After analysing the disadvantages of the traditional residue hydrotreating-catalytic cracking combination process, RIPP has proposed a bi-directional combination technology integrating residue hydrotreating with catalytic cracking called RICP which does not further recycles the FCC heavy cycle oil (HCO) inside the FCC unit and delivers HCO to the residue hydrotreating unit as a diluting oil for the residue that is concurrently subjected to hydrotreating prior to being used as the FCC feed oil. The RICP technology can stimulate residue hydrotreating reactions through utilization of HCO along with an in- creased yield of FCC light distillate, resulting in enhanced petroleum utilization and economic benefits of the refinery.

In order to develop Chinas heavy oil deep processing technology, Fushun Research Institute of Petroleum and Petrochemicals (FRIPP), SINOPEC has developed two series of residue hydrotreating catalysts for vacuum residue and atmospheric residue, which have been commercialized in Qilu Petrochemical Co. and Dalian West Pacific Petrochemical Co. (WEPEC) respectively. On the basis of FRIPPs research, and under the leadership and coordination of SINOPEC headquarters, FRIPP, Luoyang Petrochemical Engineering Company (LPEC), Maoming Petrochemical Co. and Qilu Petrochemical Co. have cooperated and developed the proprietary S RHT packaged technology for sour residue hydrotreating. Using R SHT technology, the 2Mt/a S RHT unit has been constructed in Maoming Petrochemical Co. and successfully put into two year stable operation with considerable economic, social and environmental benefits, which built a record among the operations of the worlds similar units.

The RHT technology and the second generation RHT catalysts were applied in design of an 1.7Mt/a VRDS unit at the SINOPEC Changling Branch Co. The commercial application result demonstrated that the RHT catalysts showed good activity and stability in processing low-sulfur and high-nitrogen residue. The first long period run of unit for processing high Fe and high Ca content residue was achieved. The reasons for excessive pressure drop of R-101 were ascribed to Fe and Ca deposition as well as coke formation.

Qilu Petrochemical Company in order to synchronize the replacement of catalysts in the upflow reactor (UFR) and fixed-bed reactors and achieve the 1.5-year operating cycle of the residue hydrotreating unit has revamped the UFR and optimized catalysts grading. Commercial operation results have revealed that the series of catalysts for residue hydrotreating after optimized grading achieved an operating cycle of 1.5 years with the quality of hydrotreated oil products meeting the requirements for FCC feedstock.

The SHIFT-G technology of inverse catalyst loading is used to optimize the catalyst grading in the residue hydrotreating unit. The results, taken from pilot tests and commercial units, have showed that the optimized catalyst grading system can reasonably distribute the reaction load, effectively improve the prop- erties of hydrotreated products, prolong the operating cycle and promote economic benefits.
