Abstract. The objective of this paper is computational investigation of the carbon black production through the oxidative thermal decomposition of waste gases contain and without requiring a separation process. The chemical reaction model, which involves solid carbon, sulfur compounds and other precursor species for formation carbon black, based on an assumed Probability Density Function (PDF) is parameterized by the mean and variance of mixture fraction and β-PDF shape. The effects of feedstock mass flow rate and reactor temperature on carbon black, soot, , and formation are investigated. The results show that the major factor influencing and conversions is reactor temperature. The results reveal that at any temperature, conversion is less than that of CH4 especially at temperature below wherein H2S conversion is less than 5%.
