Abstract: Reactant-active phase Optimization & Cost-effective Key Technology，ROCKET, was created through the analysis of the key factors affecting catalyst activity and stability. The highly active RS-2100 (NiMo) and RS-2200 (CoMo) catalysts with a high cost performance ratio were developed based on ROCKET technology and characterized by high hydrodesulfurization (HDS) activity, excellent stability, low bulk density and low cost. Industrial application results show that the RS-2100 and RS-2200 catalysts are capable of long-term continuous and stable operation for production of ultra-low sulfur diesel (ULSD) meeting National V emission standard, indicating the strong market competitiveness of the catalysts.
