Abstract:
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.

Claim (Index 3):
A process for the improvement of heavy, extra-heavy crudes or residua according to  claim 2 , comprising: a) contacting the improved solid hydrogen transfer agent with a heavy, extra-heavy crude or residue of 9 to 12\u00b0 API and viscosity of 5.968 cSt measured at 37.8\u00b0 C., at a temperature of 350 to 450\u00b0 C., at a pressure of 50 to 100 kg/cm 2 , where the hydrogen transfer reactions are carried out in the presence of a reducing agent, such as hydrogen, methane or natural gas; b) obtaining heavy or extra-heavy crudes or residues with an increase in API gravity from 3 to 6 units, a decrease in viscosity up to 100 cSt determined at 37.8\u00b0 C. and an increase in the yield of distillates, naphtha and intermediate distillates, determined by TBP (True Boiling Point), mainly between 10-20% by volume.
