Description:
Deep (complete) catalytic combustion (oxidation) of volatile organic compounds (VOCs) is emerging as an important emission control technique. A fundamental study was carried out for low-temperature deep oxidation of n-hexane and benzene over a 0.1% Pt, 3% Ni/gamma-Al2O3 catalyst. These VOCs were subjected to oxidation as single components and as a binary mixture at temperatures ranging from 160 to 360 degrees C, n-Hexane oxidation was significantly inhibited in the mixtures. An approach based on the Mars-Van Krevelen rate model was used to explain the results. Kinetic parameters were developed for the individual VOCs based on single component differential reactor data. These kinetic parameters were then incorporated into a proposed multicomponent Mars-Van Krevelen rate model to predict the experimental conversions in the binary mixture. The model was found to be reasonably successful in predicting the conversion of benzene and n-hexane in their binary mixture. (Copyright (c) Elsevier Science Publishers B.V. 1988.)
