摘要
(CN104556098B) 本​发明​涉及​一种​大​孔径​一维​管状​沸石​及其​制备​方法,所​述​一维​管状​沸石​为​纳米​一维​中​空管​结构,其​内径​为​70-90nm,管壁​厚度​为​15-22nm,管​长​0.65-1​μ​m。管状​沸石​制备​方法​步骤​如下:1)制备​纯化​埃洛​石;2)制备​大​孔径​一维​管状​沸石:在​常温​常压​条件下,将​纯化​埃洛​石​研磨​至​粒径≤200​目​后​加入​氢氧化钠​溶液​中,混合​均匀​后置​于​水​热​反应​釜​中,于​100-110℃条件​下水​热​反应​20-24h,然后​对​产物​进行​后处理​得到​大​孔径​一维​管状​沸石。本​发明​方法​步骤​简单,反应​条件​温和,生产​周期​短,工序​简单,成本​低,次生​污染​少,适合​规模化​生产。

(CN104556098B) 1. A large pore zeolite one-dimensional tubular, characterized in, one-dimensional nano-zeolite is a one-dimensional tubular structure hollow tube, an inner diameter of 70-90 nm, a wall thickness of 15-22 nm, length of the tube 0.65-1 m.  2. A large pore zeolite is prepared tubular one-dimensional, characterized in the following steps: 1) preparing a purified halioysite: will halioysite Mine distilled water was added, followed by sodium hexametaphosphate, and adjusting the pH value of 8-9, and then subjected to ultrasonic dispersion and at 50-60 Ć under stirring for 10-12h, obtained halioysite suspension, the suspension was centrifuged supernatant take standing, drying, to obtain a purified halioysite; 2) preparing a large pore size zeolite one-dimensional tubular: at normal temperature under normal atmospheric conditions, the step 1) the resulting purified  200 mesh sodium hydroxide solution was added after milling to a particle size halioysite within, mixed with the mixture placed in a hydrothermal kettle, for 100-110 Ć under hydrothermal reaction conditions 20-24h, and the product was worked up to give large pore size zeolite one-dimensional tubular; Wherein step 1) one-dimensional tubular structure having a nano-Mine halioysite, an inner diameter of tube 10-30 nm, the tube having a length of 0.5-3 m; Step 2) sodium hydroxide solution at a concentration of 2% by mass, the mass to volume ratio of 1g: 38 with sodium hydroxide solution purified halioysite-40 ml.
