【摘要】 RAX-4000是由中石化石油化工科学研究院有限公司开发的新一代对二甲苯吸附剂，其吸附容量、吸附选择性及原料处理能力较上一代吸附剂有显著提高。RAX-4000吸附剂于2020年1月在中国石化金陵分公司芳烃联合装置吸附分离单元成功应用，长周期工业应用结果表明：对二甲苯纯度(w)为99.84%,单程收率为99.0%,运行剂油质量比为1.05,吸附塔平均压降为0.21 MPa。开工近3年来RAX-4000吸附剂运行平稳，技术指标先进。更多还原

【Abstract】 RAX-4000 is a new generation of p-xylene adsorbent developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd. Its adsorption capacity, adsorption selectivity and productivity are significantly improved compared with the previous generation of adsorbent. RAX-4000 was successfully applied in the adsorptive separation unit of aromatics complex in SINOPEC Jinling Company. The results of long-period industrial application showed that the purity of p-xylene was 99.84%,the single-pass yield was 99.0%,the desorbent-to-feed mass ratio was 1.05,and the average chamber pressure drop was 0.21 MPa. RAX-4000 has been running smoothly and its technical index was advanced in the past 3 years.更多还原
