Abstract

A process and apparatus for dehydrogenating alkanes such as iso-butane comprises contacting the alkane in admixture with steam under dehydrogenation conditions with a dehydrogenation catalyst. The catalyst is substantially free of Group VIII metals of Atomic Number 27 and higher. The catalyst is provided in a heated tubular reactor which preferably contains groups of tubes mounted in a furnace each group of tubes having a common header, to enable continuous dehydrogenation, while permitting catalyst reactivation.
