Abstract
Abstract Fixed bed pyrolysis experiments have been conducted on waste cotton scrap materials for converting into fuel form. The effect of temperature on the pyrolysis experiments has been investigated at the temperatures of 250°C, 350°C, 500°C, 600°C, 700°C, 800°C, and 900°C. The maximum liquid amount (30%)was obtained at 500°C with 700 cm3/min N2 sweep gas flow rate of 5°C/min heating rate. The pyrolytic liquid was characterized by elementel analysis and chromatographic technique. First, this liquid was fractionated into n-pentane soluble and insoluble compounds (asphaltenes). Pentane soluble was then solvent fractionated into n-pentane, toluene, and methanol subfractions by fractionated column chromatography. The chemical characterization had shown that the pyrolytic liquid obtained from cotton scrap materials was quite similar to petroleum fuels.
