Title
Microkinetic modeling of the hydrogenation of nitrate in water on Pd–Sn/Al2O3 catalyst
Abstract

An alumina supported palladium–tin catalyst was investigated in the nitrate catalytic hydrogenation in water and was active and selective for the reaction. A reaction mechanism was proposed using a microkinetic model without assuming the rate-determining step of the process. Kinetics measurements were performed in a semi-batch reactor varying the temperature in a range 278–318 K. A statistical fit was achieved with concentration data, obtained from the microkinetic modeling and the experimental practice, providing satisfactory statistical variance.
