The results obtained confirmed that the increasing temperature in the pyrolysis zone of the gasifier causes the syngas production to be enhanced up to a maximum fraction of 33.12 vol% and 16.57 vol% for H2 and CO respectively. This is due to enhance the hydro-cracking of heavy hydrocarbons and further conversion through reforming reactions that subsequently contribute to the syngas production with a maximum syngas yield of 382.4 g/kg feedstock
