| 发明名称 | Hollow spherical zeolite IM-5 and preparation method therefor | ||
| 摘要 | The present invention provides a hollow IM-5 molecular sieve sphere and the preparation process thereof. The process according to the present invention adds a relatively great amount of the surfactant of a cationic quaternary ammonium salt in the IM-5 molecular sieve system, to form a hollow IM-5 molecular sieve sphere via the micelle action by the surfactant, which structure benefits the mass transfer of the reaction process. | ||
