摘要:
Process for production of styrene by dehydrogenation of ethylbenzene in a reactor system comprising a dehydrogenation reactor and a fast riser catalyst regenerator.
摘要:
Integrated process for the production of alkyl and alkenyl substituted aromatic compounds which comprises simultaneously dehydrogentaing in a reactor-regenerator system a mixture containing an alkyl and an aromatic alkyl hydrocarbon coming from an alkylation unit and recycling the dehydrogenated alkyl hydrocarbon thus produced, after separation, to the alkylation unit.
摘要:
Reactor-regenerator device, comprising at least one reactor for catalytic dehydrogenation reactions of hydrocarbons and at least one regenerator of the catalyst of 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 co-current flow.
摘要:
Increase propane dehydrogenation activity of a partially deactivated dehydrogenation catalyst by heating the partially deactivated catalyst to a temperature of at least 660° C., conditioning the heated catalyst in an oxygen-containing atmosphere and, optionally, stripping molecular oxygen from the conditioned catalyst.
