Filed: 2019-10-21
Abstract: A method for preparing a cerium silicon composite oxide, and a product and an application thereof. According to the method, ceric ammonium nitrate and tetraethyl orthosilicate (TEOS) are mixed and dissolved in ethyl alcohol, then under a stirring condition, stronger ammonia water is dropwise added until precipitation is complete, and then the cerium silicon composite oxide is obtained through ageing, filtering, washing, drying and calcining. Compared with pure CeO 2 , the cerium silicon composite oxide has a larger specific surface area, higher acidity, and a special surface adsorption mechanism, and the activity of CeO 2  for catalyzing an NH 3 -SCR reaction is effectively improved. The cerium silicon composite oxide serves as a flue gas denitration catalyst, and has better medium and low temperature activity, high N 2  selectivity, superior sulfur poisoning resistance, and environmental friendliness. The method for preparing the cerium silicon composite oxide is simple, raw materials are simple and easy to obtain, and the cerium silicon composite oxide can be produced in a large scale and has a broad industrial application prospect.
