Abstract
Catalytic conversion of a C.sub.2 -C.sub.5 alkane, e.g., isobutane and/or isopentane, to isoalkenes, e.g., isobutene and/or isopentene, respectively, is undertaken in the presence of an aromatic recycle stream which provides the heat of reaction for the conversion which is endothermic, in the absence of hydrogen.
