Kopplung von chemischen reaktionen und diffusions-prozessen bei nichtisothermen reaktionen

It was investigated, how a chemical reaction was affected by diffusion processes. The analytical solution of the problem is presented for three sample geometries (plate, cylinder, sphere). Furthermore we perform an analysis of the dimensions and get the result, that four dimensionless parameters are essential for the reaction rate. The influence of these parameters on the thermogravimetric curves is discussed and the results are compared with experimental findings.
