Abstract

288,154. Kali-Industrie Akt.-Ges., and Thorssell, T. April 1, 1927, [Convention date]. Hydrogen; nitrogen.-Nitrogen and hydrogen for ammonia, synthesis are obtained by passing air and steam successively over iron or ferrous oxide, the higher oxides produced being next treated in the same chamber with reducing gases, the operations being carried out repeatedly without the use of a separate heat supply. The oxidation and reduction of the iron is regulated so that about a quarter of the reaction proceeds between the ferrous and ferric oxides, about one half between the ferrous and magnetic oxides, and about a quarter between the magnetic and ferric oxides. The heat produced in the oxidation of the iron oxides is retained in the apparatus by insulating the reaction chamber, which is of considerable heat-storing capacity, and using heat exchanges between the gases entering and leaving the chamber, and may be regulated by varying the amount of the insulation and the action of the heat exchangers. The reducing gases may be water gas or coke or blast furnace gas. If a poor reducing gas is used, the amount of nitrogen produced must be increased. The waste reducing gases can be burnt to raise the steam required in the process and to produce heat for the ammonia synthesis. Examples are given in the Specification.
