Özet
The current experimental work is on PROX kinetics over Pt-Sn/AC catalyst at 383 K in the presence of H2, CO2, H2O and CH4, mimicking WGS outlet of a fuel processor, which is used in production of PEMFC-grade H2from hydrocarbons. Parameters of the power-law kinetic model were estimated to be used in PROX reactor modeling and design calculations; reaction orders with respect to CO and O2were found as 0.47 and (− 0.57). The apparent activation energy of PROX over Pt-Sn/AC, was calculated as 45,300 J mol− 1in the temperature range of 383–403 K.
