Synthesis of Dense Y-zeolite Bulks with Large Surface Area Using a Hydrothermal Hotpressing (HHP) Process

Highly dense and large bulk Y-zeolites (1.5 mm in thickness and 20 mm in diameter) with a significantly large surface area over 700 m^2/g were obtained by a short-term hydrothermal hot-pressing (HHP) treatment at 423 K for 2 h, comparable with the Y-zeolite powder.
