- Abstract
This research work completed the study of obtaining zeolite by hydrothermal method using the ash of Erdenet Thermal Power Plant. According to the results of the study, the ratio of macroelements of ash in the ash pond of Erdenet Thermal Power Plant is less than 1, so it belongs to acid ash. Also, based on the content of oxides, it was determined that the ash of Erdenet Thermal Power Plant is a siliceous type of ash due to the high content of silicon and aluminum oxides, and the low content of iron and calcium oxides. According to the results of the XRD analysis of natural zeolite, it contains Ca(Si7Al2)O186·H2O-86.94% and SiO2-13.06%. However, based on the results of XRD analysis of zeolite subjected to heat treatment, Ca(Si7Al2)O186·H2O - 47.3%, SiO2-27.48%, Al2Si2O8- 20.64% were formed. Depending on the results of the XRD analysis of the synthesized zeolite, Sodalite (Na4Cl(Al3Si3O12)-83.72% at 200°C. Optimal reaction conditions for extracting zeolite from ash by hydrothermal method Ash: NaOH ratio 1:6, reaction temperature 80℃, stirring speed 200 rpm, reaction time 3 hours, hydrothermal temperature 200℃, time 4 hours, zeolite yield 83.72% Na4Cl(Al3Si3O12) was determined.
