Abstract
A process and apparatus comprise a reaction chamber that includes an aspect ratio between about 0.7 and 1.3 for establishing a dense catalyst bed in the reaction chamber while minimizing hot residence time of the product gas in a range that will not deteriorate product selectivity. We have found the dense catalyst bed is necessary to ensure sufficient contact between catalyst and feed gas.
