| titleOfInvention | HYDROTHERMIC METHOD FOR DIRECT SYNTHESIS OF ZEOLITES FROM FLYING ASH. |
| abstract | The present invention describes a hydrothermal method for promoting direct zeolitization of fly ash obtained in the thermoelectric industry as by-products of the combustion of mineral coal. Fly ash with a total content of 80% Si02 + A1203, low content of thermodynamically stable crystalline species such as quartz, mulite, calcite and high content of amorphous material (79 5%), allow the ash to be especially reactive against a hydroxide of an alkali metal and / or alkaline earth metal, such that it is possible to carry out its zeolitization by the method described in the present invention. The method of the invention comprises reacting fly ash to hydrothermal conditions with a metal hydroxide in a certain proportion; The reactant mixture is directly subjected to a hydrothermal process with or without stirring at a temperature of up to 175 ° C and for a time of up to 24 hrs. The zeolites thus obtained are washed with deionized water, dried and packed in a hermetically sealed container for Conservation By the method of the invention, for example, analcime zeolites and zeolite W are obtained, both as single crystalline species, as well as zeolite P and ABW in admixture with an amorphous phase. |
