Abstract

Intrinsic reaction kinetics is an essential information in catalytic reaction engineering. This paper reviews the two laboratory reactors, i.e., the packed-bed reactor and gradient-less recycle reactor commonly employed for determining the intrinsic reaction kinetics of heterogeneous catalysts. Although both reactors have been well-known for kinetic studies for a long time, there are still efforts to address some essential issues and to further develop the reactors. For example, a new design of the gradient-less recycle reactor was developed to broaden the operating window for intrinsic kinetic studies at low pressure. Furthermore, the intrinsic kinetic modeling in the gradient-less recycle reactor and packed-bed reactor, including the effects of mass transfer and axial dispersion, was also investigated. This review article provides in detail the types of both reactors, the development of both packed-bed reactor and gradient-less recycle reactor, intrinsic kinetic modeling, and the methods for determining heat- and mass- transfer limitations. All of these point out the suitable methods for determining intrinsic kinetics and perspectives for future works.
