Method for removing non-solvent asphaltenes from crude oil using solid heteropoly compounds

摘要

A process for removing asphaltenes from an oil feed, comprising the following steps: introducing the oil feed into a reactor, wherein the oil feed comprises a carbonaceous material and asphaltenes; Introducing a heteropolyacid feed into the reactor, wherein the heteropolyacid feed comprises heteropolyacid; Operating the reactor during the reaction time at reaction temperature and reaction pressure to produce the polymerized asphaltene by operating the heteropolyacid to promote the acid catalyzed polymerization reaction of asphaltene, wherein the mixed product is polymerized asphaltene and de- Contains asphalt oil; Introducing the mixed product to a separator at the end of the reaction time, and separating the mixed product in the separator to produce a de-asphalt oil and a waste stream, wherein the de-asphalt oil is compared to the oil feed. Low concentration of sulfur, low concentration of nitrogen, and low concentration of metal.
