Molybdic Oxide

The action of five suspension media and various catalysts in the hydrogenation of coal has been investigated. It has been shown that the Alberta coals used may be hydrogenated successfully. The properties of the medium have been found to be a controlling factor in the process. The effectiveness of the different media varied with the ease with which they could be hydrogenated and dehydrogenated. Tetrahydronaphthalene was found to be much superior to other media, and showed a greater effect than could be attributed to any of the catalysts used. Experiments showed that this compound was effective because of its action as a hydrogen carrier. Of the catalysts used, molybdic oxide and a mixture of iron and chromium oxides were most effective. The details of the reactions are discussed briefly.

On passing natural gas, containing 4.8% ethane, through an electrically heated tungsten spiral, the formation of liquid products was observed at 1050 °C.On passing the same gas over an electrically heated 4-mm. carbon rod enclosed in an uninsulated silica tube 2.0 cm. wide, 7.7% of the gas was converted to liquid and solid hydrocarbons at a rod temperature of 1050–1100 °C. No liquids or solids except carbon were formed when the silica tube was insulated.By replacing the 2.0-cm. silica tube by a water-cooled Pyrex tube, 3.2 cm. wide, no liquid or solid hydrocarbons were obtained, but 17% of the gas was converted to gaseous unsaturated hydrocarbons at 993 °C. On passing ethane through the 3.2-cm. water-cooled reaction tube at rod temperature of 989 °C., 50.5% of the entering gas was converted to ethylene, and 90.0% of the ethane decomposed did so according to the equation C2H6 → C2H4 + H2.The dehydrogenation of ethane was found to be greatly accelerated by the presence of reduced copper in the tube, the metal being used in the form of a cylindrical wire gauze and placed around the carbon rod. Copper bronze coated with molybdic oxide was also found to be active under the same conditions.
