Disclosed is a method for producing hydrogen, carbon, and ethylene from a methane-containing feedstock even without recycling of unreacted methane by providing a single process or system in which a methane-containing feedstock is subjected to two methane conversion steps. The method includes a first conversion step of producing hydrogen and carbonaceous materials and a second conversion step of producing acetylene from unreacted methane and hydrogen discharged from the first conversion step while maintaining a good methane conversion and suppressing coke formation, followed by separating and recovering ethylene and hydrogen produced through selective hydrogenation of acetylene.

Disclosed is a process for converting methane into value-added compounds. In this process, a gas mixture containing hydrogen as well as high-concentration acetylene formed through methane pyrolysis (e.g. non-oxidative coupling of methane) is selectively hydrogenated in the presence of a bimetallic supported catalyst. This process obtains ethylene from acetylene in the gas mixture while unreacted methane and hydrogen are recovered as byproducts and/or additionally recycled.
