Over 90% sulfur compounds in FCC gasoline are thiophenic sulfur compounds and most of them exist in the high-boiling fraction. A desulfurization method was proposed for the removal of sulfur compounds from FCC gasoline by alkylation of thiophenic sulfur compounds with olefins over solid acid catalyst, and the obtained alkylated thiophenes were concentrated in the heavy fraction of FCC gasoline by rectification. In this paper, the AlCl 3 catalyst supported on a macroporous sulfonic resin CT175 was used for the alkylation of thiophenic sulfur compounds with olefins, and the deactivation mechanism of the catalyst was studied by means of GC-FPD and GC-MS. The AlCl 3-CT175 resin catalyst showed excellent initial catalytic activity for the alkylation of thiophenic sulfur compounds with olefins in FCC gasoline of boiling range of 60~150 ℃, but the catalyst activity decreased greatly after reaction for 20 h. However, when the liquid feedstock comprising benzene, model sulfur compounds (such as thiophene, 2-methylthiophene and 2-ethylthiophene) and isobutylene was used, the AlCl 3-CT175 resin catalyst showed high stability in the 1*!160 h-duration test, and the conversion of thiophene was higher than 95% under WHSV=2.33 h -1 , isobutylene volume velocity of 7.5 ml/min and reaction temperature of 65 ℃. Meanwhile, the effects of diolefin type (such as isoprene, cyclopentadiene and 5-methyl-1,3-cyclopentadiene) and content on the stability of the AlCl 3-CT175 resin catalyst were further investigated, and the catalyst activity decreased rapidly owing to the fact that the diolefins in the feedstock were polymerized on the catalyst surface.

Recombinant mercaptans formed during the selective hydrodesulfurization of heavy FCC naphtha were stable and hard to be removed. The oxidation removal of these stable mercaptans with different catalysts and promoters was studied in the laboratory. The test results showed that an ion-pair-based catalyst combining with a complex-based promoter exhibited higher oxidation activity and stability than a conventional catalyst combining with a conventional promoter; with said catalyst combination the contents of mercaptan...

Recombinant mercaptans formed during the selective hydrodesulfurization of heavy FCC naphtha were stable and hard to be removed. The oxidation removal of these stable mercaptans with different catalysts and promoters was studied in the laboratory. The test results showed that an ion-pair-based catalyst combining with a complex-based promoter exhibited higher oxidation activity and stability than a conventional catalyst combining with a conventional promoter; with said catalyst combination the contents of mercaptan sulfurs in hydrotreated heavy FCC naphtha feeds (various from 19-34μg/g) could stably reduced to below 5μg/g during a 1 500h fixed-bed run. It was suggested that the catalytic oxidation of mercaptans could be used following the selective hydrodesulfurization of heavy FCC naphtha to produce low sulfur clean fuel.

采用选择性加氢技术对FCC汽油重馏分进行处理时,有可能产生微量的二次硫醇,其稳定性高,较难脱除。在实验室研究了该二次硫醇被催化氧化脱除的效果。结果表明,离子对型脱硫醇催化剂的脱硫醇活性明显优于常规单一金属钛菁催化剂,复配型活化剂的氧化脱硫醇活性明显优于常规单一型活化剂。以多种加氢催化裂化汽油重馏分为原料进行了1500h固定床催化氧化脱硫醇试验,结果表明,离子对型脱硫醇催化剂及复配型脱硫醇活化剂表现出良好的原料适应性及脱硫醇活性,脱后硫醇性硫含量可以稳定在5μg/g以下。该催化氧化脱硫醇工艺可以与加氢技术相配合,用于低硫清洁燃料的生产。
