The present application relates to a process for treating gasoline, comprising the steps of: contacting a gasoline feedstock with a mixed catalyst and subjecting it to desulfurization and aromatization in the presence of hydrogen to obtain a desulfurization-aromatization product; optionally, splitting the resulting desulfurization-aromatization product into a light gasoline fraction and a heavy gasoline fraction; and, optionally, subjecting the resulting light gasoline fraction to etherification to obtain an etherified oil; wherein the mixed catalyst comprises an adsorption desulfurization catalyst and an aromatization catalyst. The process of the present application is capable of reducing the sulfur and olefin content of gasoline and at the same time increasing the octane number of the gasoline while maintaining a high yield of gasoline.

A catalyst structure includes a porous support structure, where the support structure includes an aluminosilicate material and any two or more metals loaded in the porous support structure selected from Ga, Ag, Mo, Zn, Co and Ce. The catalyst structure is used in a hydrocarbon upgrading process that is conducted in the presence of methane, nitrogen or hydrogen.

The specification discloses a highly macroporous catalyst for hydroprocessing and hydroconversion of heavy hydrocarbon feedstocks. The high macroporosity catalyst incudes an inorganic oxide, molybdenum, and nickel components. It has a pore structure such that at least 18% of its total pore volume is in pores of a diameter greater than 5,000 angstroms and at least 25% of its total pore volume is in pores of a diameter greater than 1,000 angstroms. Preferably, the pore structure is bimodal. The catalyst is made by co-mulling the catalytic components with a high molecular weight polyacrylamide followed by forming the co-mulled mixture into a particle or an extrudate. The particle or extrudate is dried and calcined under controlled calcination temperature conditions to yield a calcined particle or extrudate of the high macroporosity catalyst composition.

The present invention is related to the application of solid polymers or copolymers prepared from monomers having in their structure a polycyclic aromatic ring, an aromatic ring of the type of naphthalene, or polyesters, polyethers, polyamides or polyvynil derivatives having naphthalene units in their structure, in the hydrotreatment or hydrocracking of heavy hydrocarbons, such as heavy or extra-heavy crude oils or residues from the distillation of petroleum; these polymers or copolymers may be supported, anchored or in a physical mixture with metallic oxides such as alumina, silica, titania or kaolin, and they have an application as heterogeneous hydrogen donors in reactions of hydrotreatment or hydrocracking of heavy or extra-heavy crude oils, residues from the distillation of petroleum and cuts and streams deived from this distillation. These solid polymers or copolymers operate in the presence of hydrogen or methane-rich gas. These hydrogen donor polymers, being solid, may be recovered from the reaction mixture to be reused and have a thermal stability that allows for their use in reactions at temperatures above 450 C. These heterogeneous hydrogen donors improve the physical properties of crude oils, such as API gravity, viscosity, and distillates yield, inhibiting the formation of coke.

Processes and systems for upgrading resid hydrocarbon feeds are disclosed. The process system may operate in two different operating modes, maximum conversion and maximum quality effluent. The process system may be reversibly transitioned between the different operating modes. The system has the ability to reversibly transition between the two modes without shutting down the system or losing production.
