PRELIMINARY STUDY OF CO-GASIFICATION OF DIFFERENT LIGNOCELLULOSIC BIOMASS IN BENCH SCALE REACTOR

Utilisation of biomass energy for power generation is a cheapest and environmental
friendly way via gasification technology. However, challenge with biomass
gasification is shortage of feedstock for continuous gasification process which
consequently interruption in power generation. Mixing ofdifferent biomass materials
improved the physical or morphological behaviour of inferior biomass that reduces
the operational instability ofprocess. Co-gasification of different biomass materials
would enable flexible utilisation of solid feedstock in order to obtained uniform gas
composition for power generation applications. The current research focuses on the
co-gasification of different lignocellulosic biomass materials with different blending
ratios for the quality of syngas and performance of the process. Furthermore, the
temperature profile and syngas flare obtained from different blending ratios of
feedstock were studied. Characterization of biomass materials (wood, OPF and
coconut shell) mainly consists ofultimate analysis, proximate analysis, heating value
and elemental analysis were investigated prior to experiments. The co-gasification
study was carried out in a batch feed downdraft gasifier. The syngas composition
(CO, H2, CH4 and C02) from each experiment was analyzed using Emerson X-Stream
online gas analyzer.
