OSTI ID:5677647
This patent describes a process for the aromatization of an aliphatic feedstream. It comprises fluidizing finely divided solid particles in a combustion zone; charging oxygen-containing combustion gas and fuel to the combustion zone under combustion conditions; withdrawing a stream of finely divided particles from the combustion zone; flowing the withdrawn stream of finely divided particles above to a cracking/dehydrogenation zone; fluidizing the finely divided particles above in an aliphatic feedstream under conditions within the cracking/dehydrogenation zone controlled to at least partially crack and at least partially dehydrogenate the aliphatic feedstream to form an intermediate product stream containing a quantity of C{sub 4}-olefins such that the exothermic catalytic conversion of the C{sub 4}-olefins is sufficient to supply a portion of the endothermic heat of reaction for the endothermic catalytic conversion of paraffins contained in the intermediate feedstream to aromatics; contacting the intermediate product stream with an aromatization catalyst under aromatization conditions sufficient to evolve an aromatics-rich products stream.
