Embodiments disclosed herein related to processes and systems for alkane aromatization. In some embodiments, the process includes merging a benzene-containing stream into an ethane containing stream to form a feed stream. The feed stream has at least 5 wt. % benzene based on the total weight of the feed stream. In addition, the process includes contacting the feed stream with an aromatization catalyst to produce an effluent stream comprising C.sub.7+ aromatic hydrocarbons. Less than 5 wt. % net benzene is produced during the contacting, based on a total weight of the feed stream.

Disclosed is a hydrocarbon conversion process in which an alkane component is catalytically converted in the presence of an oxygen or oxidizing component (i.e., oxidant). The hydrocarbon conversion process can be an oxidative coupling reaction, which refers to the catalytic conversion of alkane in the presence of oxidant to produce an olefin product, i.e., a composition containing C.sub.2+ olefin. Reverse-flow reactors can be used to carry out the oxidative coupling reaction.

Processes are provided for conversion of oxygenated hydrocarbon, such as methanol and/or dimethyl ether, to aromatics, such as a para-xylene, and olefins, such as ethylene and propylene. The processes entail using a reactor having multiple reaction zones where each zone is prepared to promote desired reactions.
