摘要： 国产RAX-2000A型对二甲苯吸附剂在中国石化齐鲁股份有限公司Parex装置上首次工业应用，装置运行半年进行了标定考核，在装置设计负荷的102.9%和111.4%原料流量下，分别取得了PX产品平均纯度99.77%、99.81%，平均理论收率99.05%、98.56%的运行结果，远远超过了技术合同预期值，工业试验取得成功。RAX-2000A开工至今两年有余，运行平稳，表现出良好的原料适应性和较低的床层压降，有望实现长周期运转。

Abstract: Commercial application trial of RAX-2000A adsorbent was carried out at Parex unit of Qilu petrochemical Corp. The calibration results were reported: p-xylene purity 99.77% and 99.81%，recovery 99.05% and 98.56% was achieved at 102.9% and 111.4% unit design charge rate. The unit was operated smoothly more than two years and long term operation is possible. Low bed pressure drop and adaptability of different feed were represent.
Key words: adsorbent, p-xylene, simulated moving bed, adsorption separation, commercial trial
