摘要
分别以醋酸镍和硝酸镍为镍源,采用浸渍方法制备不同镍负载量的吸附脱硫催化剂,在小型固定流化床反应器对催化剂的脱硫性能进行评价,考察不同镍源及镍负载量对催化剂脱硫性能及辛烷值保留能力的影响。结果表明:在相同镍负载量的情况下,采用醋酸镍为镍源比采用硝酸镍为镍源制备的催化剂具有更大的比表面积和金属分散度、更高的初始脱硫活性和平衡活性及辛烷值保留能力。
A series of S Zorb catalysts with low nickel loading was prepared by impregnation method using nickel nitrate or nickel acetate as precursor, and the catalysts were evaluated in a small fixed fluid ized bed reactor to investigate the effect of the Ni loading and the source of nickel on the desulfurization performance and the octane number retention ability. The results show that under the condition of the same nickel loading, the catalysts prepared with nickel acetate have a larger specific surface area, better metal dispersion,higher initial and stable activity, and much lower octane number loss.
