The Thiele Modulus was developed to describe the relationship between diffusion and reaction rates in porous catalyst pellets with no mass transfer limitations. This value is generally used to measure the effectiveness factor of pellets. The Thiele modulus is represented by different symbols in different texts, but … See more The Thiele modulus was developed by Ernest Thiele in his paper 'Relation between catalytic activity and size of particle' in 1939. Thiele reasoned that a large enough particle has a reaction rate so rapid that diffusion forces … See more The derivation of the Thiele Modulus (from Hill) begins with a material balance on the catalyst pore. For a first-order irreversible reaction in a straight … See more Other order reactions may be solved in a similar manner as above. The results are listed below for irreversible reactions in straight cylindrical … See more Web4 Jul 2024 · The Thiele module is a dimensionless number. The value in the root term of Eq. represents the ratio of intrinsic reaction rate to diffusive mass transport in the porous structure. Since mass conservation has to be obeyed (Eq. 15), the same effectiveness factor has to be applied for all chemical species. Therefore, this simple model can only be ...
