Intrinsic kinetic study of 1-butene isomerization over magnesium oxide catalyst via a Berty stationary catalyst basket reactor

Abstract

The intrinsic kinetics of 1-butene isomerization over a commercial MgO catalyst was studied by using a Berty-type reactor (gradient-less recycle reactor) without limitations of heat-, external mass-, and internal mass-transfers.

Assessment of Concentration and Temperature Distribution in a Berty Reactor for an Exothermic Reaction

“…An attempt to overcome the drawbacks in PBRs for kinetic measurements is the application of continuously stirred tank reactors (CSTR). The advantage of an ideal CSTR is the absence of concentration and temperature gradients, which enables an analytical extraction of reaction rates at well-defined and uniform conditions. − There are two basic catalyst testing reactor designs that attempt to mimic the ideal CSTR: the Carberry reactor, where the catalyst is placed in a rotating basket, and the Berty reactor, where the catalyst is fixed and a turbine circulates the gas-phase internally. A combination of both designs, the Robinson-Mahoney reactor, uses a ring shaped catalyst basket and another possibility is the external circulation of the fluid by means of a gas or liquid pump .…”

“…Although ideally suited for kinetic measurements, Berty reactors are rather scarcely used for heterogeneously catalyzed reactions, as complete back-mixing of the gas phase is difficult to achieve. Yet, it is possible to derive high quality kinetic data from experiments within these reactors. ,− …”

“…Studies on the requirements for achieving high back-mixing in catalytic CSTRs have been performed experimentally ,,, and via Computational Fluid Dynamics (CFD) simulations. ,− Warna et al were the first to study a Berty reactor via CFD and found highly rotational flow. Later, the flow inside of a Robinson-Mahoney reactor and in a liquid–solid stirred tank reactor were studied.…”

Characterization of single-phase flow hydrodynamics in a Berty reactor using computational fluid dynamics (CFD)

“…Therefore, the Berty reactor has been studied for kinetic modeling with various chemical reactions. [3][4][5][6][7][8][9][10] According to Al-Ahmadi et al (1988), a Berty reactor was used to investigate the intrinsic kinetics of ethylene oxidation over an Ag/∝-Al 2 O 3 catalyst. 3 Their reactions were carried out in a temperature range of 240-320 °C and at a pressure of 21.42 atm.…”
