TLDR
In this paper, the effect of catalyst fouling on the stability and operation of adiabatic packed bed reactors was investigated for two poisoning mechanisms, and the effect was most predominant for packed beds in which nonunique pseudo steady states can exist.Abstract:
The effect of catalyst fouling on the stability and operation of adiabatic packed bed reactors was investigated for two poisoning mechanisms. The effect of fouling was found to be most predominant for packed beds in which nonunique pseudo steady states can exist. Fouling may cause the reactor to misbehave suddenly, with a violent temperature rise, after a long period of pacific operation.read more

Synthesis and performance of megaporous immobilized metal-ion affinity cryogels for recombinant protein capture and purification.
TL;DR: These immobilized metal-ion affinity cryogels show potential for a convenient single-step purification of recombinant proteins from raw cell extracts without the need for laborious pre-chromatographic sample clean-up procedures.

The Modeling of Catalyst Deactivation by Coke Formation
TL;DR: In this article, a fundamental kinetic framework is developed for deactivation by site coverage, coke growth and blockage in pores and networks of pores, and the effect of catalyst deactivation on the behavior of reactors is illustrated.

The effect of catalyst fouling on the performance of adiabatic packed-bed reactors — a theoretical study
Ezra K. T. Kam,Ronald Hughes +1 more
TL;DR: In this paper, a simple mathematical model has been developed for catalyst fouling in an adiabatic packed-bed reactor, where the main reaction was taken to be of Langmuir-Hinshelwood form, while first-order kinetics with respect to both the fouling precursor and the concentration of active sites were used for the rate.

The role of lattice oxygen in the dynamic behavior of oxide catalysts
TL;DR: In this paper, the authors investigated the effect of lattice oxygen storage property of an oxide catalyst on its dynamic response characteristics through an experimental study of 2-butene oxidation over vanadium oxide as a model reaction.
