Abstract
Standard catalytic dehydrogenation of alkanes to form olefins has a number of undesirable features as a commercial process. For example, the usual dehydrogenation catalyst such as Cr//2O//3/Al//2O//3 rapidly cokes and deactivates under typical operating conditions. This catalyst may be regenerated with air in a fixed bed or recirculating bed, but the related equipment necessary for this requires an undesirably large capital investment for a commercial plant. Oxidative dehydrogenation is an obvious possibility, but it is difficult to achieve high catalytic selectivity from paraffins to desired products when air or oxygen is used. As an alternative to these processes, carbon dioxide was investigated as an exhaust to effect dehydrogenation and coke removal.
