摘要： 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.
