Born Jan. 11, 1892, in Novara; died there Dec. 7, 1971. Italian chemist.
Fauser graduated from the Milan Polytechnic Institute in 1913. In 1921 he began working for the Italian firm of Montecatini, and in 1932 he founded a scientific research institute in Novara.
Fauser’s principal works deal with methods for the production of ammonia, nitric acid, ammonium sulfate, and urea. In 1920 he set up the first installation for the synthesis of ammonia under a pressure of 25–30 meganewtons per sq m (250–300 atmospheres). In 1922 the firm of Montecatini began constructing plants for the production of ammonia through the Fauser method in Italy and other countries.
