Method for preparing catalytic cracking catalyst utilizing fine powder of catalyst

The method for preparing catalytic cracking catalyst by using catalyst fine powder includes the following steps: (1) using catalyst fine powder, whose grain size is less than 20 micrometers and beating with water, uniformly stirring slurry and grinding by means of grinding machine to make average grain size of catalyst fine powder be less than 1.5 micrometers; (2). mixing the above-mentioned slurry, natural clay, adhesive and molecular sieve slurry and beating to obtain collod material; and (3) drying and forming by using spray-drying equipment. 一种利用催化剂细粉制备催化裂化催化剂的方法，其特征在于该方法包括以下步骤：(1).将粒径小于20μm的催化剂细粉与水打浆，浆液搅拌均匀后送入砂磨机研磨，使催化剂细粉的平均粒径小于1.5μm；(2).将步骤(1)所得浆液、天然粘土、粘结剂以及分子筛浆液混合打浆；(3).步骤(2)所得胶体送入喷雾干燥装置干燥成型。采用该方法可降低生产成本、充分利用资源。
