What is Thiele Modulus?

The Thiele modulus is a dimensionless parameter used in the analysis of diffusion and reaction in porous catalyst particles. It provides a measure of the relative rates of diffusion and reaction within a catalyst particle and is particularly important in the study of heterogeneous catalysis.

What are Solid Catalyzed Reactions?

Solid-catalyzed reactions refer to chemical reactions where a solid material, known as a catalyst, facilitates the transformation of reactants into products without itself undergoing any significant change in composition. The use of solid catalysts is widespread in various industrial processes and research applications.
