The U.S.Tier 22222 regulation requires a reduction from average 340ppm to 30ppm from 2004 to 2008. Recently significant progress has been made in effective high sulfur removal, such as post treatment of FCC gasoline by selective hydrotreating, S Zorb sulfur removal technology, OATS process etc. The sulfur content of FCC gasoline can be deceased to less than 10ppm. With regard to gasoline pool composition in China, it is very important to look for effective desulfurization processes that are simple, straightforward, with less hydrogen consumption. Post-treatment of FCC gasoline is a preferred option. From the point of view of comprehensive utilization, alkylation, polymerization, isomerisation etc. can be added to desulfurization process to meet the requirement of ultra low sulfur, premium. 展开更多

On the basis of the reaction rules and its influencing factors of sulfur compounds in MIP naphtha, a correlation model for describing the correlation between mass fraction of sulfur in MIP naphtha, mass fraction of sulfur in feedstock and volume fraction of olefin in naphtha was developed and the model's parameters were estimated. The residual error distribution and statistical study showed that the developed model was reasonable and reliable and able to predict the mass fraction of sulfur compounds in naphtha. The correlation model can provide theoretical guidance and operation base for adjusting process parameters to produce EURO IV gasoline by the MIP units. The model was validated by its application on the MIP unit of Qingdao Refining & Chemical Company. On this unit, the tail oil with low sulfur content obtained via hydrotreating gas oil was used as the feedstock and the olefin content of naphtha was reduced by promoting hydrogen transfer reaction through adjustment of process parameters. Thus, EURO IV clean gasoline was manufactured by this MIP unit. 展开更多

The sulfur-reducing functional component the Lewis acid-base pair compound and associated active zeolite component were developed to prepare the RFCC catalyst DOS for reducing sulfur content in gasoline. The results of catalyst evaluation have revealed that the Lewis acid-base pair compound developed hereby could enhance the conversion of macromolecular sulfur compounds by the catalyst to promote the proceeding of desulfurization reactions, and the synergetic action of the selected zeolite and the Lewis acid-base pair compound could definitely reduce the olefins and sulfur contents in gasoline. The heavy oil conversion capability of the catalyst DOS thus developed was higher coupled with an enhanced resistance to heavy metals contamination to reduce the sulfur content in gasoline by over 20%. The commercial application of this catalyst at the SINOPEC Jiujiang Branch Company has revealed that compared to the GRV-C catalyst the oil slurry yield obtained by the catalyst DOS was reduced along with an improved coke selectivity, an increased total liquid yield, and a decreased olefin content in gasoline. The ratio of sulfur in gasoline/sulfur in feed oil could be reduced by 20.3 m%. 展开更多

Worldwide environment has resulted in a limit on the sulfur content of gasoline.It is urgent to investigate the desulfurization of gasoline.The polydimethylsiloxane(PDMS)/polyetherimide(PEI)composite membranes were prepared by casting a PDMS solution onto porous PEI substrates and characterized by scanning electron microscope(SEM).The membranes were used for sulfur removal from gasoline by pervaporation.The effects of feed temperature,sulfur content in the feed and PDMS layer thickness on membrane performance were investigated,and an activation energy of permeation was obtained.Experimental results indicated that higher feed temperature yielded higher total flux and lower sulfur enrichment factor.The total flux varied little with the increase of sulfur content in the feed,but the sulfur enrichment factor first increased with the amount of thiophene added into the gasoline,and then the variation was little.The increase of PDMS layer thickness resulted in a smaller flux but a larger sulfur enrichment factor.The result indicates that the PDMS/PEI composite membranes are promising for desulfurization by pervaporation. 展开更多

The research and development of the CGP-2 catalyst, which was used in the MIP-CGP process for reducing the olefin and sulfur contents of FCC naphtha and enhancing the propylene yield, were introduced. A specific type of metal compound was added into the matrix to provide active centers for reactions including catalytic conversion and selective adsorption of sulfur containing compounds. The CGP-2 catalyst possessed excellent hydrothermal stability to meet the requirements of the 2rid reaction zone of the MIP-CGP process. The commercial test of the said catalyst at the SINOPEC Cangzhou refinery showed that in comparison with the base case (using the CGP-1Z catalyst) the CGP-2 catalyst could reduce the sulfur content of FCC naphtha by 30.32% and increase the propylene yield along with good coke selectivity. Thus, the naphtha produced by the MIP-CGP process at the Cangzhou refinery can meet the new gasoline standard enforced in July 2005. 展开更多

Reduction of sulfur content in FCC gasoline was studied in a fixed fluid bed (FFB) unit by using metal-modified LV-23 FCC catalyst. The results showed that the sulfur content in FCC gasoline could be reduced with LV-23 catalyst modified with zinc, palladium, zinc-palladium, zinc-cobalt, and zinc-nickel. Among these metals or metal combinations, palladium-containing catalyst was the most effective. Desulfurization of the heavy fraction of FCC gasoline was more effective than full-range gasoline under the same conditions with palladium-containing catalysts. A high reaction temperature was favorable to desulfurization, but it would reduce the yield of liquid product. After desulfurization reaction, the olefin content of product gasoline decreased while the aromatic and iso-alkane contents increased. Removal of thiophene and benzothiophene is higher. 展开更多

This paper has investigated the influence of gasoline sulfur content on durability of catalytic converter for vehicle exhaust gas. Two gasoline samples with different sulfur contents (equating to 150 μg/g and 50 μg/g of sulfur, respectively) were used to examine the durability and performance of catalytic converter on the bench test. The test results have revealed that in comparison to the influence of sulfur on ageing of catalytic converter the thermal ageing had a more remarkable impact on the performance of catalytic converter, and the performance of catalytic converter could be restored by high-temperature desulfurization process after ageing by the high-sulfur gasoline sample (containing 150 μg/g of sulfur) . 展开更多
