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.

Process for producing hydrogen, carbon, and ethylene from methane-containing feedstock

A platform server includes at least one memory configured to store instructions for performing a predetermined operation, and at least one processor operatively connected to the memory and configured to execute the instructions. The at least one processor is configured to store data in which carbon emissions are defined for each manufacturing weight of bicycle parts made of a predetermined material, acquire an image of a bicycle, determine parts included in the image, determine carbon emissions according to manufacturing of the bicycle by comparing information on the determined parts with the defined data, and provide mileage to a subject related to an event based on the determined carbon emissions when the event related to the bicycle corresponding to the image occurs.

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.
