Pattern formation in fixed-bed catalytic reactors—II

Chemical Engineering Science, 1996
Abstract The possibility of spatial patterns in packed-bed catalytic reactors to improve reactor operation is addressed in this paper with respect to several fundamental issues. The analysis is accomplished with an early model of Liu and Amundson (1962, Ind. Engng Chem. Fundam.

Heat transfer in fixed-bed reactors

The Chemical Engineering Journal, 1973
Abstract For optimum design of fixed-bed reactors the temperature must be predictable at every point. The effects of temperature distribution upon reactor perfo In the design of non-adiabatic reactors, it is particularly important to use accurate values of the wall heat transfer coefficient and the effective th Available correlations for the key ...

Waste Tire Pyrolysis: Comparison between Fixed Bed Reactor and Moving Bed Reactor

Industrial & Engineering Chemistry Research, 2008
Waste tire pyrolysis has been performed in a fixed bed and a moving bed reactor, in order to know the influence of the reactor type on the yields and product characteristics. Typical pyrolysis conditions have been used in both reactors (600 °C and inert atmosphere). The moving bed reactor operates in continuous mode, and it is designed to process up to

Fixed-Bed Reactors with Regenerative Cooling

Industrial & Engineering Chemistry Fundamentals, 1971
A regeneratively cooled fixed-bed reactor system was studied theoretically. It consists of two sections which alternate roles as reactor and heat regenerator by periodic flow reversals. Calculations were performed for a single exothermic reaction using a forward cell model.

Dynamic Behaviour of Fixed Bed Catalytic Reactors

IFAC Proceedings Volumes, 1989
Abstract Characterizing dynamic behaviour depends on identifying all the significant factors which must be included in models which are used to describe the system. As operation at higher performance is demanded the level of approximation assumes greater importance.

Mathematical models of fixed bed reactors

Berichte der Bunsengesellschaft für physikalische Chemie, 1970
AbstractThis paper discusses in a semi‐qualitative way mathematical models for fixed bed chemical reactors in which a single chemical reaction takes place. Various models are discussed with some mention of the difficulties of computation, stability, and the anatomy and pathology of systems in which chemical reaction is coupled with heat and mass ...

FIXED BED REACTOR DYNAMICS AND CONTROL – A REVIEW

IFAC Proceedings Volumes, 1986
Abstract The industrial diversity of fixed bed reactors offers a challenging and relevant set of control problems. These intricate problems arise due to the rather complex dynamics of fixed bed reactors and to the complexity of actual reactor configurations. Many of these control problems are nonlinear and multi-variable. During the last decade fixed
