Development and Commercial Application of High-Platinum CCR Catalyst with Low Coke Deposition Rate

借助于选择合适的添加剂并且优化催化剂作文和准备过程，没有减少它的特定的表面区域的为连续催化改过的高铂、低的焦炭免职催化剂 PS-VII (CCR ) 成功地被开发了。这催化剂 PS-VII 在一个 100-mL 飞行员测试单位被评估。学习结果证明在一样的反应条件下面，最新发达的催化剂 PS-VII 作为与存在相比在焦炭免职完成了 26% 减小高铂的 CCR 催化剂。在它在 1.39 Mt/a CCR 单位的第一个商业应用程序之上的这催化剂以它的特定的表面区域展出了好反摩擦性能和好稳定性。把这 PS-VII 类型催化剂比作原来的 CCR 催化剂当与低潜在的芳香的内容操作化工物品时，能在27.32%减少焦炭免职，与C_6^+液体产量，氢收益和 aromatics 产量的明显的增加一起，它能捉牢，这个问题在 CCR 能力扩大以后与催化剂新生限制联系了保证 CCR 的长周期的高负担的操作联合起来。

By means of selecting proper additives and optimizing catalyst composition and preparation procedures, a high-platinum and low coke deposition catalyst PS-Ⅶ for continuous catalytic reforming （CCR） without reducing its specific surface area has been successfully developed. This catalyst PS-Ⅶ was evaluated in a 100-mL pilot test unit. Study results showed that under the same reaction conditions the newly developed catalyst PS-Ⅶ achieved a 26% reduction in coke deposition as compared to the existing high-platinum CCR catalyst. This catalyst upon its first commercial application in a 1.39 Mt/a CCR unit had exhibited good anti-attrition performance and good stability in terms of its specific surface area. Compared to the original CCR catalyst this PS-Ⅶ type catalyst could reduce the coke deposition by 27.32% when operating on feedstock with low potential aromatic content, along with apparent increase in C6^＋ liquid yield, hydrogen yield and aromatics yield, which could grapple with the problem associated with the catalyst regeneration constraints after CCR capacity expansion to ensure the longcycle high-load operation of the CCR unit.
