Integrated heat treatment for generation of intermediate pitch, removal of asphaltenes, upgrades of crude oil and residue

摘要

A method of producing a mesophase pitch comprises flushing a vessel with at least a substantially inert gas to remove air and oxygen from the vessel; filling the vessel with a hydrocarbon feedstock; Pressurizing to an initial increasing pressure, heating the vessel to a predetermined temperature, and maintaining the vessel at a predetermined temperature for a time operable to upgrade the hydrocarbon feedstock to a product containing mesophase pitch. And steps.
