A STUDY ON THE DIRECT CONVERSION OF METHANE TO METHANOL

The selective oxidation of methane to methanol has been investigated in a packed bed reactor applying V205/SiO2 as the reaction catalyst. The effects of certain pertinent parameters of the system such as temperature, pressure and gas hourly space velocity (GHS V) on the conversion of methane and sel...
