Abstract
Disclosed is an abrasion-resistant granular zeolite formed from a mixture of a synthetic zeolite and a clay binder, said granular zeolite comprising a core composed of a synthetic zeolite clay binder mixture containing the synthetic zeolite at a content higher than the average synthetic zeolite content in the granular zeolite and a shell composed of a synthetic zeolite-clay binder mixture containing the clay binder at a content higher than the average clay binder content in the granular zeolite. This granular zeolite is excellent in both the zeolitic characteristics such as adsorbability and ion exchange capacity and the mechanical strength characteristics such as abrasion resistance and compression strength.
