A process for producing olefins comprising introducing butane feed (n-butane, i-butane) and hydrogen to hydrogenolysis reactor comprising hydrogenolysis catalyst to produce a hydrogenolysis product stream (hydrogen, methane, ethane, propane, i-butane, optionally n-butane, optionally C.sub.5+ hydrocarbons); and feeding the hydrogenolysis product stream and hydrogen to hydrocracking reactor comprising a hydrocracking catalyst to produce hydrocracking product stream (hydrogen, methane, ethane, propane, i-butane, optionally n-butane), wherein the amount of i-butane in the hydrocracking product stream is less than in the hydrogenolysis product stream, and wherein the amount of ethane in the hydrocracking product stream is greater than in the hydrogenolysis product stream. The hydrocracking product stream is separated into first hydrogen stream, first methane stream, first C.sub.2+ gas stream (ethane, propane), first C.sub.4s stream (i-butane, optionally n-butane), optionally C.sub.5+ stream; and the first C.sub.2+ gas stream is fed to gas steam cracker to produce a steam cracker product stream comprising olefins (ethylene, propylene).

This application relates to transfer hydrogenation between light alkanes and olefins, and, more particularly, embodiments related to an integrated olefin production system and process which can produce higher carbon number olefins from corresponding alkanes. Examples methods may include reacting at least a portion of the ethylene and the at least one alkane via transfer hydrogenation to produce at least a mixed product stream comprising generated ethane from at least a portion of the ethylene, unreacted ethylene, and an olefin corresponding to the at least one alkane.

This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C.sub.5 hydrocarbons to cyclopentadiene in a reactor system. The process includes heating an electrically-conductive reaction zone by applying an electrical current to the first electrically-conductive reaction zone; and contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in the electrically-conductive reaction zone under reaction conditions to convert at least a portion of the acyclic hydrocarbons to an effluent comprising alkenes, cyclic hydrocarbons, and/or aromatics.
