Experimental and theoretical research of thermochemical processes

Thermochemical processes involve phenomena that occur at different scales. For example, chemical reactions take place on a microscale in which reactant molecules interact to form products. It is from this scale that information regarding intrinsic chemical kinetics and thermodynamic parameters can be obtained. Another scale is the mesoscale or Fick’s scale, in which the phenomena of matter, energy and momentum transport are important, which can take place in the free medium or in porous media. T he knowledge of these phenomena is fundamental to be able to know the so-called global reaction kinetics and details of the porous structure of the solids that are com monly involved in this type of reaction.
