Pore and solid diffusion models for fixed-bed adsorbers

Thomas W. Weber, +1 more
- 01 Mar 1974 - 
TL;DR: In this article, the prosity factor of the pore model is shown to be very important, especially as the porosity decreases, and the importance of the two diffusional models with respect to the predicted breakthrough curves is demonstrated.

Continuous flow systems

P.V. Danckwerts
- 01 Feb 1953 - 
TL;DR: In this article, the authors proposed a method to predict the distribution of residence-times in large systems using distribution-functions for residence times, which can be used to calculate the efficiencies of reactors and blenders.

Multiple‐Rate Mass Transfer for Modeling Diffusion and Surface Reactions in Media with Pore‐Scale Heterogeneity

Roy Haggerty, +1 more
- 01 Oct 1995 - 
TL;DR: In this paper, a multirate model is proposed to model small-scale variation in rates and types of mass transfer by using a series of first-order equations to represent each of the mass transfer processes.
