METHOD FOR REDUCING ASPHALTENE

WIPO Patent Application WO/2019/245094

A1

A method for reducing asphaltene is provided. The method for reducing asphaltene comprises the steps of: feeding, into a reactor, an asphaltene-containing material, a solvent, and a metal oxide precursor; and performing deasphalting by causing the reactor to change to a supercritical condition.
