“…Meanwhile, when the SWP is gasified, the H2 is raised at 11%. This results supported that densification have the potential to facilitate the syngas formation (Aydin et al, 2019). The observed increase of CO2 in SW could be attributed that most of the CO is transformed to CO2 during the water-gas shift reactions within the gasification process.…”

“…performing similarly like coal in terms of physical, grinding, chemical, and storage properties with the higher volatiles content. Additionally, Aydin et al, (2019) performed the gasification between pine cone particle and wood pellet in a fixed bed downdraft gasifier. The results revealed that the cold gas efficiency of the wood pellet possesses 80% higher than pine cone particle, 60% with the optimal gasification temperature interval for the wood pellet is much lower than the pine cone particle.…”

In this work, a comparative analysis of the gasification process of sawdust (SW) and sawdust pellet (SWP) utilizing a downdraft gasifier was performed. The gasification was conducted in a research-scale fixed-bed gasifier applying air as an oxidizing agent. The comparison between the raw (sawdust, SW) and treated biomass (sawdust pellet, SWP) was investigated for the syngas composition and gasification performance at the fixed condition of gasification temperature at 750 °C and equivalence ratio of 0.25. The gasification performance was tabulated in the form of heating value of the syngas (HHVsyngas), gasification efficiency (ηGE) and carbon conversion efficiency (ηCCE). It was found out that SWP produced the highest H2 and the lowest CO2. Furthermore, SWP also present the better gasification performance than SW. SWP achieved the high HHVsyngas, ηGE, and ηCCE at 4.2152 MJ/Nm3, 24% and 37%, respectively.

“…Since the rise on hydrogen was greater than that of carbon monoxide, the ratio of H 2 /CO increased by degrees. If the gasification temperature was relatively low, CO 2 tended to be generated through water-gas shift reaction and methanation reaction (exothermic) [26]. For fine coal gasification in this study, the H 2 /CO ratio was 1.3-2.23.…”

Fine coal waste from the coal mining process has not been used as clean energy even though the amount is very abundant in the world. The conversion of fine coal to syngas is a new way to increase the value of fine coal. Syngas composition, gas ratio, gasification efficiency, and heating value of syngas have been determined under various conditions of temperature (550-750 °C) and bentonite catalyst ratio (0-0.25). The results indicate that fine coal is the suitable raw material for the gasification process. At the highest temperature (750 °C), the gas composition consists of 42.6 vol% H2, 19.1vol% CO, 19.5 vol% CH4, and 7.9vol% CO2. The best performance was achieved when the catalyst/feed ratio is 0.25 with the gas composition of 54.3vol% H2, 26.2vol% CO, 23.8 vol% CH4, and 3.5vol% CO2, heating value and gasification efficiency were 19.72 MJ/Nm3 and 72.27% at 750 °C.

Gasification is a thermo-chemical process used to convert biomass fuelsinto a fuel gas. Biomass gasification is considered amongst the best methods to enhance biomass-based energy production’s efficiency as it allows common biomass utilization.It has become more important as a mean of converting low energy-density such as biomass feeds or into a transportable high value gas for heat and power generation, chemicals and fuels. Operating conditions are affecting the gasification reactions. the review identified that in high-temperature gasification, endothermic reactions the secondary cracking and reforming of heavy hydrocarbons are favored and hence enhances the whole process’s efficiency. Finally, catalysts are vital for the biomass gasification process, and it is important to select the appropriate ones taking into consideration possible setbacks discussed above and will be explored further in this study.
