一种SCR蜂窝脱硝催化剂的混炼工艺
摘要：
本发明涉及一种SCR蜂窝脱硝催化剂的混炼工艺，属于脱硝催化剂领域，提高破损催化剂的使用率，降低破损催化剂的回收利用成本。一种SCR蜂窝脱硝催化剂的混炼工艺，包括如下步骤：a.将破损催化剂和水加入搅拌机中搅拌，搅拌速度为80r/min-120r/min，搅拌时间为10min-15min，以使催化剂软化；b.将润滑剂、增塑剂、粘结剂加入搅拌机中继续搅拌，搅拌速度为400r/min-600r/min，搅拌时间为5min-10min，得到SCR蜂窝脱硝催化剂的混炼料；其中，所述润滑剂为甘油或三乙醇胺，所述增塑剂为邻苯二甲酸二辛酯或邻苯二甲酸二丁酯，所述粘结剂为聚乙烯醇、羧丙基甲基纤维素中的一种或两种。
摘要（英）：

The invention relates to a mixing process for an SCR honeycomb denitration catalyst, and belongs to the field of denitration catalysts, which improves the utilization rate of damaged catalysts and lowers the recycling cost of damaged catalysts. The mixing process for the SCR honeycomb denitration catalyst comprises the steps of a, adding a damaged catalyst and water in a blender to obtain a mixture, and stirring the mixture at the speed of 80r/min-120r/min for 10-15 min so as to soften the catalyst; b, adding a lubricant, a plasticizer and a binder in the blender and further stirring the mixture at the speed of 400 r/min-600r/min for 5-10 min so as to obtain the mixed material of an SCR honeycomb denitration catalyst. The lubricant is selected from glycerol or tri-ethanolamine. The plasticizer is selected from dioctyl phthalate or di-butyl phthalate. The binder is one or two selected from polyvinyl alcohol and hydroxypropyl methyl cellulose.
