Integrated hydrotreating and hydrocracking with continuous hydrotreating catalyst regeneration
An integrated hydrotreating and hydrocracking process includes contacting a hydrocarbon oil stream with a hydrogen stream and a hydrotreating catalyst in a moving-bed hydrotreating reactor, thereby producing a hydrocarbon product stream and a spent hydrotreating catalyst; contacting the hydrocarbon product stream with a second hydrogen stream and a hydrocracking catalyst in a hydrocracking reactor, thereby producing a hydrocracked hydrocarbon product stream; processing the spent hydrotreating catalyst to produce regenerated hydrotreating catalyst; and recycling the regenerated hydrotreating catalyst to the moving-bed hydrotreating reactor.

TWO-PHASE MOVING BED REACTOR UTILIZING HYDROGEN-ENRICHED FEED
A process for conversion of a liquid hydrocarbon feedstock in a moving bed hydroprocessing reactor is provided in which (a) hydrogen gas is dissolved in the liquid feedstock and (b) the mixture is flashed to remove and recover any light components, leaving a hydrogen-enriched feedstock. A homogeneous and/or heterogeneous catalyst is added to the feedstock upstream of the moving bed hydroprocessing rector.
MOVING BED REACTOR FOR PROCESSING THREE PHASE FLOWS
A moving bed reactor is provided that can allow facilitate performing a reaction involving a three-phase flow under co-axial flow conditions for the solid and liquid portions of the three phase flow, while the gas portion of the three-phase flow is exposed to the solids under radial flow conditions. Methods for using such a moving bed reactor to perform a reaction, such as upgrading of a feed to distillate products, are also provided.

Use of polymers as heterogeneous hydrogen donors in the upgrading of heavy and extra-heavy crudes
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.
