A process for producing methyl tert-butyl ether (MTBE) comprising introducing a butane feed stream (n-butane, i-butane) and hydrogen to a hydrogenolysis reactor comprising a hydrogenolysis catalyst to produce a hydrogenolysis product stream comprising hydrogen, methane, ethane, propane, i-butane, and optionally n-butane; separating the hydrogenolysis product stream into a first hydrogen-containing stream, an optional methane stream, a Cto Cgas stream (ethane, propane), and a butane stream (i-butane, optionally n-butane); feeding the butane stream to a dehydrogenation reactor to produce a dehydrogenation product stream, wherein the dehydrogenation reactor comprises a dehydrogenation catalyst, and wherein the dehydrogenation product stream comprises hydrogen, i-butane, and isobutylene; and feeding the dehydrogenation product stream and methanol to an etherification unit to produce an unreacted methanol stream, an unreacted isobutylene stream, and an MTBE stream.

Selective hydrogenolysis integrated with MTBE production

A hydrogenolysis bimetallic supported catalyst comprising a first metal, a second metal, and a zeolitic support; wherein the first metal and the second metal are different; and wherein the first metal and the second metal can each independently be selected from the group consisting of iridium (Ir), platinum (Pt), rhodium (Rh), ruthenium (Ru), palladium (Pd), molybdenum (Mo), tungsten (W), nickel (Ni), and cobalt (Co).

Bimetallic catalysts supported on zeolites for selective conversion of n-butane to ethane

Processes for the hydrogenolysis of butane are described. A process can include (a) introducing a butane feed and hydrogen to a first hydrogenolysis reactor comprising a hydrogenolysis catalyst, and (b) contacting the butane feed and hydrogen with the hydrogenolysis catalyst at conditions sufficient to produce a first hydrogenolysis product stream. The introduction of the butane feed stream and hydrogen to the first hydrogenolysis reactor can be controlled to maintain a hydrogen to butane molar ratio in the reactor inlet of 0.3:1 to 0.8:1.

Methods of butane hydrogenolysis under hydrogen-lean conditions

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).
