Linking diffusion and reaction - Understanding and controlling transport processes to optimize rates and selectivities for (micro-)porous catalysts

该项目的目标是测量、分析和模拟二甲苯气相异构化的反应物、中间体和产物的竞争传输，目的是为设计结合高活性和高对位选择性的新一代催化剂提供概念。这将包括在活性和非活性条件下的传输测量，以研究活性中心的复盖度对催化性能的影响。基于铝边X射线吸收光谱和反应条件下的MAS-核磁共振光谱的新的实验方法将与压力和浓度阶跃实验相结合，跟踪明确定义和条件下的传输和反应活性，以探索通过控制反应条件下孔内的传输特性来提高活性和选择性的概念。

The objective of the project is to measure, analyze, and model the competitive transport of reactants, intermediates, and products for the gas phase isomerization of xylenes with the aim of developing concepts for the design of a new generation of catalysts, which combine high activity with high para selectivity. This will include transport measurement under reactive and non-reactive conditions to study the role of the coverage of the active sites on the catalytic properties. Novel experimental approaches based on X-Ray absorption spectroscopy on the Al edge and MAS-NMR spectroscopy under reaction conditions will be combined with pressure and concentration step experiments to follow transport and reactivity under well-defined and conditions to explore concepts for enhancing the activity and selectivity by controlling the transport properties inside the pores under reaction conditions.
