OVIEDO VILLAMIZAR, JENNY ANDREA; HENAO MARTINEZ, JOSE ANTONIO  e  RIOS REYES, CARLOS ALBERTO. A COMPARATIVE STUDY ON CONVERSION OF INDUSTRIAL COAL BY-PRODUCTS IN LOW SIO₂ ZEOLITE OF FAUJASITE TYPE. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.176, pp.105-114. ISSN 0012-7353.

Colombian industrial coal by-products were evaluated as raw materials in laboratory-scale synthesis of faujasite-type low-SiO₂ zeolite of using an alkaline fusion step followed by hydrothermal treatment under various experimental conditions. By fusion with NaOH followed by hydrothermal reaction, coal by-products were converted into faujasite-type zeolite. The process of faujasite formation is discussed.

Palavras-chave : coal by-products; synthesis; zeolitic materials; hydrothermal; fusion.
