摘　　要：在中型试验装置上考察了循环氢中H_2S含量对催化裂化汽油加氢脱硫反应及烯烃加氢饱和反应的影响。结果表明,在催化裂化汽油选择性加氢脱硫过程中,循环氢中H_2S对加氢脱硫反应具有抑制作用、对烯烃加氢饱和反应具有促进作用,随着循环氢中H_2S含量的增加,催化剂的选择性下降。The effect of H2S content in recycle hydrogen on FCC naphtha hydrodesulfurization （HDS） was studied on a pilot plant. The results showed that H2S content in recycle hydrogen had significant effect on HDS reactions and olefin saturation：inhibition for the former and promotion for the latter. Thus,with the increase of H2 S content in recycle hydrogen,the selectivity of catalyst decreased.
