Abstract
Molybdenum catalysts used in the synthesis of hydrocarbons can be prepared by reduction of molybdenum trioxide with hydrogen to form water at elevated temperatures. When carbon is used as the catalyst support material the possibility exists for the reduction of the metal oxide by the carbon support which would produce carbon dioxide. Thermogravimetry/mass spectrometry (TG-MS) was utilized in this study to quantitate the amount of reduction of the molybdenum oxide by hydrogen and by the carbon support up to 700°C. Results show that in an inert atmosphere such as helium a significant amount of reduction is effected by the carbon support. However, in a 5% hydrogen/95% helium atmosphere reduction of the oxide by hydrogen predominates with less than 2% reduction occurring via the carbon support.
