Device for carrying out catalyzed reactions

摘要

The catalytic process for producing maleic anhydride employs a catalytic device formed of pairs of vertically extending vapor permeable walls which define flow channels between the pairs of walls. In addition, each pair of walls defines an interspace which contains a catalyst. A mixture of air and n-butane is passed through the flow channels while a heat exchange medium, such as a molten salt, is passed in heat exchange relation to the catalytic device while effecting an exothermic catalytic reaction of the mixture within the catalytic device. The resulting gaseous maleic anhydride is produced as a product.
