On the Method of Calculating Effectiveness Factor of the Porous Catalyst in Any Reaction

01 Jan 1956-Chemical Engineering-Vol. 20, Iss: 1, pp 11-14
TL;DR: In this article, the effectiveness factor of the porous catalyst, which depends upon the diffusibility of reactants or products insid catalyst as well as on the pure chemical reaction, had been developed to the first order reaction or to a few other cases.
Abstract: The method of Calculating effectiveness factor of the porous catalyst, which factor depends upon the diffusibility of reactants or products insid catalyst as well as on the pure chemical reaction, had formerly been developed to the first order reaction or to a few other cases. Whereupon the authors have tried and succeeded in extending its application to the cases in general in which chemical reaction rates are given and equations are presented as a function of constitution. As an example, the calculation method for ammonia synthesis is illustrated.

TL;DR: In this paper, the effect of intraparticle temperature distribution on the catalytic effectiveness factor was derived and its magnitude was estimated using an approximate solution, and it was shown that for the several cases examined the term containing effect of temperature is less than 10% of that due to the concentration effect.
