Heterogeneous Catalysis and Catalytic Processes

Heterogeneous Catalysis and Catalytic Processes. Instructor: Prof. K. K. Pant, Department of Chemical Engineering, IIT Delhi. More than 907f all the chemical product formation processes are catalytic in nature and heterogeneous catalysis plays an enormous role. Improving the catalyst effectiveness is the best way to ensure cleaner and efficient industrial processes. This course examines the detailed structures, preparation methods and reactivity of various solid catalysts like zeolites, supported metals and metal-support interactions, carbon catalysts, monoliths and others. The relationship between the structures and reactivity of important catalysts used in hydrocarbon conversion and treating processes will be examined to rationalize how they accomplish specific catalytic transformations. The characterization process to understand the textural and chemical properties of the metal /support will be discussed along with reaction mechanism on a solid surface. (from nptel.ac.in)
