| titleOfInvention | Method for synthesizing nano GaZSM-5 silicon gallate molecular sieve by dry glue conversion method |
| abstract | The invention discloses a method for synthesizing a nano GaZSM-5 silicogallate molecular sieve by a dry glue conversion method, and aims to solve the problems of long crystallization time, environmental pollution caused by waste liquid discharge and large molecular sieve particle size in the conventional hydrothermal synthesis method of the ZSM-5 molecular sieve. The synthesis method comprises the following steps: firstly, weighing raw materials; secondly, adding tetrapropyl ammonium hydroxide aqueous solution and deionized water into the gallium sesquioxide, and heating and reacting to prepare reaction solution; thirdly, dropwise adding ethyl orthosilicate into the reaction solution to prepare mixed gel; fourthly, stirring and mixing the gel at the rotating speed of 300-500 r/min; and fifthly, adding the dry glue into a closed reaction kettle, carrying out solid phase crystallization reaction at 160-185 ℃, and drying to obtain the nano GaZSM-5 silicate gallate molecular sieve. The dry gel conversion method adopted by the invention has short crystallization time and no waste water discharge, and Ga atoms successfully enter a molecular sieve framework, and the size of a single crystal grain is about 20-30 nm. |
