A METHOD FOR PREPARING CATALYZING BLOCKS FOR AMMONIA SYNTHESIS COLUMNS by mixing fine-grained, iron catalyst with a solution of rum mineral binder based on aluminate metals, compaction; and calcining it, so that the purpose of obtaining catalyst blocks higher mechanical strength and higher performance, as used as a binder An aqueous solution of calcium aluminate is used in a ratio of calcium aluminate: water from 1: 1 to 1: 9, and after calcination, the water is treated with steam: at 150-300 seconds and dried at 150200 ° C.
