    摘要： The present invention relates to the process for preparing improved solid hydrogen transfer agents obtained from a polymer with units containing the structure of naphthalene, phenanthrene or anthracene, which exhibit activity as hydrogen transfer agents in any chemical reduction reaction involving the breaking of double bonds and in treatment, hydrotreatment and hydrodisintegration reactions of heavy and extra-heavy crude oils and of cuts and currents derived therefrom. These improved solid hydrogen transfer agents can be supported and not supported on metal oxides such as boehmite, alumina, silica, titania, kaolin and/or mixture thereof, in the presence of reducing agents such as hydrogen, methane, or natural gas. In addition, the application of these improved solid hydrogen transfer agents obtained from a polymer with units containing the structure of naphthalene, phenanthrene or anthracene, it allows to improve properties of the crudes such as viscosity, decrease in the formation of coke, increase in the yield of distillates and in API gravity. These hydrogen transfer agents, being solid, can be reused and recovered from the reaction medium; they also have a thermal stability such that it can carry out reactions at temperatures up to 450° C.

    摘要： 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. The In-Situ Cleaning procedure to reactivate deactivated hydrotreating catalysts used to partially remove the carbon and increase the active phase of molybdenum di-sulphide, and also retrieve specific area, and hydrogenation sites that promote higher hydrodesulfurization activity of gasoil after this treatment.
