Abstract
This invention relates to a novel zeolite which has the crystal structure of zeolite beta. The novel zeolite SN-beta has a unique infrared absorbance spectrum, shows enhanced activity for transalkylation of di-isopropyl-benzene and shows less deactivation for cumene synthesis. The zeolite beta is prepared by taking an as-synthesized zeolite beta, steam treating it and then ammonium ion treating it to give a zeolite SN-beta with enhanced catalytic properties.
