High-adsorption and high-compression-resistance molecular sieve and preparation method thereof

The invention discloses a high-adsorption and high-compression-resistance molecular sieve. The high-adsorption and high-compression-resistance molecular sieve comprises an aluminosilicate molecular sieve, a yttrium-regulated and modified bentonite agent and a hydroxyapatite regulator, wherein the substance mass ratio of the aluminosilicate molecular sieve to the yttrium-regulated and modified bentonite agent to the hydroxyapatite regulator is (5-7): (2-4): 1. According to the high-adsorption and high-compression-resistance molecular sieve disclosed by the invention, the aluminosilicate molecular sieve is taken as a matrix, and the yttrium-regulated and modified bentonite agent and the hydroxyapatite regulator are added and are mutually blended and jointly synergized, so that the compression resistance, the adsorbability and the abrasion resistance of the product are enhanced. 本发明公开了一种高吸附高抗压分子筛，高吸附高抗压分子筛包括硅铝酸盐分子筛、钇调节改性的膨润土剂、羟基磷灰石调节剂；其中硅铝酸盐分子筛、钇调节改性的膨润土剂、羟基磷灰石调节剂的物质质量比为（5-7）:（2-4）:1。本发明高吸附高抗压分子筛以硅铝酸盐分子筛为基体，通过加入
