论述了100t ROC-Z1催化剂在镇海炼化重整装置上取代工业白土的工业试验过程。工业试验结果表明：相对于普通白土颗粒，催化剂 ROC-Z1脱烯烃效果优异，使用寿命长，单操作周期内产品质量达标时长为普通白土的3.5倍，反应前后重整油组分中苯、甲苯、C8芳烃、C9芳烃以及非芳烃组分均无明显变化。ROC-Z1催化剂替代白土脱除PX生产原料中烯烃的新技术不但可以促进PX装置本身的清洁生产，而且将有力地减少白土的消耗，减轻对矿产资源的依赖，大幅度地减少废弃物的处置量。在催化剂脱除芳烃中烯烃的机理研究过程中，通过采用色谱-质谱联用的方法，分析了催化剂处理前后原料的变化，研究证实了ROC-Z1催化剂脱除芳烃中烯烃的反应为烷基化反应，遵循正碳离子机理。

Mechanism of olefins removal on catalyst ROC-Z1 was studied in this paper. Experiments showed that the reaction belonged to alkylation,followed by carbocation process. The industrial test of ROC-Z1 was carried out in reforming device at Sinopec Zhenhai refining and Chemical Company at the scale of 100 tons. The results of the industrial test showed that the lifetime of ROC-Z1 was 3.5 times of that of commercial clay,and no significant change was observed on the quantity or distribution of the aromatic hydrocarbons. Catalyst ROC-Z1 is a cost-effective catalyst for the removal of trace olefins from aromatics.
