Abstract
A method for synthesizing a supported molecular sieve membrane by microwaves includes the steps of aging, heating and synthesizing. The aging step is to make a support in contact with a synthetic liquid at 25° C. to 70° C. for 10 hours to 24 hours; the heating step is to raise a temperature of an aged system from an aging temperature to a synthesis temperature within 1 minute to 10 minutes; and the synthesizing step is to synthesize at 80° C. to 120° C. for 2 minutes to 15 minutes. The steps of heating and synthesizing are powered by microwaves.
Claims3
A method for synthesizing a supported type-A molecular sieve membrane by microwaves, comprising the steps of aging, heating and synthesizing, wherein:
- the step of aging comprises contacting a support with a synthetic liquid at an aging temperature 25° C. to 50° C. for 16 hours to 20 hours to obtain an aged system;
- the step of heating comprises raising a temperature of the aged system from the aging temperature to a synthesis temperature within 3 minutes to 6 minutes under microwave heating;
- the step of synthesizing comprising synthesizing the aged system at the synthesis temperature of 80° C. to 120° C. for 6 minutes to 10 minutes under microwave heating, and
- the synthetic liquid contains 2.64 mol/L of Na2O, 0.053 mol/L of Al2O3, and 0.263 mol/L of SiO2.
