“…Tar, described as a viscous black liquid formed during the pyrolysis process, resulted from the mixture of complex hydrocarbons [23]. CnHmOp (biomass) + Heat ⎯> CaHbOc (tar) + CxHyOz (gas) + H2O + char (13) In gasification using an updraft reactor, the tar production typically falls within the range of 5-20%, with the maximum tar production reaching 20% of the biomass raw material mass. The highest tar production in the gasification of coconut shells and MSW was observed at 850°C, amounting to 10.20 grams (20.4%).…”

Cogasification represents a thermochemical reaction employed to transform by combining biomass or fossil carbonaceous materials into combustible matters. Widely acknowledged as the most appealing approach among various combustible material to useful energy. This method offers significant potential for environmentally friendly energy production, boasting low carbon emissions. This study conducted gasification tests utilizing an updraft gasifier, incorporating parameters variable at 650°C to 850°C. The materials utilized consisted of a blend of Municipal-Solid-Waste (MSW) and coconut shells, maintaining a steam to biomass at 1.3. Optimum temperature at 750°C, the syngas revealed 41.30% mol CO, 20.90 mol% CO2 37.25 mol% H2, and 0.55 mol% CH4. Notably. The highest H2 gas production was achieved at this temperature. Furthermore, the net caloric value at this temperature, surpassed other variations, reaching 374.67 kJ/mol, accompanied by the generation of 11.38% of tar and 21.1% char.

The current hydrogen generation technologies, especially biomass gasification using fluidized bed reactors (FBRs), were rigorously reviewed. There are involute operational parameters in a fluidized bed gasifier that determine the anticipated outcomes for hydrogen production purposes. However, limited reviews are present that link these parametric conditions with the corresponding performances based on experimental data collection. Using the constructed artificial neural networks (ANNs) as the supervised machine learning algorithm for data training, the operational parameters from 52 literature reports were utilized to perform both the qualitative and quantitative assessments of the performance, such as the hydrogen yield (HY), hydrogen content (HC) and carbon conversion efficiency (CCE). Seven types of operational parameters, including the steam-to-biomass ratio (SBR), equivalent ratio (ER), temperature, particle size of the feedstock, residence time, lower heating value (LHV) and carbon content (CC), were closely investigated. Six binary parameters have been identified to be statistically significant to the performance parameters (hydrogen yield (HY)), hydrogen content (HC) and carbon conversion efficiency (CCE)) by analysis of variance (ANOVA). The optimal operational conditions derived from the machine leaning were recommended according to the needs of the outcomes. This review may provide helpful insights for researchers to comprehensively consider the operational conditions in order to achieve high hydrogen production using fluidized bed reactors during biomass gasification.
