ANALYSIS AND EXPERIMENTAL-STUDY OF THE TRANSFORMATION OF A NONISOTHERMAL SOLID GAS REACTING MEDIUM

This article concerns reacting solid-gas media, and the exploitation of their thermal properties in energy systems. Problems are encountered in the kinetics of these heterogeneous reactions and in the thermal phenomena characteristic of reacting porous media. A preliminary experimental study brought to light the existence of a coupling between these phenomena. By an appropriate choice of procedure, however, it was possible to separately identify the kinetic and thermal parameters occurring in the global transformation model, in a satisfactory way. This required detailed experimental data to decouple the two types of equation in the global model and to define the quadratic criteria to be minimised in each case. The experimental and kinetic studies are presented in this article. The thermal study is the subject of the second article. © 1991, Taylor & Francis Group, LLC. All rights reserved.
