Patent ID: 7132095

Claim:
A method for manufacturing zeolite from ashes resulting from the incineration of combustible waste (hereinafter “ashes”), with said method comprising: (1) a step for (a) introducing the ashes into a first tank (of two tanks) so as to form a liquid that contains, as a solvent, either an alkaline aqueous solution or water, air and electrolytic water, and (b) continuously reintroducing that liquid into a first (of two) substance-separating/recovering device so as to make that liquid harmless; and (2) a step for (c) introducing into a second tank the clear liquid that has been separated and recovered in said first substance-separating/recovering device and then returned into the first tank, so as to convert that clear liquid into a heat-treated liquid that contains an alkaline aqueous solution as a solvent, and (d) continuously reintroducing said heat-treated liquid into a second substance-separating/recovering device so as to crystallize that heat-treated liquid into zeolite that contains tecto-alumino-silicate.
