Zusammenfassung:Olefins may be produced from C4-C6 saturated hydrocarbons by systems and methods comprising passing a feed comprising C4-C6 saturated hydrocarbons and hydrogen into a dehydrogenation unit to produce a dehydrogenation effluent, passing at least a portion of the dehydrogenation effluent into a hydrogenation unit to produce a hydrogenation effluent, and passing at least a portion of the hydrogenation effluent into a cracking unit to produce a cracking effluent comprising olefins. The dehydrogenation unit includes a dehydrogenation catalyst, the hydrogenation unit includes a hydrogenation catalyst, and the cracking unit includes a cracking catalyst.
