The IntegratedHydroprocessing and Catalytic Cracking (IHCC) technology developed by RIPP passedappraisement recently. The commercial trial in Yangzi Petrochemical showed 10%increase of liquid productyield, 20% and 40% decrease of coke yield and dry gas yield respectively. Participatingexperts agreed that this technology would have significant influence on heavyand inferior crudes processing, deep and high-efficient conversion of heavy oilas well as light oil products yield increase.
