Abstract

Artificial zeolite (A.Z.) having a high cation exchange capacity (C.E.C) is formed by treating coal fly ash (fly ash), discharged from a coal-fueled power plant, with an alkali solution.<BR>This study was carried out to determine the chemical composition of fly ash suitable as a raw material for A.Z. and to establish the process conditions to form A.Z. having a high C.E.C. from fly ash.<BR>The results can be summarized as follows :<BR>(1) The C.E.C. of A.Z. depends on the non-crystalline Al₂O₃ content in flyash.<BR>(2) The C.E.C. of A.Z. and the non-crystalline Al₂O₃ content in fly ash increase as the content of Na₂O+K₂O and/or Al₂O₃ in the fly ash increase.<BR>(3) A.Z. with a the high C.E.C. is formed through the addition of a suitable Al resource in the process of treating fly ash with an alkali solution.
