Multiplicities and instabilities in chemically reacting systems — a review
Luis F. Razon,Roger A. Schmitz +1 more
TL;DR: In this paper, a review brings attention to much of the recent literature describing these developments and their applications, particularly regarding complex and chaotic oscillations, as well as reported experimental observations which, in many cases, have provided support for prior theory and in many others, have led to new theoretical developments.
Homogenization in chemical reactive flows
TL;DR: In this paper, the homogenization of two nonlinear models for chemical reactive flows through the exterior of a domain containing peri- odically distributed reactive solid grains (or reactive obstacles).

Singular Langmuir–Hinshelwood Reaction-Diffusion Problems: Strong Adsorption Under Quasi-Isothermal Conditions
José M. Vega,A. Liñán +1 more
TL;DR: In this article, the steady state reaction-diffusion problem for a permeable catalytic particle with Langmuir-Hinshelwood kinetics under isothermal and quasi-isothermal conditions was considered.

Characterizing the strange term in critical size homogenization: Quasilinear equations with a general microscopic boundary condition
TL;DR: In this paper, the authors considered the problem of boundary value problems in n-dimensional domains with periodically placed particles, with a general microscopic boundary condition on the particles and a p-Laplace diffusion operator on the interior, in the case of critical size.

Study on the possible existence of multiplicity features in ethene hydrogenation over platinum/boehmite catalysts
TL;DR: In this paper, the authors examined the possible existence of multiplicity features in ethene hydrogenation over a very short fixed bed of platinum/boehmite catalysts and concluded that the multiplicity cannot be attributed to a purely kinetic process, but it results from the interaction of the chemical reaction and the heat transfer process.
