Indonesia has the potential to develop biomass, such as MSW and wood pellets, as a source of energy. Syngas from biomass gasification can be used as fuel for dual-fuel diesel engines in order to transition energy. We investigated the gasification of MSW and wood pellets using a downdraft reactor with a capacity of 130-144 kg in order to determine the properties of the produced syngas for use in dual-fuel syngas diesel engines. Four days are dedicated to the process of preheating biomass with sunlight. The experiment was designed with an equivalent ratio of 0.22 and an oxidation zone temperature between 700 and 900 degrees Celsius. According to the experimental results, the average lower heating value of syngas produced by the air gasification of MSW biomass was 5.85 MJ/Nm 3 , the cold gas efficiency was 56.6%, and the carbon conversion efficiency was 94.77%. The average lower heating value from wood pellet biomass air gasification was 5.95 MJ/Nm 3 , the cold gas efficiency was 67.7%, and the carbon conversion efficiency was 94.28%. Solar heating of bio-mass has been shown to increase the calorific value of biomass gasification to syngas.

| Additional Information: | Preheating in the sun for four days can reduce the oxygen, hydrogen, moisture, and volatile matter content, increase the molar and fixed carbon contents, and raise the HHV value of the feedstock. The gasification process utilises a downdraft reactor with a biomass capacity of 135–144 kg and an air rate of 180–220 L/min at an equivalent ratio of 0.22 at temperatures ranging from 700 to 900 °C. The gasification process with MSW biomass yielded gas concentrations of 25.76% CO, 12.16% CO2, 3.66% CH4, and 11.98% H2 at a feedstock mass rate of 11.67 kg/h. Syngas had an LHV of 5.85 MJ/Nm3, a cold gas efficiency of 56.5%, and a carbon conversion efficiency of 94.77%. The gasification process using biomass wood pellets with a feedstock mass rate of 12.73 kg/h resulted in gas concentrations of 22.96% CO, 17.42% CO2, 3.74% CH4, and 15.91% H2. Syngas had an LHV of 5.95 MJ/Nm3, a cold gas efficiency of 67.90%, and a carbon conversion efficiency of 94.27%. According to the findings of this study, using a downdraft reactor for gasification is sufficient to convert biomass into syngas. The method of solar preheating has been shown to increase the calorific value of feedstock and gas yield. The calorific value of yield gas indicates that it could be used as fuel in dual-fuel diesel engines. |
