Abstract

The gas phase oxidation of butane was studied in a fixed bed to obtain an improved kinetic model to support Du Font's recirculating solids reactor technology. The experiments were done in an integral reactor, containing 0.5 g of unsupported V/P/O catalyst. Feed composition, temperature, and space time were varied independently over a wide range. Six sets of rate expressions were considered based upon a parallel/consecutive reaction network. Best results were obtained with a modified Sharma model and an adsorption model. Both models describe adequately the experimentally found inhibition by water and maleic anhydride. Selectivity loss to CO and CO2 occurs primarily via the parallel reaction, though at very high butane conversion the loss resulting from maleic anhydride degradation also becomes important.
