Patent Abstracts

Coal, hydrocarbons, or C are hydrogenated by the action of an electric arc or sparks from a condenser discharge between electrodes immersed in a solvent for the products. One electrode is made of, or contains, a catalytically active metal such as Ni or contains a salt such as NiCO₃, which becomes dispersed in the liquid. Gives examples of the hydrogenation of coal and water gas.
