Catalytic Aquathermolysis of Heavy Oil With Oil-soluble Multicomponent Acrylic Copolymers Combined With Cu2+

Abstract

A kind of oil-soluble multicomponent acrylic copolymer combined with Cu2+ was synthesized and used for catalytic aquathermolysis of heavy oil. This work showed this copper-bearing copolymer led to 84.52% viscosity reduction for the Lukeqin heavy oil at 513.15 K, and converted 10.01% of the resin fraction and 2.85% of the asphaltene fraction into light oil content. After aquathermolysis with this catalyst, some parts of the long-chain saturated hydrocarbons were broken into short-chain ones, and the aromaticity and aromaticity condensation of the resin and asphaltene decreased.
