摘要： This invention relates to a process for the production of styrene monomer by the dehydrogenation or oxidative dehydrogenation of ethylbenzene in the presence of recycle gas and more particularly to a method of reducing the boiling point of liquid ethylbenzene feed in the production of styrene monomer. The process comprises the step of catalytically dehydrogenating or oxydehydrogenating ethylbenzene in the presence of a mixture, wherein the mixture substantially comprises carbon dioxide, thereby catalytically producing styrene monomer.

摘要： Processes are provided for the production of styrene monomer by oxidative dehydrogenation of EB using CO2 as 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.
