一种钢渣陶粒催化剂及其制备方法
摘要：
本发明公开了一种钢渣陶粒催化剂及其制备方法。其技术方案是：将15~27wt%的钢渣、15~35wt%的黏土、20~28wt%的粉煤灰、15~25wt%的剩余活性污泥和5~15wt%的催化剂活性组分混合，烘干，研磨；将研磨后的催化剂混合料放入圆盘造粒机，在转动条件下向所述催化剂混合料喷洒水，水的喷洒量为所述催化剂混合料的8～10wt%，转动圆盘造粒机至所述催化剂混合料形成粒径为3~5mm的球状催化剂颗粒；将所述球状催化剂颗粒于100~105℃条件下烘干；再于1050~1200℃条件下烧结20~30分钟，制得钢渣陶粒催化剂。本发明具有成本低、环境友好和资源化程度高的特点，所制备的钢渣陶粒催化剂的活性组分稳定性好和催化活性高。
摘要（英）：

The invention discloses a steel slag based ceramsite catalyst and a preparation method thereof. The technical scheme is that the preparation method comprises the following steps: 15wt%-27wt% of steel slag, 15wt%-35wt% of clay, 20wt%-28wt% of fly ash, 15wt%-25wt% of excess activated sludge and 5wt%-15wt% of catalyst active components are mixed, dried and ground; the ground catalyst mixture is fed into a disc granulator, water is sprayed to the catalyst mixture under rotating condition, the spraying amount of water is 8wt%-10wt% of the catalyst mixture, the disc granulator rotates until spherical catalyst granules with granule size being 3-5 mm are formed from the catalyst mixture, and the spherical catalyst granules are dried at 100-105 DEG C; the spherical catalyst granules are sintered for 20-30 min at 1050-1200 DEG C, and the steel slag based ceramsite catalyst is prepared. The preparation method has the characteristics of being low in cost, environment-friendly and high in recycling degree, and the prepared steel slag based ceramsite catalyst has good active component stability and high catalytic activity.
