Effect of Mn and Pb Promoters on the Performance of Cu/ZnO-Catalyst in CO₂ Hydrogenation to Methanol

Abstract:

The influences of Mn or Pb promoters on the catalytic performance of Cu/ZnO-SBA-15 catalyst in the methanol synthesis from CO₂ hydrogenation were studied. The catalytic performances of the prepared catalysts were investigated in a stirred high pressure reactor under conditions of T = 483K, P = 2.25 MPa, and H₂:CO₂ = 3:1 (volume ratio). The experimental results showed that the promoted catalysts exhibited higher catalytic performance. The Mn promoted catalyst resulted in 36% of CO₂ conversion and 67% of methanol selectivity, whereas the unpromoted catalyst showed 26% of CO₂ conversion and 58% of methanol selectivity.
