performed in a pilot-scale updraft gasifier. Gasification experiments were conducted
at atmospheric pressure using air as oxidizing agent. The effects of equivalence
ratio on temperature profile, gas composition and gas calorific value are studied.
The equivalence ratios employed in this study are 0.18, 0.22, 0.29, 0.35 and
0.4. The results showed that the amount of combustible gases which are H_{2},
CO and CH_{4} was found to be in the range of 16.79-33.9% of the total
produced gases and the average composition of the syngas at an optimum equivalence
ratio of 0.29 was found to be 20.10% CO, 10.41% CO_{2}, 1.20% CH_{4}
and 6.60% H_{2} with an average calorific value of 4.42 and 4.62 MJ
Nm^{-3} as Low Heating Value (LHV) and Higher Heating Value (HHV). While
the maximum molar ratios of H_{2}/CO and CO/CO_{2} was found
to be 0.3 and 2.51, respectively.]]>Mohammed, M.A.A., A. Salmiaton, W.A.K.G. Wan Azlina, M.S.M. Amran, A. Fakhrul-Razi and Y.H. Taufiq-Yap,2005Chew, T.L. and S. Bhatia,2008Ni, M., M.K.H. Leung, K.
