| description | A method for synthesizing even-grained ZSM-5 molecular sieves belongs to the technical field of catalyst preparation. The method comprises the steps of: firstly, preparing seed crystal mixed solution by a coprecipitation method: controlling the PH value of the precipitate to the range of 8-11 during coprecipitation, grinding the precipitate to certain fineness by using grinding equipment after precipitation, and then obtaining the seed crystal mixed solution through crystallization; and preparing the ZSM-5 molecular sieves: firstly preparing the precipitate mixture by the coprecipitation method, adding the seed crystal mixed solution in a certain proportion, and obtaining the even-grained ZSM-5 molecular sieves through crystallization, filtering, washing and calcination. The method is capable of preparing the ZSM-5 molecular sieves of special granularity to meet the catalytic reaction requirements according to different reaction requirements. |
