Abstract: In order to obtain the process design data of platforming plant, the pilot plant studies have been made in a multiple adiabatic reactor system containing three or four reactors in series. The pilot unit has a charge capacity oF200-350 kilograms of naphtha per day. The charge stock was 85-125℃ cut of straight run Yumen gasolines for toluene production. A heat balance method based on compositions of charge stoch and platforming products was developed to evaluate the temperature drop in each reactor. The results indicated that each reactor reached adiabatic conditions. The three reactor system operation gave 25% toluene yield (weight basis on feed), corresponding to 82% of the maximum possible from conversion of naphthenes in the charge. Li.quid yield of the platformate was 92% (weight basis). Byproduct hydrogen had a purity of 95% by volume.

摘要： 为了提供铂重整工业装置的设计数据及操作指标,进行了三个和四个串联绝热反应器的中型试验。铂重整中型装置的处理量为每日200—350公斤。原料油为玉门直馏汽油中85—125℃七碳烃馏份,以生产甲苯为主。采用三个反应器时,合理的操作条件为进口温度,490℃;压力,30气压;汽油分子循环比,6-7∶1;空速,3.稳定重整油的液收率为92％（重量）,甲苯产率为25％（重量）,副产品氢气纯度为95％,氢气产率为1.8％（重量,对原料油）。每个反应器催化剂容量的比例为1∶1∶1。采用四个反应器时,在同样的操作条件下,液收率为86％（重量）。甲苯产率为28％（重量）。由于第四反应器的平均床层温度过高,催化剂积炭较快,催化剂的活性不能持久。但如将第四反应器进口温度降至470℃,第四反应器即会失去效用。因此不宜采用四个反应器。在试验过程中,用热平衡方法证明中型反应器能达到绝热的条件,因此保证了工业装置设计数据的代表性。试验时,并测定了各反应器的温度降。反应系统内反应物和生成物的总热容量,以及各反应器内生成芳香烃的反应热是按照热力学基本数据计算而得的。
