Economic Beta molecular sieve membrane synthetic method

Abstract

The invention relates to an economic Beta molecular sieve membrane synthetic method. Through improvement of the current technologies, a casting solution during a crystallization process is cycled outside a synthesis kettle, reasonable arrangement of a valve can control a volume of the casting solution in a deposition kettle and the casting solution at a corresponding time segment, and based on guarantee of crystallization effect, the seed coating effect can be optimum.

Description

technical field

[0001] The invention relates to a method for preparing a membrane, in particular to a method for preparing an all-silicon Beta molecular sieve membrane. Background technique

[0002] Membrane separation technology is a new separation technology that emerged rapidly after the 1960s. It has the functions of separation, concentration, purification and refinement, as well as high efficiency, energy saving, environmental protection, molecular level filtration and simple filtration process, easy to control, etc. Features, which have been widely used in many fields at present, have produced huge economic and social benefits, and have become one of the most important means in today's separation science. As a kind of inorganic membrane, molecular sieve membrane has better thermal and chemical stability than organic membrane, and has great application potential in the fields of organic solvent / water separation and gas separation, while Beta molecular sieve membrane is ...
