The reactivity of Co(1.5)PW(12)O(40) in the direct synthesis of dimethyl carbonate (DMC) from CO(2) and CH(3)OH was investigated. The synthesized catalyst has been characterized by means of FTIR, XRD, TG, and DTA and tested in gas phase under atmospheric pressure. The effects of the reaction temperature, time on stream, and methanol weight hourly space velocity (MWHSV) on the conversion and DMC selectivity were investigated. The highest conversion (7.6%) and highest DMC selectivity (86.5%) were… CONTINUE READING
