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 1):
A process for preparing improved solid hydrogen transfer agents for the processing of heavy or extra-heavy crudes or residues, characterized by it comprises the following steps: a) preparing the raw materials by grinding in a porcelain mortar AlO (OH) (Boehmite) SiO2, Al2O3, kaolin, preferably the Boehmite and a polymer with units containing the structure of naphthalene or phenanthrene or anthracene, preferably the naphthalene when sieving these raw materials through a mesh 165 (0.089 mm); b) prepare the physical mixture of the materials indicated in part a), wherein, to the grinded and sieved Boehmite, distilled water is added and mixed until it forms a paste, later, it is peptized by adding an aqueous solution of nitric acid to the 5% by volume to form a gel; c) mixing the gel obtained with a polymer of units containing the naphthalene structure, until obtaining a material with adequate properties for extruding; d) extrude the physical mixture AlO (OH)-polymer resin when the paste obtained in part b) is placed in a mechanical extrusion system at a constant speed and receive the extrudates in metal trays; e) drying the extrudates for 12 to 24 hours at room temperature; and, f) preparing the solid hydrogen transfer agents for activation by cutting them to the length in the range of [0.5-1.2 cm] and leaving them in an oven at 90-120\u00b0 C. for 12 to 24 hours;) loading the material obtained in part f) in a continuous flow reactor where a hydrogen flow of 100-500 ml/min, a pressure of 40 to 70 kg/cm2 and a temperature between 100 and 500\u00b0 C. is passed for a time of 10 to 24 hours.
