Methanol Synthesis Using Copper Catalysts Supported on CeO2−Al2O3 Mixed Oxide

  • Published:
Fibre Chemistry Aims and scope

Results are given for a study of the catalytic and physicochemical properties of monometallic Cu/CeO2-Al2O3 and bimetallic Pd-Cu/CeO2-Al2O3 catalysts for the synthesis of methanol from hydrogen and carbon dioxide. The catalytic activity was determined in methanol synthesis in a gradientless reactor at 200°C and 3.5 MPa. The physicochemical properties of these catalytic systems were studied by the BET method (Brunauer−Emmett− Teller method), temperature-programmed reduction of hydrogen (TPR-H2), temperature-programmed desorption of ammonia (TPD-NH3), x-ray diffraction (XRD), and Fourier-transform IR spectroscopy (FTIR). Our results showed high activity for the palladium-promoted catalyst, which is attributed to a synergistic effect between palladium and copper as well as the formation of a PdCu alloy during activation of this bimetallic catalyst in a reducing atmosphere of 5% H2 95% Ar.

Notes

  1. The spillover effect is displacement of the excited hydrogen atom from the metal surface to the catalyst surface.
