“…Jeong et al ( 2017 ) performed a modelling study on co-gasification of wood pellet and Douglas coal using computational fluid dynamics, and then, the findings were also verified and corroborated with the real data obtained from the operating gasification plant in Spain, thus indicating the reliable accuracy of the modelling results. Despite that the research on modelling studies of co-gasification is making good progress (Ali et al 2017 ; Hantoko et al 2018 ; Zhang et al 2020 ), huge research gap is awaiting to be filled by more studies performed with different combinations of feedstock and inclusion of underexplored material such as refuse-derived fuel.…”

Dwindling fossil fuels and improper waste management are major challenges in the context of increasing population and industrialization, calling for new waste-to-energy sources. For instance, refuse-derived fuels can be produced from transformation of municipal solid waste, which is forecasted to reach 2.6 billion metric tonnes in 2030. Gasification is a thermalinduced chemical reaction that produces gaseous fuel such as hydrogen and syngas. Here, we review refuse-derived fuel gasification with focus on practices in various countries, recent progress in gasification, gasification modelling and economic analysis. We found that some countries that replace coal by refuse-derived fuel reduce CO 2 emission by 40%, and decrease the amount municipal solid waste being sent to landfill by more than 50%. The production cost of energy via refuse-derived fuel gasification is estimated at 0.05 USD/kWh. Co-gasification by using two feedstocks appears more beneficial over conventional gasification in terms of minimum tar formation and improved process efficiency.

“…The heating value (HV) of CO, H 2 and CH 4 was considered 10.1, 120 and 50 MJ/kg, respectively, whereas the density of these gases was considered to be 1.25, 0.09 and 0.72 kg/m 3 , respectively. 27 Besides, the CGE is the ratio between output energy from the syngas to the feed coal's input energy. The following formula was used to calculate the CGE.…”

This study investigates the gasification behaviour of bituminous coal using different reactants of CO 2 , steam and a mixture of CO 2 and steam under entrained flow gasification conditions at temperatures of 1000 C and 1200 C with atmospheric pressure. The major gas constituents of the syngas were measured using online micro-GC with a model number Varian 490, whereas the minor pollutant gases were analysed using Kitagawa gas detection tubes. A maximum carbon conversion of 86% was achieved under steam gasification at a temperature of 1200 C compared to 74% from CO 2 gasification. The higher carbon conversion from steam gasification is due to the higher gasification reactivity than CO 2 gasification. At 1000 C, the lower heating value (LHV) from steam gasification was determined to be 60%, 70% and 80% higher than that of CO 2 gasification using the reactant concentrations of 10, 20 and 40 vol. %, respectively. Using a stoichiometric 50/50 ratio of CO 2 and steam, the yield of H 2 , CO and CH 4 were increased by 56%, 106% and 35% compared to that of pure CO 2 gasification. At 1000 C, the LHV under mixed reactant condition is close to the LHV from the pure steam gasification at 1200 C. In steam gasification, increasing the temperature by 200 C from 1000 C decreases the LHV by 17 and 10% using 10 and 20 vol.% steam. The higher heating value from steam gasification is due to the H 2 and CH 4 -rich syngas compared to CO-rich syngas in CO 2 gasification. The BET surface area of the solid char from steam gasification is about 17 and two times higher than that of CO 2 gasification at 1000 C and 1200 C, respectively.

“…The typical composition of hydrogen in producer gas varies from 5-25% depending upon the fuel's moisture content. After separation and purification, it can be utilized in a fuel cell, and the biomass gasification process can be considered as one of the prominent processes for biohydrogen production (Ali et al, 2017). There are mainly two techniques available for gasification of biomass, viz., fixed bed mode and fluidized bed mode (Bhave, 2001).…”

The transformation of biomass using steam gasification is a chemical route to facilitate changes in organic or residue supported carbonaceous substances addicted to carbon mono-oxide, hydrogen including carbon-dioxide , etc. However, to commercialize the method of steam gasification, the hurdles persist during the gasification as well as downstream processing. This article delivers a summary of the different approaches that are described in the previous studies to achieve H2 refinement and adaptation within the gasifier system. These include advanced aspects in the research and development of biomass gasification (alike advancements under the gasification operation). The upshot of diverse operating conditions like steam flow rate, operating temperature, moisture content, gasifier agents, residence time, biomass to air, steam to biomass, equivalence ratio, etc. towards the execution of biomass gasifier. This review accomplishes that the interdependence of several issues must be considered in point to optimise the producer gas.
