Direct synthesis of methyl acetate and acetic acid from syngas over tandem catalysts composed of a Cu-based catalyst and a Cu-exchanged mordenite zeolite

Key Points

• To explore the direct conversion of syngas into methyl acetate and acetic acid using tandem catalysts.
• Utilized a Cu-based catalyst for methanol synthesis.
• Employed a mordenite zeolite as a DME carbonylation catalyst.
• Conducted reactions at 230 °C and 5 MPa.
• Achieved high selectivity for methyl acetate and acetic acid production from syngas.
• Optimized reaction conditions led to efficient usage of tandem catalysts.
