They demonstrated their process in the summer of 1909 by producing ammonia from air, drop by drop, at the rate of about per hour.
Under Bosch's direction in 1909, the BASF researcher Alwin Mittasch discovered a much less expensive iron-based catalyst, which is still used today. During the interwar years, alternative processes were developed, the most notably different being the Casale process and Claude process.
He succeeded in 1910.
Haber and Bosch were later awarded Nobel prizes, in 1918 and 1931 respectively, for their work in overcoming the chemical and engineering problems of large-scale, continuous-flow, high-pressure technology. Ammonia was first manufactured using the Haber process on an industrial scale in 1913 in BASF's Oppau plant in Germany, reaching 20 tonnes per day the following year.
