摘要：NOVELTY - This invention provides a reaction method for producing phenylethene by ethylbenzene dehydrogenation and hydroxidization. DETAILED DESCRIPTION - The dehydrogenation reactor applies radial reactor or axial radial reactor. Inside the bed fills dehydrogenation catalyst. The oxidative dehydrogenation reactor applies oxidative layer and absorbed layer double radial and dehydrogenation layer single radial compound bed form or absorbed layer, oxidative layer and dehydrogenation layer three radial compound bed form. The reaction material passes through sequentially the potassium adsorbed layer, oxidative catalyst layer anddehydrogenation catalyst layer in the oxidative dehydrogenation reactor. This invention has good potassium removing effect, low reactor pressure decrease, homogenous bed layer temperature distribution and simple reactor structure.
