HYDROCARBON DEHYDROGENATION PROCESS

A process for the catalytic dehydrogenation of a C3+ feed hydrocarbon. The hydrocarbon feedstock is initially divided and a first portion of the feedstock is introduced into a first dehydrogenation reaction zone operated without oxidative reheat and the resulting effluent is introduced into a second...

Zusammenfassung:	A process for the catalytic dehydrogenation of a C3+ feed hydrocarbon. The hydrocarbon feedstock is initially divided and a first portion of the feedstock is introduced into a first dehydrogenation reaction zone operated without oxidative reheat and the resulting effluent is introduced into a second dehydrogenation reaction zone operated without oxidative reheat. The resulting effluent from the second dehydrogenation reaction zone is introduced along with a second portion of the feedstock into a third dehydrogenation reaction zone operated with oxidative reheat.
