测定拟薄水铝石中碳酸根含量的方法和胶溶酸用量的方法以及催化裂化催化剂的制备方法
摘要：
本发明涉及催化剂制备领域，公开了一种测定拟薄水铝石中碳酸根含量的方法，一种确定拟薄水铝石胶溶酸用量的方法和一种催化裂化催化剂的制备方法。确定拟薄水铝石胶溶酸用量的方法包括：测定所述拟薄水铝石中的碳酸根含量C碳酸根和所述拟薄水铝石的干基含量w干，按照式(II)的方法计算所述胶溶酸用量：S＝S酸铝比+102×C碳酸根÷(w干×60×Z)，式(II)，其中，相对于以氧化铝计的1mol的拟薄水铝石，胶溶酸用量为S mol；S酸铝比为0.15-0.25；Z为1或2。本发明提供的确定含碳酸根拟薄水铝石胶溶酸用量的方法更为简单，更为准确，重复性好，可稳定产品质量。
摘要（英）：

The invention relates to the field of catalyst preparation, and discloses a method for determining the carbonate content of pseudo-boehmite, a method for determining the usage amount of peptizing acidfor the pseudo-boehmite and a preparation method for a catalytic cracking catalyst. The method for determining the usage amount of the peptizing acid for the pseudo-boehmite comprises the following steps: determining the carbonate content C of the pseudo-boehmite and the dry-basis content w of the pseudo-boehmite, and calculating the usage amount of the peptizing acid according toan equation as shown in a formula (II) (S = (S + 102*C)/(w*60*Z), wherein in the formula (II), the usage amount of the peptizing acid relative to 1 mol of thepseudo-boehmite in terms of alumina is S mol; S is in a range of 0.15 to 0.25; and Z is 1 or 2. The method for determining the usage amount of the peptizing acid for carbonate-containing pseudo-boehmite provided by the invention is simpler and more accurate, has good repeatability, and can stabilize the quality of a product.
