The Catalytic Pellet: A Rich Prototype for Engineering Up-Scaling
Arce, Pedro E.; Oyanader, Mario; Whitaker, Stephen
Chemical Engineering Education, v41 n3 p185-194 Sum 2007
This paper focuses on the use of scaling aspects for understanding transport processes with reaction in catalytic pores and pellets. The idea is to identify a systematic up-scaling approach in the learning process to help students with several concepts related to the transport-reaction process and the mathematical description associated with them. Items at the heart of this contribution are the integration of mathematical concepts with the physics of the system, the understanding of micro and macro scales, and the avoidance of approaches rooted in unit operation approaches, i.e., already scaled-up that are commonly used in traditional textbooks. In addition, the approach highlights the role of the catalytic pellet as an effective POK[38] in learning about multiple-scale systems. The proposed approach uses a microscopic formulation and an area-averaging process with a closure procedure to yield macro-transport equations. (Contains 4 figures and 6 footnotes.)
