Carbon Monoxide Hydrogenation on SiO2-, Al2O3-, or TiO2-Attached Nb-Monomer Catalysts

Article abstract of DOI:10.1246/cl.1987.573

The new low-valent Nb monomer catalysts which were prepared by taking advantage of the reaction between Nb(^ν3-C3H5)4 and surface OH groups on SiO2, Al2O3, or Tio2, followed by the treatments with H2, were found to be active for the hydrogenation of carbon monoxide in which C2-C4 hydrocarbons were mainly produced in the temperature range 423-598 K.In contrast, only the disproportionation reaction of CO to form CO2 proceeded on usual impregnation Nb catalysts and Nb2O5.
