Preparation of HTLcs from Magnesium Desulfurization Residues and their Catalytic Performance in Degradation of Waste Polyester
Keyword(s):
To recycle the solid wastes, the hydrotalcite-like compounds (HTLcs) were prepared from the magnesia flue gas desulfurization residues (MFGDR). The HTLcs as prepared and the products from degradation of Poly (ethylene terephthalate) (PET) were characterized by thermogravimetric analysis (TG) , x-ray powder diffraction (XRD) , fourier transform infrared spectrometer (FTIR) and differential scanning calorimetry (DSC) methods. Effects of calcining temperature and alkaline of solution on the structure and performance of HTLcs were studied. The main product of alcoholysis of PET was bis-hydroxyethyl terephthalate (BHET). The catalyst shows a potential application in solid waste treatment and recycle.
