Figs. 2 and 3 represent the gas composition and product yield achieved by varying the gasification zone temperature in the range of 750–1100 C while ER, S/B ratio and pyrolysis zone temperature
were kept constant at 0.24, 0.64 and 500 C respectively. In this study the gasification efficiency was reflected by the carbon conversion which achieved up to a maximum of 84.1% and was calculated
by,
