Abstract
A bimetallic-support interaction through Pt-Zn nanoparticles and uniform compact cylindrical ZSM-5 particles shows selectivity over 90% towards BTX and i-octane at controlled 60% conversion with negligible coke formation when reforming n-octane. This is a significant improvement compared to alternative Pt-Zn on conventional ZSM-5, with a selectivity of less than 40%.
摘要
双金属载体相互作用通过 Pt-Zn 纳米颗粒和均匀致密的圆柱形 ZSM-5 颗粒，在控制转化率为 60%的情况下，对 BTX 和异辛烷的选择性超过 90%，同时在重整正辛烷时几乎没有积碳生成。与传统 ZSM-5 上的替代 Pt-Zn 相比，这是一个显著的改进，其选择性小于 40%。
