โœฆ Synopsis


We examine the overall behavior of a mixture in which nonuniformly coupled bimolecular reactions proceed at comparable rates. Using a regular perturbation method, we derive approximate equations governing the behavior of the reactant lump in a plug-flow or batch reactor. We show that overall second-order kinetics appear as the leading order and that higher-order terms can easily be constructed. With no more than three terms the perturbation series shows excellent agreement with the exact result. The result gives a simple expression for correlating experimental data. We also discuss how more complex systems can be treated by the present perturbative scheme.

This paper addresses the overall behavior of a reaction mixture in which many irreversible bimolecular reactions occur in catalyst particles of three different shapes (slab, long cylinder, and sphere). Specifically, we develop a priori upper and lower bounds on the effectiveness factor for the mixtu

Abslraet-In many chemical processes, particularly those related to the petroleum industry, the number of reacting species is very large. It is often expedient to lump all the species into a few classes for practical purposes. This paper presents a theoretical study on the exact lumping of a mono-or/
