description | Method of preparing iron-free zeolites from naturally-occurring materials which contain silicon, aluminium, and iron oxides to be found in nature in kaolin, clay, pumice and like forms by hydrothermally attacking the natural base materials, filtering the solid residue from the resulting solution, which contains all of the iron or compounds thereof; said solution, which constitutes the iron-free master liquor, is then subjected to a hydrothermal treatment at constant temperature for a determined time period, thereby iron-free zeolite is obtained which is filtered out. Also disclosed is a plant for implementing the method. |
