Abstract

245,762. Soc. d'Etudes MiniÞres et Industrielles. Jan. 8, 1925, [Convention date]. Ammonia, catalytic production of; catalytic agents, preparation of. - The Specification as open to inspection under Sect. 91 (3) (a) describes the synthesis of ammonia by passing a mixture of nitrogen and hydrogen at any pressure (even atmospheric) and at a temperature of 550-600‹ C. over a mixture of a metal of the iron group, a nitrogen compound of lithium, and an oxide of a metal of the aluminium group. This subjectmatter does not appear in the Specification as accepted.
