1汽油吸附脱硫剂的研究与应用显示文摘日益严格的环保法规对生产低硫和超低硫清洁汽油技术提出了更高的要求。传统的加氢脱硫投资大,成本高。开发成本低、操作条件温和非加氢脱硫技术成为一种趋势。吸附脱硫技术具有操作简单、投资少、适合于深度脱硫和无污染等优点,工业应用前景广阔。综述了活性炭、改性分子筛、金属氧化物和改性黏土等多种吸附剂在制备、吸附机理、改性和脱硫效果等方面的研究和应用,对现有吸附脱硫剂存在的问题进行了讨论,展望了其应用前景。舒静 任丽丽 徐骞 2009工业催化2009,17,7:1
2Adsorptive desulfurization of diesel with mesoporous aluminosilicates显示文摘Mesoporous aluminosilicates (MAS) bearing microporous zeolite units and mesoporous structures were synthesized by the hydrothermal method. Adsorptive desulfurization ability of model oil and hy-drotreated diesel was studied. The effects of template concentration, crystalization time and calcination time were investigated. The desulfurization ability of adsorbents was improved by transitional metal ion-exchanging. The adsorptive desulfurization of diesel was carried out on a fixed-bed system. The results show that the adsorptive capacity is MAS>MCM-41>NaY. The improvement of desulfurization ability of MAS by Cu+ is more significant than that of Ag+.TANG Huang LI WangLiang LIU QingFen GUAN LiLi SONG JiaQing XING JianMin LIU HuiZhou 2009Science China Chemistry2009,52,3:0
