MCM-41 molecular sieve as well as synthesis method and application thereof

The invention relates to the field of solid waste resource utilization, and discloses a synthesis method of an MCM-41 molecular sieve, the MCM-41 molecular sieve prepared by the synthesis method and application of the MCM-41 molecular sieve. The synthesis method of the MCM-41 molecular sieve comprises the following steps: (1) under a microwave-assisted extraction condition, contacting coal gasification fly ash with an extracting agent, and then carrying out solid-liquid separation to obtain desiliconized ash and a first solution; (2) mixing the first solution, a surfactant and an optional pH regulator to obtain a second solution with the pH value of 9-12; (3) carrying out hydrothermal crystallization on the second solution; and (4) roasting a solid product obtained by the hydrothermal crystallization in the step (3). According to the method, resource utilization of solid waste is achieved, products with high additional value are obtained, and good economic benefits and social benefitsare achieved. 本发明涉及固体废物资源
