PROCESS OF SELECTIVELY HYDROGENATING GAS MIXTURE HAVING HIGH ACETYLENE CONTENT

Title:

PROCESS OF SELECTIVELY HYDROGENATING GAS MIXTURE HAVING HIGH ACETYLENE CONTENT

Document Type and Number:

Japanese Patent JP2023065340

Kind Code:

A

Abstract:

To provide a method of producing ethylene at high yield through selective hydrogenation of a gas mixture containing high-concentration acetylene resulting from a methane pyrolysis process, and a method of effectively recovering or utilizing hydrogen.SOLUTION: Methane is converted into value-added compounds such that a gas mixture containing hydrogen and high-concentration acetylene formed through methane pyrolysis (e.g., non-oxidative coupling of methane) reaction or the like is selectively hydrogenated in the presence of a bimetallic supported catalyst, producing ethylene from acetylene in the gas mixture while recovering and/or additionally recycling unreacted methane and hydrogen as byproducts.SELECTED DRAWING: Figure 1
