PROCESS FOR PREPARING IRON-BASED CATALYSTS FOR THE SYNTHESIS OF AMMONIA AND CATALYSTS SO OBTAINED

摘要

ABSTRACT OF THE DISCLOSUREA process for preparing iron-based catalysts for thesynthesis of ammonia by melting of magnetite along with metal ox-ides as promotors, subsequent cooling of the molten mass and re-duction thereof to the desired size, wherein the abovesaid cool-ing occurs at a rate higher than 25°C/min., preferably rangingfrom 100°C to 1600°C/min., at a temperature ranging from 1700°Cto 700°C.
