The present invention relates to a process for converting a high-boiling hydrocarbon feedstock into lighter boiling hydrocarbon products, said lighter boiling hydrocarbon products being suitable as a feedstock for petrochemicals processes, said converting process comprising the following steps of: feeding a hydrocarbon feedstock having a boiling point of &#x3e;350 deg Celsius to a cascade of hydrocracking unit(s), feeding the bottom stream of a hydrocracking unit as a feedstock for a subsequent hydrocracking unit, wherein the process conditions in each hydrocracking unit(s) are different from each other, in which the hydrocracking conditions from the first to the subsequent hydrocracking unit(s) increase from least severe to most severe, and processing the lighter boiling hydrocarbon products from each hydrocracking unit(s) as a feedstock for one or more petrochemicals processes.

Method for converting a high-boiling hydrocarbon feedstock into lighter boiling hydrocarbon products

A method of this disclosure for removing oxygenates from a hydrocarbon process stream includes passing the hydrocarbon process stream through a vessel containing a mixed metal oxide having an amorphous non-crystalline structure and containing a metal in at least two oxidation states in a hydrate form, the hydrocarbon process stream having a first oxygenate content when entering the vessel and a second lower oxygenate content when exiting the vessel. The hydrocarbon stream may be a gas or a liquid stream.

Processes and systems for synthesizing hydrocarbon products, such as high molecular weight hydrocarbons, olefins or mixtures thereof, from alkyl bromides wherein one or more streams of alkyl bromides may be reacted in sequential or concurrent stages at different temperatures. The catalyst used in the synthesis stages may be the same or different and at least in one instance is chosen to form hydrocarbon products having a significant Cparaffin content. The stages may be conducted in one or more reactors and the catalyst may be deployed in fixed beds or fluidized beds.

Processes and systems for synthesizing alkyl bromides to hydrocarbon products, such as high molecular weight hydrocarbons, olefins or mixtures thereof, wherein one or more streams of alkyl bromides may be synthesized in sequential or concurrent stages at different temperatures. The catalyst used in the synthesis stages may be the same or different and at least in one instance is chosen to form hydrocarbon products having a significant Cparaffin content. The stages may be conducted in one or more reactors and the catalyst may be deployed in fixed beds or fluidized beds.

A process for converting gaseous alkanes to olefins, higher molecular weight hydrocarbons or mixtures thereof wherein a gaseous feed containing alkanes is thermally reacted with a dry bromine vapor to form alkyl bromides and hydrogen bromide. Poly-brominated alkanes present in the alkyl bromides are further reacted with methane over a suitable catalyst to form mono-brominated species. The mixture of alkyl bromides and hydrogen bromide is then reacted over a suitable catalyst at a temperature sufficient to form olefins, higher molecular weight hydrocarbons or mixtures thereof and hydrogen bromide. Various methods are disclosed to remove the hydrogen bromide from the higher molecular weight hydrocarbons, to generate bromine from the hydrogen bromide for use in the process, and to selectively form mono-brominated alkanes in the bromination step.

Processes for converting gaseous alkanes to liquid hydrocarbons

This invention focuses on the specialized catalyst and/or additive for lower FCCU gasoline and diesel blendstock component sulfur content. This invention utilizes a specified ratio of the transition metal oxides of cobalt and molybdenum to accomplish gasoline and diesel blendstock sulfur reduction. This is accomplished by minimizing sulfur compound formation in the FCCU riser. The cobalt and molybdenum oxides in the presence of HS from cracked organic sulfur compounds are converted to metal sulfides. A portion of the overall sulfur reduction in the gasoline and diesel blendstock occurs emitted NOalso is reduced.

A process for converting gaseous alkanes to olefins, higher molecular weight hydrocarbons or mixtures thereof wherein a gaseous feed containing alkanes is reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid is then reacted over a suitable catalyst at a temperature sufficient to form olefins, higher molecular weight hydrocarbons or mixtures thereof and hydrobromic acid vapor. Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons, to generate bromine from the hydrobromic acid for use in the process, and to selectively form monobrominated alkanes in the bromination step.
