Formed red mud catalyst, and preparation method and application thereof

The invention provides a formed red mud catalyst, and a preparation method and an application thereof. The formed red mud catalyst is prepared from the following raw materials: red mud and a forming auxiliary agent, wherein the forming auxiliary agent comprises a binder which is one or more selected from the group consisting of guar gum, sesbania powder and CMC. The catalyst provided by the invention is easy to form, has good catalytic denitration activity, has good denitration efficiency at 275-450 DEG C, and has longer active temperature interval than acid pickling red mud. 本发明提供一种成型赤泥催化剂及其制备方法和应用，该成型赤泥催化剂，其原料包括赤泥和成型助剂，其中，所述成型助剂包括粘结剂，所述粘结剂选自瓜尔胶、田菁粉和CMC中的一种或多种。该催化剂易于成型，且具有较好的催化脱硝活性，在275-450℃均具有较好的脱硝效率，比酸洗赤泥拥有更长的活性温度区间。
