosure provide an additional amount of hydrogen atoms facilitating the removal of refractory sulfur compounds in the HDS process.

  • Patent number: 11111443
    Abstract: The present invention deals with a process for catalytic cracking of hydrocarbons comprising vacuum gas oil, hydrotreated vacuum gas oil, unconventional light crude oil, preferably unconventional light crude oil type shale/tight oil and its blends with conventional vacuum gas oil, in order to generate products of major commercial value in the field of fuels, getting improved gasoline and coke yield, as well as the procedure for the preparation of a catalyst with essential physical properties of density and particle size to uphold it in a fluidized bed under the operation conditions in the catalyst evaluation unit at micro level, wherein the catalyst particles achieve a catalytic performance similar to fluidized microspheres in a reactor, without appreciable generation of fine particles.

  • Patent number: 10974229
    Abstract: According to this invention, a Ni—Mo—W trimetallic catalyst supported on porous alumina is obtained that shows very high activity for hydrotreating (HDT) of gasoils, particularly deep hydrodesulfurization (HDS) and hydrodesnitrogenation (HDN) of straight run gasoil in conditions of moderate pressure. When the catalyst is applied to HDT of diesel, the NiMoW catalyst exhibits high catalytic activity. The content of sulfur and nitrogen in the resulting diesel can be reduced from 13,200 to 10 ppm and nitrogen from 360 ppm to less than 1 ppm, under moderate pressure, temperature and space-velocity (LHSV) similar to those of an industrial unit.

  • Patent number: 10858594
    Abstract: The present disclosure relates to a process for the hydrodeoxygenation of vegetable oils or animal fats to produce green diesel, which comprises contacting the vegetable oil or animal fat with a Nickel-Molybdenum or Cobalt-Molybdenum catalyst supported on alumina-titania or titania, respectively; in a fixed bed reactor in the presence of hydrogen. The process involves hydrocracking, hydrogenation, decarboxylation, decarbonylation, carried out in a fixed bed reactor at temperature of about 270° C. to about 360° C., pressure of about 40 kgf/cm2 to about 60 kgf/cm2, liquid hourly space velocity (LHSV) between about 0.8 h?1 to about 3.0 h?1, and H2/oil ratio of about 2,700 ft3/bbl to about 7,000 ft3/bbl, that allows to obtain a conversion up to 99% and up to 92.7% yield on green diesel.

  • Patent number: 10512906
    Abstract: The present invention is an in-situ cleaning procedure for the recovery of catalytic activity of a based alumina HDS catalyst, molybdenum, nickel coated coke and contaminants and it has an HDS activity seriously diminished. The catalyst under study had between 13 and 18 wt % total carbon. Reformate, half the total volume, industrial toluene=35 volume % and Iso-propylic alcohol, 15 volume %, in order to reactivate a deactivated catalyst, a solvent mixture with the following volumetric ratio is prepared. Or it can also be used only reformate (100% volume). The solvent mixture is passed using a LHSV of 2 hr?1 for 72 hours at 50° C. or also using a recirculating three 24-hour cycles at 50° C. Option lasts 24 hours pure reformate LHSV=2h?1 to 50° C. The washed catalyst is fed back to the load reaction conditions maintained for 36 hours at 340° C., to initiate HDS activity balances. During this treatment oxides of molybdenum and nickel in the active phase are re-sulfided by increasing the HDS activity.
