BLOCK CATALYZER PREPARATION CONTAINING FERRIC OXIDE ACTIVATED BY PROMOTER AND APPLICABLE AT AMMONIA SYNTHESIS AND PROCESS FOR PRODUCING SAME

摘要

Block of granular promoted Fe oxide catalyst for NH3 synthesis contains granular promoted Fe oxide catalyst (I), a metal aluminate (II) and reinforcing elements (III). The novelty is that the block contains an alkaline earth metal aluminate and (II) and has the compsn. 84.0-04.5 (wt.)%(I), 5.0-15.0% (II) and 0.5-1.0% (III). - The block is produced by mixing (I) with (III) in aq. medium, using a (II) : water wt. ratio of 1:1-9, moulding, with insertion of (III), thermal treatment at 200-600 deg.C, hydrothermal treatment at 150-300 deg.C, and then drying at 150-200 deg.C.
