The zeolites were ball milled at different speeds (500, 1000, 1500, and 2000 rpm) for varying durations (5–90 min). The temperature during BM was maintained below 50 °C through a Huber Unichiller (Huber, Germany). Further, to prevent any possible overheating, the machine was paused for 3 min after every 1 min of running.

The wet ball milling of a commercial zeolite HY sample having a Si/Al ratio of 2.6 was carried out in the Szegvari Attritor System. The zeolite samples were ground for different periods of time varying between 1 and 14 h. Two different milling speeds (400 and 600 rpm) and two different ball sizes (2 and 3 mm) were used in the experiments.
