Co-Activation of CH4 and CO2 for Acetic acid over Cu-Loaded catalysts = Co-Activation of CH4 and CO2 for Acetic acid over Cu-Loaded catalysts

다국어 초록 (Multilingual Abstract)

Cu nanoparticles were loaded onto NaZSM-5 and proven to form acetic acid by the co-feed of methane and carbon monoxide in a continuous flowed fixed-bed microreactor. Considerable yield on acetic acid were obtained via one-step reaction without cyclic or two-step reaction by feeding methane and CO2 alternatively in overall reaction temperatures between 425 to 525°C, and 5x10(4) μmol.gcat-1 of acetic acid was obtained at 525 °C with CO2/CH4 having molar ratio of 2.75, and 360 ml hr-1 of space velocity based on methane. Reduced Cu exchanged Na-ZSM5 catalyst exhibited superior formation rate of acetic acid than Cu ion exchanged NaZSM-5 and Cu-HZSM-5 catalysts. Hence, the supported Cu nanoparticles NaZSM-5 catalyst could enable activate both CO2 and CH4 simultaneously to give acetic acid in a continuous reaction mode.
