摘　　要：针对二甲苯异构化催化剂的需求热点,开发了新型C8芳烃异构化催化剂。该催化剂在抚顺石化公司催化剂厂工业批量生产36 t,在辽阳分公司对二甲苯装置上进行工业应用,并针对该催化剂的反应特点,对装置进行改造,催化剂投料后,乙苯转化率达到22.88%,PX/ΣX达到23.32。从工业标定的结果和装置运行情况看,各项技术指标均达到或超过了项目合同指标要求。New C8 aromatic isomerization catalysts were developed to meet increasing demand of xylene isomerization catalysts. Fushun petrochemical company catalyst plant produced 36 tons of isomerization catalyst;the catalyst was applied in Liaoyang petrochemical company xylene isomerization unit which had been reconstructed based on catalyst reaction performance. After loading the catalyst, ethylbenzene conversion reached to 22.88%and PX/ΣX was up to 23.32. The unit calibration results showed that the running index could reach the target of contract.
