Oxidation kinetics of propane-air mixture over NiCo2O4 catalyst emitted from LPG vehicles

Abstract

This paper describes the kinetics of catalytic air oxidation of propane. The kinetics data were collected in a plug flow tubular reactor. The experiments were performed over the NiCo2O4 catalyst prepared by co-precipitation method followed by calcination at 400 °C. The kinetic data were collected under the fol-lowing conditions: 200 mg of catalyst, 2.5 % of propane in air, total flow rate of 60 mL/min, and tem-perature ranges of 130-170 °C. The data were fitted to the power law rate equation. The activation energy and frequency factor were found to be 59.3 kJ/g mol and 2.9×108 (mol)0.47.L0.53/g cat.h, respectively.
