The proposed PhD is a collaboration between Imperial College London and Johnson Matthey, UK aiming to broaden the literature on the powder flow behaviour of zeolites by establishing a link between the physical/chemical properties of zeolites and the flow behaviour in different processes. Particular attention will be given to the influence of thermal processes, such as calcination and drying on the powder flow. The experiments will be conducted for FMI framework zeolites from which the ZSM-5 type will be extensively studied.The end goal is to build a mechanistic understanding of how single-particle properties of zeolites relate to the bulk behaviour which can immensely help the development of approaches for efficient and profitable powder processing and manufacture. Hence, this work will prove greatly beneficial for the prediction of technical risks and potential issues in powder flow during scale-up, the minimisation of modelling time which requires powder flow estimation via measurements, the successful design of equipment and tuning the properties of the zeolite and the understanding of the impact of each process on the quality of the zeolite. Most importantly, relating the physiochemical properties of the zeolite to its powder flow behaviour will ultimately pave the way for establishing a link between the powder flow characteristics of each process.

拟议的博士学位是帝国理工学院伦敦和约翰逊万丰，英国之间的合作，旨在扩大沸石的粉末流动行为的文献，通过建立沸石的物理/化学性质和不同工艺中的流动行为之间的联系。将特别注意热过程的影响，如煅烧和干燥粉末流动。这些实验将针对FMI骨架沸石进行，从中将广泛研究ZSM-5类型。最终目标是从机理上了解沸石的单颗粒性质与整体行为之间的关系，这将极大地有助于开发高效和有利可图的粉末加工和制造方法。因此，这项工作将被证明是非常有益的技术风险和潜在问题的预测，在放大过程中的粉末流，最小化的建模时间，需要通过测量，设备的成功设计和调整的性能的沸石和沸石的质量上的每个过程的影响的理解的粉末流估计。最重要的是，将沸石的物理化学性质与其粉末流动行为联系起来，最终将为建立每种工艺的粉末流动特性之间的联系铺平道路。
