A Pyrolytic Study: The Effects of Heating Rates and Sweeping Gas Flow Rates on Temperatures

Abstract

Fixed bed pyrolysis experiments have been conducted on waste cotton scrap materials for various process parameters. The effects of pyrolysis temperatures, well-swept gas atmospheres (N2), and heating rates on the pyrolysis process have been investigated. For this purpose, low (700 cm3/min) and high (3,900 cm3/min) N2 flow rates, low (5°C/min) and high (10°C/min) heating rates were performed for the reaction temperatures of 250°C, 350°C, 500°C, 600°C, 700°C, 800°C, and 900°C. The maximum liquid yield (34.93%) was obtained in 3,900 cm3/min N2 flow rates at 10°C/min heating rate at 500°C. The maximum gas yield (60.92%) was obtained in 3,900 cm3/min N2 flow rates at 5°C/min heating rate at 900°C.
