Zusammenfassung:	Provided are hollow spherical zeolite IM-5 and a preparation method therefor. A cation quaternary ammonium salt surfactant having a long carbon chain is added to an zeolite IM-5 preparation system, where the molar ratio of a template agent/the surfactant is between approximately 0.3 and approximately 4.5, and hollow spherical zeolite IM-5 is generated via the micelle effect of the surfactant. The structure facilitates material mass transfer of a reaction process. L'invention concerne une zéolite sphérique creuse IM-5 et un procédé de préparation de celle-ci. Un agent tensio-actif sel d'ammonium quaternaire cationique ayant une chaîne carbonée longue est ajouté à un système de préparation de zéolite IM-5, le rapport molaire d'un agent de matrice/l'agent tensio-actif se situant entre approximativement 0,3 et approximativement 4,5, et la zéolite sphérique creuse IM-5 est générée par l'effet micelle de l'agent tensio-actif. La structure facilite un transfert de masse de matière d'un procédé de réaction.
