  • Use of methane pyrolysis to decarbonize a hydrocarbon cracking system
    Patent number: 11958745
    Abstract: Processes and systems that utilize methane pyrolysis for carbon capture from a petrochemical stream that contains hydrogen and methane. The petrochemical stream can be the tail gas of a hydrocarbon cracking system, or any other petrochemical stream containing hydrogen and methane. The petrochemical stream can be separated into a hydrogen product stream and a methane product stream, before sending the methane product stream to a methane pyrolysis unit. The methane pyrolysis unit converts methane to solid carbon and hydrogen.
