Then in 1914 Fritz Haber, clever German necromancer, found that nitrogen gas can be captured in another way-by combining it with hydrogen to form ammonia. Instead of electricity, the Haber process makes use of an agent called a "catalyst," which is a substance that by its mere presence causes the union of two other elements. Efficient catalysts, or as Dr. E. E. Slosson calls them, the "good mixers" of chemical society, are expensive. Haber used uranium, platinum or some other rare and finely divided metal. When the nitrogen and hydrogen, after being elaborately purified, mixed in proper proportions, compressed...

...nitrogen research laboratory of the Chemical Warfare Service of the U. S. Army, at Washington, by Dr. Arthur B. Lamb, director of the laboratory, and professor of chemistry at Harvard University. A new catalyst has been found to unite the atoms of nitrogen and hydrogen into the molecule of ammonia. It yields 14% of ammonia, twice the amount given by the Haber process. The nature of the catalyst was not announced, but it has far greater durability, and will make possible explosives and fertilizers both more effective and much cheaper than any now existing...

...contact material, or catalyst, as it is called, which causes the nitrogen in the air to combine with other substances, especially hydrogen, with greater case and efficiency than has hitherto been the case. Where the catalysts used in other processes will produce 7 or 8 percent of ammonia, this new compound will yield 14 percent, and it has been run continuously for six months without deterioration...

...temperature system invented by Charles C. Bussey, of New York, is in successful operation at Louisville, Ky. It differs in method from the Piron system, but gives somewhat similar results. It utilizes inferior bituminous coal and oil shale, and yields by-products of fuel oil, gas, ammonia and benzol, while eliminating sulphur and phosphorus from the coke...
