Lugar: Basingstoke; Año: 2021 vol. 133 p. 17 - 17
This work presents a theoretical analysis for predicting the overall effectiveness factor (eta) for cylindrical geometries in a three-phase catalytic reaction system. Implicit expressions for eta, taking into account all the transport effects, gas-liquid mass transfer, liquid-solid mass transfer and intraparticle diffusion as well the chemical reaction were obtained. Various types of kinetics were considered; namely, Langmuir-Hinshelwood, power-law and zero-order. The obtained results are presented as a useful tool to be used in field of reactors design and laboratory kinetics data interpretation.
