SUMMARY:

Mineral coal is a solid fossil fuel that, in the burning process, generates large volumes of waste. As it is a waste that contains heavy metals, its disposal in inappropriate places causes great environmental impacts. In order to minimize waste management problems, use this material in the zeolite reproduction process, which are the porous crystalline materials based on aluminosilicates. The residue used as a study was supplied by SATC Criciúma - SC and presents its chemical composition 24.09% Al2O3 and 54.25% SiO2. Studies of the use of coal ash with the objective of obtaining ATL were carried out, both by hydrothermal and alkaline fusion, and the combination of two methods, varying as: crystallization time, Na / T ratio, ultrasonification, gel agitation temperature and temperature alkaline melting process of the residue. The results were characterized by X-ray diffraction techniques (XRD) and scanning electron microscopy (SEM-FEG).
