Agglomeration behavior of FCC - Catalyst-particles in spray drying

Publikation: Beitrag in FachzeitschriftKonferenzartikelBeigetragen



Composition of certain crude oils and their availability represent challenges for the oil and the chemical industry. Feedstocks, such as shale oil, have higher amounts of metals and heavy components, which cause difficulties for the oil refining and reduce the yield of valuable products in classic refining schemes. Furthermore, increasing energy consumption and the limitation of alternative energy resources encourage studies for modification and optimization of current oil refining processes. One of these processes is the Fluid Catalytic Cracking (FCC), where distillation gasoil molecules are cracked to produce gasoline and olefins. This can be achieved using zeolite as an active part of a multicomponent catalyst. One strategy for the shaping of this multicomponent catalyst is the spray drying, where the catalyst components are agglomerated together for the formulation of a new granulate. The agglomeration behavior of this component particles has not been studied in detail, especially referred to the binders and their interaction with the other catalyst components. Aim of this work is the study of the agglomeration influence of the binder and the drying conditions in the shaping process. The suspensions were prepared with different binders and dried in different operational conditions. The obtained results indicate that particle agglomeration depends on the dispersion grade of the solid particles in the suspension, the size of the particles in that medium, and the type of binder.
