【摘要】 以大庆石脑油为原料,研究了重整反应温度、压力及空速对重整效果的影响,优化得到了最佳工艺条件。研究了重整催化剂的金属功能和酸性功能对不同反应的影响规律;探讨了水氯平衡的原理,并推导了反应系统补水(氯)量的计算公式。结果表明,在一定工艺条件下,在已知反应物的物量及物性后,确定了反应区的合适水气氛(水分压)范围以后,就可计算出重整进料中水含量。经过蒸发塔后进料中水含量低于此值的差额量,就是应补的水量。而对一定的催化剂,当确定了最佳氯含量以后,就可以确定其对应的标准温度下的水氯分子比。然后校正到反应温度下的水氯分子比,就可以依据公式计算出重整进料中的氯含量。论文还对重整原料中掺炼催化汽油的可能性及效果进行了研究,实验研究和工业试生产表明,催化重整装置掺炼催化裂化汽油是可行的。根据重整原料和催化原料的性质差异,确定适当的掺炼比例,在实际的掺炼过程中,基于混合原料性质的劣质化,需要提高预加氢精制催化剂的性能及精制深度。更多还原

【Abstract】 Aiming at the present semi-regeneration catalytic reforming technology, the thesis investigated the effects of temperature, pressure and space velocity on the reforming reaction by experimental method and determined the optimum process conditions at last.The different effects of reforming catalyst of dual function on the reforming reaction were studied. The formula for calculating the mount of supplying chlorine to the reaction system was deducted and verified according to the water-chlorine balance principle. The results show that under certain technological conditions, the water content of the reforming feed stocks are calculated with knowing the amount and properties of the reaction products and determining the appropriate partial pressure of water. The supplement water amount is the difference between the water content of the feed going through the evaporating column and the above calculated value. To a certain catalyst, after determining the optimum chlorine content, the water-chlorine molecular ratios at the standard temperature and the reaction temperature can be confirmed. On the above basis, the chlorine content of the reforming feed can be calculated according to the above formula.The thesis also discussed the feasibility of mixing catalytic gasoline into the reforming feed. The results of experimental and industrial tests showed that it is necessary to fix the proper mixing proportion according to the different properties of reforming feed and catalyzing feed as the precondition of blending catalytic gasoline in the reforming feed in the refinery with rich pre-hydrogenation capability, i.e with deficient naphtha feed. And sometimes we should contact academes to perform the mixing experiments in question. During the practical blending process, the effects of the properties of mixed feed on the pre-hydrogenation catalyst need to be considered and the pre-hydrogenation catalyst can be changed according to the practical situation of the refinery.更多还原
