The results showed that the use of silicon carbide gave rise to the highest final temperature of 1130 C, resulting in the highest yield of gas fraction (up to 63.2 wt.%). The low heating rate (200°C/min) which was attributed to the addition of residue char promoted condensation reactions and resulted in an increase in solid yield.
