Synergism between Hydrogen Donors and Dispersed Catalysts in Residue Hydrocracking

摘要

Dispersed catalysts hydrogenation processes offer the potential of high conversion with minimal coke yield for the upgrading of heavy oil, however, the severity is limited by excessive coke formation with the activation-lost dispersed catalysts. Some resolutions, for example higher hydrogen pressure, addition of catalysts, have been suggested to deal with coke formation. However, these resolutions have limitations (1).
