摘要：
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. (C) 2012 Elsevier B.V.
