Abstract
A process for the dehydrogenation of an alcoholic aromatic hydrocarbon in the presence of water vapor, comprising passing a mixture of said hydrocarbon and water vapor through a plurality of serial catalytic dehydrogenation reaction zones, in which the outgoing fluid of a reaction zone is introduced into the next reaction zone and wherein the temperature of said mixture of hydrocarbon and water vapor ranges from about 580ºC to about 650º c, characterized by the improvement comprising reheating the outgoing fluid from each reaction zone by indirect heat exchange with steam in a heat exchanger constructed of stainless steel with high nickel content, and using said steam from said heat exchange stage to mix it with said hydrocarbon feed.
