Abstract
A shaped zeolite-containing body, e.g., zeolite-containing monoliths, having high compressive strength is prepared from a particular class of siloxane-based binders in combination with zeolite, plasticizing agent, and methylcellulose. It has been discovered that when using the particular class of siloxane binder with the aforementioned components, the body formed therefrom can be processed and calcined at temperatures below 300.degree. C., thereby reducing costs typically seen with other processes for preparing shaped materials containing zeolite. The shaped bodies of this invention have been shown to have compressive strengths of at least 20 N/mm.sup.2 or more.
