摘　　要：对某公司100×10^(4) t/a催化汽油加氢装置的3台反应器器外再生催化剂进行标定,对装置的标定结果进行了分析。结果表明,预加氢反应器、加氢脱硫反应器、加氢后处理反应器内气液相分配均匀,再生后的PHG-131、PHG-111、PHG-151催化剂脱硫效果良好,满足国Ⅵ标准中硫含量要求,各反应器催化剂床层入口温度降低且烯烃饱和少,辛烷值损失小。It calibrated three external regenerated catalysts of a 100×10^(4) t/a catalytic gasoline hydrogenation unit of a company and analyzedthe calibration results.The results showed that the gas and liquid phase were evenly distributed in the pre-hydrogenation reactor,hydrodesulfurization reactor and hydrogenation reprocessing reactor,the desulfurization effect of the regenerated PHG-131,PHG-111 and PHG-151 catalysts was good,which met the requirements of the nationalⅥstandard for sulfur content.The inlet temperature of the catalyst bed in each reactor was reduced,the olefin saturation was less,and the octane loss was small.
