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
