Abstract
Processes are provided for the production of styrene monomer by oxidative dehydrogenation of EB using COas a soft oxidant. Carbon dioxide is used as the reaction diluent in one or more dehydrogenation reactors and to supply the heat required for the endothermic reaction of EB to styrene monomer. In the dehydrogenation reactors, two parallel reactions for styrene monomer formation occur simultaneously: (1) direct EB dehydrogenation to styrene monomer over a catalyst using heat provided by the carbon dioxide, and (2) oxidative dehydrogenation of EB with carbon dioxide to form styrene monomer.
