Granular TNU-9 molecular sieve and preparation method thereof

The invention relates to a method for preparing a granular TNU-9 molecular sieve, which comprises the following steps: a, carrying out contact reaction on dichlorotetramethylene, N-methylpyrrolidine and a solvent in a molar ratio of 1: (1.85-2.85): (2-22) at 20-90 DEG C for 4-100 hours to obtain a first product; and b, mixing the first product, an inorganic alkali source, an aluminum source, a silicon source and water to obtain a mixed material, carrying out hydrothermal crystallization treatment on the mixed material, and recovering a solid product. According to the present invention, the granular TNU-9 molecular sieve with the large particle size is synthesized at the low cost, the tedious processes of high-cost separation, purification and the like necessary for the conventional synthesis of the TNU-9 molecular sieve template agent are omitted, and a large amount of time consumption, energy consumption and material consumption are avoided. 本公开涉及一种制备颗粒状TNU-9分子筛的方法，该方法包括以下步骤：a、使摩尔比为1：(1.85～2.85)：(2～22)的二氯四亚甲
