Title : Heterogeneous catalysis: Reaction mechanism and kinetic models
Abstract:
Majority of the processes in chemical industries requires the use of catalyst which indirectly contributes to the world GDP. Most of the catalytic processes are heterogeneous in nature which forms the foundation of modern Chemical Engineering. Heterogeneous catalysis plays an important role in several industrial processes where chemical reactions occur at the interface between two phases which typically involves a solid catalyst and reactant molecules which may in the gas or liquid form. The reaction mechanism of heterogeneous catalysis is really fascinating as it takes places in wide range of stages. It creates a cycle where used catalyst is being regenerated, regaining its strength for the next reaction. The elementary steps in the heterogeneous catalysis contributes to the overall rate of reaction thus influencing the catalysts activity and selectivity. Kinetic models play a crucial role in formulating it. Traditional and Modern kinetic models are discovered with the advancements in computational methods thus offering insights into catalyst performance and optimizing the industrial processes. These models help in accurate prediction of rate constants, reaction intermediates and activation energies facilitating the design of more efficient catalysts. Understanding of the fundamental mechanisms and kinetics of heterogeneous catalysis is therefore very important for bringing up advancements in sustainable energy and chemical production processes. This study highlights the significance of integrating reaction mechanisms and kinetic modelling to stimulate innovations in catalytic technologies for industrial applications.
