On Inhibiting Runaway in Catalytic Reactors

Runaway Reactions in Batch Reactors

Case histories of 263 incidents involving runaway reactions of the type A + B→ products, carried out in industrial batch reactors have been analysed on the basis of unit processes involved, initiating factors and type of industry. The case histories were drawn from Health and Safety Executive files, industrial records and the open literature. Although the data has no absolute statistical value,...

Catalytic Reactors: A Review

Microstructured reactors for catalytic reactions

This review addresses the catalytic reactions performed in microstructured reactors, which are more and more recognized in recent years as a novel approach for chemistry and chemical process industry. They are particularly suited for highly exothermic and fast reactions allowing temperature control and isothermal operation. A brief evaluation of the advantages for gas-phase, liquid-phase, and g...

Feasibility of Pattern Formation in Catalytic Reactors

Abstract-The asymptotic stability regions for the patterned steady-state solution in a two-particle catalytic CSTR, established by Arce and Ramkrishna (1991, A.IC1I.E. J. 37,98-l lo), are constructed using two approaches, Liapunov’s direct method and the construction of a trapping region. In addition, the trapping regions are also constructed for uniform steady-state solutions. Stability region...

Investigation of spatially patterned catalytic reactors

The theme of this work is to enhance the performance of a primary reaction system by introducing dual-functionality into a packed-bed reactor via a spatial pattern. This paper focuses on a generic system in which the primary reaction is equilibrium-limited and an auxiliary reaction is incorporated to act as a drain-o! mechanism alleviating the equilibrium constraint. It is found that patterns i...
