Abstract

Hydrogen or mixtures of nitrogen and hydrogen are obtained by treating with steam and in the presence of a catalyst the gases from electric and blast smelting-furnaces, and subsequently eliminating the steam, carbon monoxide and carbon dioxide; hydrogen is obtained if the gases treated are those from electric smelting-furnaces or from blast furnaces fed with oxygen; in other cases, a mixture of nitrogen and hydrogen is obtained, the relative proportions of the two constituents depending on whether the furnace is blown with air or air enriched with oxygen. The hydrogen obtained from electric furnace, &c., gases may be mixed with the poorer mixture from blast furnace gases, or with nitrogen; also, this poorer mixture may be mixed with hydrogen. The gases after reaction with steam are passed through water scrubbers to remove the excess of steam, and then treated with alkali or alkali earth substances or with water under pressure to remove carbon dioxide; traces of carbon monoxide and carbon dioxide are removed by caustic soda, copper salts, &c. When suitably purified, the gases may be used in the hydrogenation of fats, the synthesis of ammonia, as fuel for internal combustion engines, and for welding.
