Isomerization process using modified zeolite Omega

摘要

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. A catalyst comprising zeolite Omega is effective for isomerization of aromatics and aliphatics.
