1750. ----------------. [KHRIZMAN, I. A.] [Stabilization of Reduced Catalyst for Ammonia Synthesis.] Ber. Pissarjewsky Inst. Physik. Chem., Akad. Wiss. Ukr. S. S. R., vol. 12, 1940, pp. 15-20; Chem. Abs., vol. 35, 1941, p. 2685.

NH₃ catalyst of the type Fe-Al₂O₃-K₂O was 1^st reduced with a dry mixture of H₂ and N₂ and then nitrided with dry NH₃. The temperature interval for reduction and nitriding was 350°-475°. The nitrided catalyst was cooled in a stream of NH₃ and tested for stability (reaction with moisture, CO₂ and O₂). The tests indicate that the stabilized catalyst may be transported from the place of manufacture to the NH₃ synthesis plant without loss of activity.
