octane number is an important indicator reflecting the combustion performance of gasoline. To accomplish octane number modeling and its control variables optimization effectively, this paper proposes a novel control method MDR-NSGA-Ⅱ which combines the multi-level dimension reduction（MDR） and non-dominated sorting genetic algorithm Ⅱ（NSGA-Ⅱ）. Firstly,based on the chemical data, the MDR method is used to select the control variables to obtain the main control variables. The MDR integrates the advantages of the distance correlation coefficient, the sparse representation method, and a machine learning fusion algorithm RF-XGBoost combining random forest（RF） and eXtreme gradient boosting（XGBoost）. Secondly, the main control variables are controlled and optimized using NSGA-Ⅱ. Specially, an octane number loss model based on Elman neural network is established as a prediction model for the solution of NSGA-Ⅱ. Finally, the results of MDR-NSGA-Ⅱ are analyzed and evaluated, and it can be concluded that the proposed method can accomplish the octane modeling and its optimal control well.

The maximizing iso-paraffins （MIP） developed by RIPP has improved gasoline quality to meet the demand of motor gasoline specification. A concept that two different reaction zones include cracking zone and conversion zone is proposed as the fundamental of MIP by research on fluid catalytic cracking （FCC） reaction chemistry. Based on the concept, the MIP process is featured by applying a novel sequential two-zone riser in conjunction with proprietary catalyst and engineering technique. The developed MIP process can not only improve gasoline yield or gasoline plus propylene yields but also produce gasoline with a higher content of iso- paraffins and a lower content of sulfur. Aminimum octane number loss is achieved when MIP gasoline is treated by downstream desulfurization technology （RSDS/S Zorb）. The combination of MIP and RSDS/S Zorb processes creates a very competitive route, which is different from the technical route used by other developed countries, to upgrade the quality of motor gasoline with the lowest economic costs in China. In just one decade, the processing capacity of MIP units has accounted for about 60% of the domestic total processing capacity of FCC units. The MIP process is gradually becoming a new generation of FCC technology.

PetroChina Jinxi Petrochemical Branch Company has applied the MIP technology in its RFCC unit to maximize the light distillate while using the paraffinic gas oil blended with resid and the coker gasoil as the feedstocks. The outcome of the unit operating according to the MIP mode has revealed that the olefin content in the stabilized gasoline could be reduced to less than 35 % with its research octane number equivalent to and its motor octane number slightly higher than the octane rating of the FCC naphtha obtained by the former operational mode of the RFCC unit, and the diesel yield could reach over 30 m%. The total liquid yield （LPG＋gasoline＋diesel） of the unit operating according to the MIP mode was by over 1.5 percentage points higher than that achieved in the former RFCC unit.

This article refers to major measures for reducing olefin content of automotive gasoline and the effect after adoption of these measures. The key for reducing olefin content in China's automotive gasoline pool is to reduce the olefin content of FCC naphtha. The domestic refiners apply the olefinreducing catalyst to decrease the olefin content of FCC gasoline as a convenient and cheap means to meet the national standard for automotive gasoline at the present phase. Furthermore, the novel domestic FCC reaction processes, such as the MIP, MGD, FDFCC and other processes can also apparently reduce olefin content in FCC gasoline. In order to further reduce the olefin content in gasoline to meet more stringent standard for automotive gasoline, Chinese refiners should optimize the processing scheme while aggressively disseminating hydrogenation process along with development of catalytic reforming,alkylation, etherification and other processes to completely change the simplistic composition of domestic gasoline pool.

This article refers to the application of DOCO olefin-reducing catalyst developed by RIPP and manufactured by the Catalyst Factory of Changling Refining and Chemical Company in the 1.4 Mt/a RFCCU at Daqing Petrochemical Company. Results of operation over two months had revealed that this catalyst had good olefin-reducing ability and heavy oil converting ability adapted to paraffinic feedstock. The gasoline olefin yield had been reduced to 36.1 v% from 54.2 v% with gasoline RON rating decreased by 1.4 units. The induction period of gasoline had significantly increased to 952 mm, while the coke yield was increased by 0.05 percentage point with light oil yield dropping by only 0.02 percentage point. The FCC product distribution is favorable.

The evaluation testing of propylene promoter LCC-A was carried out in a bench scale fixed fluidized bed reactor and a pilot scale riser. The commercial application experiments on this promoter were conducted in the #3 RFCCU at Dalian Petrochemical Co. and #1 integrated refining unit at Shanghai Petro- chemical Co. The test results have shown that after adding 5%—6% of the promoter LCC-A to the main FCC catalyst the propylene yield and selectivity were raised obviously. The octane rating of FCC gasoline was increased by more than one unit; which could alleviate the negative impact of octane number decline resulted from reduction of olefin content in FCC naphtha along with an increased propylene yield to meet the urgent market demand for propylene. The test results achieved at Shanghai Petrochemical Company have revealed that when the addition of the LCC-A promoter reached 5% of the catalyst inventory, its performance could be on a par with that of the overseas promoter OlefinsMax.

This articles refers to the development of the technology for hydrodesulfurization (HDS) and aromatization of FCC naphtha This technology adopts a catalyst with aromatization performance, which does not reduce the octane rating of gasoline in the course of HDS of FCC naphtha. Experimental results have shown that the sulfur removal rate of FCC naphtha could reach over 85%, with the RON of gasoline increased by 0.2-0.6 units, the MON increased by 1.3-1.8 units and the antiknock index of the gasoline increased by around one unit. The total C5+ liquid yield was over 95%. The activity of regenerated catalyst could be restored to be equal to that of fresh one after coke burning on the spent catalyst.
