摘要
本工作介绍了国产GS-DS催化剂在85 kt/a苯乙烯装置上的应用情况,并通过装置标定和长周期运行数据分析,对催化剂性能进行评价。结果表明:在乙苯进料负荷为110.5%、水蒸气和乙苯质量比(水蒸气/乙苯比)为1.33、反应压力为37.0 kPa的条件下,乙苯转化率为62.4%,苯乙烯选择性高达97.3%,催化剂使用寿命可长达45个月。该催化剂表现出良好的稳定性,其抗波动能力、抗结焦能力和抗粉碎能力都较高,应用前景广阔。
This paper introduces the application of the domestic GS-DS catalyst in an 85 kt/a styrene unit and evaluates the catalyst performance through industrial plant calibration and long-term operation data analysis.The results indicated that under the conditions of an ethylbenzene feed load of 110.5%,steam/ethylbenzene ratio(mass ratio)of 1.33,and a reaction pressure of 37.0 kPa,the ethylbenzene conversion rate reached 62.4%,the styrene selectivity was as high as 97.3%,and the catalyst service life was up to 45 months.The catalyst exhibited good stability,with strong capabilities in anti-fluctuation,anti-coking,and anti-crushing,showing broad application prospects.
