PROCESS FOR PRODUCING ALKENYL AROMATIC COMPOUND BY USING TEMPERATURE-RAISING TYPE REACTOR

摘要

PURPOSE: Provided is a process for producing an alkenyl compound and an alkenyl aromatic compound by dehydrogenating an alkyl compound or an alkyl aromatic compound in a temperature-raising type reactor, which can minimize the temperature drop of the reactant and the depression of pressure. CONSTITUTION: The process is performed in at least one radial dehydrogenating reactor having at least one vapor supply line(5) mounted through a catalyst layer(9), wherein a mixture of the alkyl compound and vapor is injected into the dehydrogenating reactor and the high temperature vapor is injected into the reactor through the vapor supply line(5) to flow the high temperature vapor in the opposite direction to the mixture of the alkyl compound and the vapor. The vapor supply line(5) has a diameter of 1-300mm and an inclination of 0-90 degree against the ground.
