NANOZEOLITES AND PROCESS FOR PREPARATION THEREOF

摘要

The invention generally relates to nanozeolites and process for their manufacture. In one aspect of the invention, there is provided a process for preparing nanozeolites comprising: i) providing an aqueous zeolite gel solution containing zeolite seeds; ii) contacting an organosilane in an organic solvent with the zeolite gel solution of step i) to produced organosilane-functionalized zeolite seeds; iii) treating the organosilane-functionalized zeolite seeds of step ii) to produce nanozeolite crystals; and iv) isolating the nanozeolite crystals from step iii). In a further aspect, there is provided a nanozeolite having a small crystal size and high specific and hydrophobic external surface areas.
