Catalyst leaching from a solid support is very important issue that needs to be address before any catalytic process can be commercialised.In a previously submitted proposal, we have described a tandem flow reactor system to examine and quantify catalyst leaching in situ under continuous flow conditions. In this specific project will be aim to measure and quantify both catalyst leaching and deactivation, in an attempt to understand this important catalytic phenomenon. The work will involve continuous monitoring of catalyst performance over time (or two different time scales). Fundamental changes in the catalyst structure can be interrogated by Operando spectroscopy. This project will allow catalyst deactivation and leaching to be observed in situ under working conditions, to afford fundamental insights as well as process parameters that are important for scale-up of catalysis under continuous flow.Strategic Themes: Manufacturing the Future. Research Areas: Analytical Science, Physical Sciences, Catalysis

固体载体中的催化剂浸出是任何催化工艺商业化之前需要解决的非常重要的问题。在之前提交的提案中，我们描述了串联流反应器系统，用于在连续流动条件下原位检查和量化催化剂浸出。在这个具体项目中，目标是测量和量化催化剂的浸出和失活，以试图了解这一重要的催化现象。这项工作将涉及随着时间的推移（或两个不同的时间尺度）连续监测催化剂性能。催化剂结构的根本变化可以通过操作光谱来探究。该项目将允许在工作条件下原位观察催化剂失活和浸出，提供基本见解以及对于连续流动下催化放大非常重要的工艺参数。战略主题：制造未来。研究领域：分析科学、物理科学、催化
