“…Sawdust, which is the abundant waste resources obtained from the wood industries, have been approved its potential on the syngas composition and gasification performance [3,4]. Gasification of coal also have been carried out on the several types of coal that concluded each different types of coal properties gave influence on the gasification performance [5]. Generally, biomass has low energy density and is widely spread properties resulted in an adverse effect in terms of collection and transport cost.…”

The paper is an experimental study of the gasification process of sawdust (SW), sawdust pellet (SWP) and sub-bituminous coal (SBCoal) by using downdraft gasifier. The gasification was undertaken in a lab-scale fixed-bed gasifier operating under air as an oxidizing agent. The comparison on the raw biomass, treated biomass and coal was assessed in term of the product gas and gasification performance at a fixed condition of gasification temperature of 750 °C and equivalence ratio of 0.25. The gasification performance was tabulated in the form of calorific value of the syngas (HHV syngas ), gasification efficiency (X CGE ) and carbon conversion efficiency (X C ). It was denoted that SWP produces the highest H 2 and the lowest CO 2 . Furthermore, SBCoal possesses the highest gasification performance among the three feedstocks. Besides, the influence of the temperature between SW, SWP and SBCoal was evaluated at the equivalence ratio of 0.25. The findings demonstrate that rising the temperature, H 2 and CO for SW, SWP and SBCoal are increase. The volume of the CO 2 is constant as the temperature increases. In contrast, the CH 4 decreases with increase in the gasification temperature. As the gasification temperature increases, HHV syngas and X CGE of SW and SWP are increasing; meanwhile, SBCoal shows the opposite results. Simultaneously with rising gasification temperature, the X C 's of the SW, SWP and SBCoal are increasing.

“…Energy demand is increasing worldwide due to increasing world population and standard of living 5 .Due to the continuous depletion of oil and natural gas the future demand of energy is coal dependent as coal is probably the most abundant fossil energy of the world. Various drawbacks such as lower efficiency and carbon dioxide emission can occur due to the conventional utilization of coal for power generation 5,6 . In order to overcome this, implementation of clean coal technologies, which include advanced gasification systems, as well as carbon capture storage and utilization techniques are used and many approaches are also designed in a way to reduce the carbon emission and mitigate the impact climate changes and are thus are discussed in detail.…”
