Abstract:
A catalyst is a substance which increases the rate at which a chemical reaction approaches equilibrium without becoming itself permanently involved,
Types of Catalysis (homogeneously catalyzed and Heterogeneous catalysis), Industrial Importance of Catalysis: Catalysts are the workhorses of chemical transformations in the industry. Classification of Catalysts :(
Unsupported (Bulk) Catalysts,
Supported Catalysts).General Methods of Preparation for Supported Catalyst Systems: (Impregnation, Adsorption from Solution, Chemical Vapour Deposition (CVD), Co-precipitation, Deposition, Regenerability).
Catalyst design parameters: (Activity, Stability, Selectivity). Catalyst deactivation: deactivation leads to a shortened catalyst lifetime, and the replacement of an aged catalyst to a new one is determined by the industrial processes for which the catalyst is used.
