Abstract
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 Chydrocarbons); 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 Cgas stream (ethane, propane), first Cs stream (i-butane, optionally n-butane), optionally Cstream; and the first Cgas stream is fed to gas steam cracker to produce a steam cracker product stream comprising olefins (ethylene, propylene).
