Process for the hydroconversion of heavy hydrocarbon oils with reduced hydrogen consumption operating at full conversion
In the hydroconversion processes of heavy hydrocarbon oils, in which the hydrogen is introduced at the reactor base by bubbling, the low diffusion rate of hydrogen, from the gas phase to the reaction liquid, limits the degree of conversion. The process circumvents the obstacle of the limited amount of reactant hydrogen by using a slurry bubble column reactor which reduces the formation of light hydrocarbon products, and therefore the hydrogen required for the hydroconversion, allowing to operate at full conversion.
Process for determining presence of mesophase in slurry hydrocracking
A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The slurry hydrocracking reaction can be controlled by measuring the production of mesophase using X-ray diffraction. Upon a mesophase yield fraction reaching a predetermined level, reaction conditions should be moderated to avoid excessive coke production.

Method of making hydrocarbon soluble metal compositions
The present invention relates to a method of making of hydrocarbon soluble metal composition comprising of one or more metals of group VIB of the periodic table, wherein the metal having 4+ oxidation state predominantly forms highly active metal sulfide catalyst for hydro-conversion of heavy oil feedstocks in liquid phase. More particularly, present invention relates to a hydrocarbon soluble metal composition comprising of reaction products of a metal source, a lipophilic phenolic acid, a surfactant and an organophosphorus compound. The present invention also provides a one-pot process for preparation of the hydrocarbon soluble metal composition comprising reacting a metal source, a lipophilic phenolic acid, a surfactant, an organophosphorus compound and water to obtain a reaction product and drying the reaction product to obtain the hydrocarbon soluble metal composition.
Integrated slurry hydroprocessing and steam pyrolysis of crude oil to produce petrochemicals
An integrated slurry hydroprocessing and steam pyrolosyis process for the production of olefins and aromatic petrochemicals from a crude oil feedstock is provided. Crude oil, a steam pyrolysis residual liquid fraction and slurry reside are combined and treated in a hydroprocessing zone in the presence of hydrogen under conditions effective to produce an effluent having an increased hydrogen content. The effluent is thermally cracked with steam under conditions effective to produce a mixed product stream and steam pyrolysis residual liquid fraction. The mixed product stream is separated and olefins and aromatics are recovered and hydrogen is purified and recycled.

Method and apparatus for upgrading heavy oil
A method and apparatus for upgrading heavy oil is described, having a symbiotic relationship between a cracking reactor vessel and a steam reformer vessel. A first portion of an uncracked residue oil stream from the cracking reactor vessel is passed through a heat exchanger positioned within the steam reformer vessel and back to the cracking reactor vessel, such that a heat exchange takes place which heats the uncracked residue oil stream to promote cracking. A second portion of the uncracked residue oil stream from the cracking reactor vessel is injected directly into the steam reformer vessel. That portion of the uncracked residue oil stream not vaporized in the steam reformer vessel is converted into coke which becomes deposited in a fluidized bed of the steam reformer vessel. The fluidized bed activates steam which reacts with the coke to generate hydrogen. Hydrogen from the steam reformer vessel is directed into the cracking reactor vessel to assist with cracking.
