ABSTRACT:
Forms of zeolite Omega synthesized by hydrothermal crystallization from reaction systems containing alkali metal cations and organic templating agents, modified by calcination in air, ion-exchange, steam calcination and treatment with a low-pH aqueous ammonium ion solution, are significantly improved with respect to surface area, catalytic activity and adsorption capacities for large molecular species.
