The design of a dehydrogenation process for ethylbenzene using CO 2 as mild oxidant is put forward, including a technical and economical evaluation. Compared to the conventional process, this one has a more favorable equilibrium and can be operated at a lower temperature and lower energy consumption. The design is based on the data of the most promising catalyst investigated, i.e., Fe/Al/Zn. A single pass conversion of 26% with a selectivity to styrene of 91% for a CO 2/ethylbenzene ratio of 11:1 is observed. The process is designed according to the systematic process synthesis techniques. The low conversion and especially the high CO 2/ethylbenzene ratio leads to an unfeasible recycle flow. It reduces the CO 2/ethylbenzene ratio to 2:1. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA 2010 (Prague, Czech Republic 8/28/2010-9/1/2010).
