摘要： 2019年对二甲苯（PX）吸附剂RAX-4000在中国石化海南炼油化工有限公司PX产能为1.0 Mt/a的PX吸附分离装置上首次工业应用。满负荷标定考核结果表明，PX产品质量分数平均值为99.81%，收率平均值为98.0%。装置开工5年，运行平稳，且已经过停工检修再开工的过程，其2024年1—9月的PX产品质量分数平均值为99.76%，收率平均值为98.0%。吸附塔压降随负荷有规律地变化，保持平稳，实现了装置的长周期稳定运转。

Abstract: The RAX-4000 para-xylene (PX) adsorbent has undergone its first industrial application in a 1.0 Mt/a PX adsorption separation unit at SINOPEC Hainan Petrochemical Co., Ltd. in 2019. The full-load calibration assessment results showed that the average purity of the PX product was 99.81% with the average yield of 98.0%. Since the unit start-up it has been running stably and has undergone shutdowns for maintenance and restarts during the five years. The average purity of the PX product was 99.76% with the average yield of 98.0% from January to September in 2024. The pressure drop in the adsorption tower varied regularly with the load and remained relatively stable, achieving long-term stable operation of the unit.
Key words: adsorbent, p-xylene, adsorptive separation, RAX-4000
