Methane Pyrolysis
Through plasma, catalysis or molten media cracking, methane is decomposed into H₂ and carbon materials such as carbon nanotubes and graphene. The solids are collected by filtration, and the generated H₂ is purified by palladium membrane to remove the methane and byproducts (acetylene, ethylene, and ethane etc.), achieving a H₂ purity >99.999%. Although methane cracking achieves high conversion rates, it typically operates at low or atmospheric pressure; therefore compression is applied prior to H₂ separation to enhance the separation efficiency.
