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. 展开更多

The DDA-Ⅱ process aimed at manufacture of diesel fuel meeting the Euro-Ⅳ emission standard from inferior diesel feedstock has been developed and tested in pilot scale. This technology adopts non-noble metal catalysts and a highly integrated two-stage process scheme featuring low investment and operating cost and convenience in operation. Under an appropriate process regime the DDA-Ⅱ technology can process FCC LCO, a blend of straight-run diesel and FCC LCO, or the SR diesel to yield the diesel product streams meeting the Euro-Ⅳ or even higher emission standards. 展开更多
