Upgrading and visbreaking of super‐heavy oil by catalytic aquathermolysis with aromatic sulfonic copper

摘要: Abstract As one of the important in‐situ upgrading technologies, catalytic aquathermolysis has attracted worldwide interest for heavy oil exploitation recently. Aiming to upgrade and visbreak a kind super‐heavy oil, we have synthesized new type catalyst — aromatic sulfonic copper process it. The experimental results show that, using 0.2 wt.% 25.0 wt.% water at 280 °C 24 h, viscosity sample could be decreased by 95.5%, with 13.72% in conversion content light content. Furthermore, structure group compositions were characterized FT‐IR, GPC, EL, 1 H NMR GC–MS. It is found that improve pyrolysis remove some heteroatoms (S, O N) its molecules, which finally led visbreaking oil. Additionally, view low‐cost synthesis simple preparation this technique, it likely good application prospects.
