“…No specific and separate studies have been carried out to directly quantify the aforementioned advantages with respect to the safety aspects of fluidized bed membrane reactors as was done by Coronas et al (1995) and Al-Sherehy et al (1998) for packed bed membrane reactors. However, Deshmukh et al (2005a,b,c) clearly demonstrated for the methanol partial oxidation to formaldehyde that operation at methanol inlet concentrations of 20% (twice that of industrial practice and with an overall inlet composition well inside the flammability limits) was possible, while still achieving virtually isothermal reactor operation.…”

Reaction kinetics of ethane partial oxidation to acetic acid

The partial oxidation of ethane to ethylene and acetic acid on supported MoVNbPd/TiO 2 (P25 of Degussa) has been investigated. Pd was added in a nano-metallic form. The catalyst composition was also different from similar studied catalysts. This results in a better selectivity towards acetic acid formation. The reaction was carried out in a tubular reactor at temperature range 225-275 °C, total pressure range 0-200 psig and oxygen percentage in the feed gas of 10-40%. The feed gas contains ethane and oxygen. In this work, we develop a kinetic model for the reaction for the developed catalyst. In this model, we assume that oxidation reactions take place on different sites; ethane oxidation takes place on one site, ethylene oxidation on another site, and CO is oxidized to CO 2 on a third site. The model exhibits good agreement with the experimental data.

“…A sizeable amount of information on this method is available in the literature especially for propane dehydrogenation [1][2][3][4]. A drawback is the potential problem of flammability, with the necessity of adopting a distributed feed in some instances [5].…”
