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.
