Abstract
An endothermic catalytic dehydrogenation process conducted in gas phase in system including a reactor with a catalyst bed including an inorganic catalytic material and a first inert material including the steps of: feeding a first stream having an alkane of the formulae I CnH2n+1R1 with n≧3 and R1═H or aryl to be dehydrogenated into the reactor, and simultaneously or subsequently feeding a second stream including a mixture of an inert gas and a reactive gas selected from the group of alkanes of the formulae II CmH2m+2 with m≧2, or alkenes of the formulae III CmH2m with m≧2. The alkane to be dehydrogenated of formulae I in first stream has at least one more carbon atom than the alkane of formulae II and alkene of formulae III in the second stream.
Claims20
An endothermic catalytic dehydrogenation process conducted in gas phase in at least one reactor system comprising at least one reactor with at least one catalyst bed comprising at least one inorganic catalytic material and at least one first inert material comprising the steps of:
- feeding at least one first stream comprising at least one alkane to be dehydrogenated of the general formulae I CnH2n+1R1 with n≧3 and R1═H or aryl into the at least one reactor, and
- simultaneously or subsequently feeding at least one second stream comprising a mixture of at least one inert gas and at least one reactive gas selected from the group of alkanes of the general formulae II CmH2m+2 with m≧2, or alkenes of the general formulae III CmH2m with m≧2,
- wherein the alkane to be dehydrogenated of the general formulae I in the at least one first stream comprises at least one more carbon atom than the alkane of the general formulae II and alkene of the general formulae III in the at least one second stream.
