Abstract
Novel synthetic zeolite compositions of extremely small particle sizes that have increased loading capability, and process technology for producing such compositions are described. So far as is presently known, it has never been possible to form such compositions heretofore. The process technology involves, inter alia, contacting the zeolite cake formed in its production with a specified type of treating agent and then subjecting the treated zeolite to physical subdivision.
