Denitration catalyst applied to cement plant and preparation method of denitration catalyst

The invention discloses a denitration catalyst applied to a cement plant. The denitration catalyst is prepared from the following raw materials in parts by weight: 10-20 parts of carbon black, 10-20 parts of paraffin wax, 20-45 parts of montmorillonite, 10-15 parts of iron-based transition metal composite oxide, and 5-10 parts of transition rare metal and oxide. In addition, the invention furtherdiscloses a preparation method of the denitration catalyst. The preparation method comprises the following steps that (1) raw material powders in parts by weight is obtained; and (2) all the raw material powders are mixed and stirred to obtain the denitration catalyst. The denitration catalyst can greatly reduce the use amount of ammonia water or completely replace the ammonia water, and can meetthe goal of ultra-low emission of nitrogen oxides in the cement plant, thereby realizing real ammonia-free denitration. 本发明公开了一种应用于水泥厂的脱硝催化剂，包括如下重量份的原材料制成：炭黑10-20份、石蜡10-20份、蒙脱土20-45份、铁为主的过渡金属复合氧化物10-15份、过渡稀有金属及氧化物5-10份。此外，本发明还
