Parallel Reaction System for Ethylbenzene Dehydrogenation

摘要

In a first step, contacting hydrocarbons and vapors with a dehydrogenation reaction catalyst under dehydrogenation conditions to obtain a first stage effluent, heating the first stage effluent, and dehydrogenation in a second stage Contacting the heated first stage effluent under conditions with a dehydrogenation catalyst to obtain a second stage effluent comprising the dehydrogenation reaction product, wherein the first stage is disposed in parallel And a second reactor, wherein the second step comprises a third reactor connected in series with the first reactor and the second reactor. Also provided is a multistage dehydrogenation reaction system for carrying out the dehydrogenation reaction.
