Preparation method for improving strength of catalytic cracking waste catalyst geopolymer
The invention provides a mixing method for improving the strength of a catalytic cracking waste catalyst geopolymer, which comprises the following steps: by using a catalytic cracking waste catalyst as a raw material, adding a solid reinforcing agent and an alkali activator to regulate the reaction activity; and achieving crushing of the catalytic cracking waste catalyst, the solid reinforcing agent and the alkali activator and mixing of materials in a stirring mill, a mixing mill or a colloid mill, and then conducting forming and maintenance to form the geopolymer . According to the present invention, the FCC waste catalyst is crushed in the stirring mill, the mixing mill or the colloid mill while the FCC waste catalyst and other materials are completely mixed, such that the equipment number is reduced, the complete mixing on the small scale is achieved, and the geopolymer with the high mechanical strength is obtained. The formed geopolymer inorganic material has a unique three-dimensional network structure, toxic and harmful substances such as heavy metal ions can be segmented and surrounded in the geopolymer inorganic material, and the process is simple in flow, low in cost andgood in harmless effect.
本发明提供了一种提高催化裂化废催化剂地质聚合物强度的混合方法，包括以下步骤：以催化裂化废催化剂为原料，加入固体增强剂和碱激发剂调控其反应活性，在搅拌磨、混碾机或胶体磨中完成催化裂化废催化剂、固体增强剂和碱激发剂的粉碎和物料间的混合，然后经成型、养护形成地质聚合物。本发明提出在搅拌磨、混碾机或胶体磨中实现FCC废催化剂的粉碎，同时实现FCC废催化剂和其它物料的充分混合，不仅减少设备数量，且实现更小尺度上的充分混合，得到具有更高机械强度的地质聚合物，所形成的地质聚合物无机材料具有独特的三维网状结构，可将重金属离子等有毒有害物质分割包围在其中，该工艺流程简单、成本低、无害化效果好。
