RESEARCH AREAS

My research works are focused on utilization of low value by-products, waste materials or renewable feedstocks to produce value-added products/ or energy or develop environmentally benign process. Catalyst preparation or modification and its characterization and applications in various upcoming fields are the heart of my works. At present, the development of process and catalyst for production of hydrogen from renewable feedstocks is the theme of my research. The followings are some of my key research areas.

· Chemical Reaction Engineering

· Catalysis  and Kinetics

· Petroleum Refinery Engineering

· Petrochemicals

· Fluid Phase Equilibrium

· Modeling and Simulation
