Novel crude styrene monomer production process by improved ethylbenzene feed method

摘要

The present invention is the improvement of the acetate in benzene to the reaction step of dehydrogenation to prepare a crude styrene monomer in the presence of a catalyst, by the input during the conventional constant-minute steam instead of the process condensate and steam in the ethylbenzene introduced mixture, ethylbenzene input method according relates to an energy-saving crude styrene monomer manufacturing process.
