REACTOR-REGENERATOR DEVICE AND USE THEREOF IN THE PRODUCTION OF STYRENE

摘要

Reactor-regenerator device, comprising at least one reactor for catalytic dehydrogenation reactions of hydrocarbons and at least one regenerator of the catalyst o the "fast riser" type wherein the regenerator-riser is a substan­tially tubular apparatus for chemical reactions which com­prise a gaseous phase in close contact with a solid phase, wherein gas phase and solid particles move upwards in co­current flow.
