Optimization Of Acid Activation Conditions For Mabisian Clay And Its Application In Pyrolysis Of Mixed Plastic Waste

Abstract
In this study, acid modification of Myanmar Natural clay was optimized and conducted the catalytic pyrolysis of mixed plastic wastes in the fixed bed reactor. Mabisian clay was activated using sulphuric acid at various acid concentrations (2-10M), reaction temperature (60-100�C) and contact times (1-3 hr). In this process, response surface methodology (RSM) based on Box-Behnken experimental design was applied. RSM results showed close agreement between experimental and predicted value. The physicochemical properties of modified samples were characterized by X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR) andscanning electron microscope (SEM). The chemical treatment increased the Si/Al ratio from 1.405 to 3.102 and decreased the size of clay structure. Product fuel was analyzed by using Gas Chromatography and Mass Spectrometer (GC/MS) and GC/MS result showed product fuel consist of gasoline 58.51%, naphtha (74.9%), kerosene (25.8%), diesel oil (25.8%), grease (5.28%), fuel oil (1.97%) and greases and wax (0.28%).
