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.

The effect of particle size (0.33-1.0 mm) of the sodium carbonate on the reactivity of the active sodium carbonate prepared therefrom towards the sulfur dioxide was studied in a fixedbed integral reactor at a temperature of 150 °C. The found dependence of the reaction rate on the particle size exhibits an unexpected course; at sizes of about 0.65 mm, a distinct minimum appears. The reaction rate decreases approximately ten times in the first branch of this dependence. The controlling factor of the reactivity of sodium carbonate, however, remains to be the method of preparing the active form.
