BIOMASS-BRIQUETTES FUEL FROM LOCAL WISDOM FOR PRODUCER GAS PRODUCTION

บทคัดย่อ

This study investigates the preparation of biomass-briquettes from local wisdom for producer gas production. The biomass-briquettes fuel was prepared from agricultural biomass residues such as black rice husk, corn cop, sawdust, starch, and cow dung. The biomass-briquettes fuel of different formulas has the percentage of moisture content in the range of 2-4%, volatile content in the range of 65-69%, ash content in the range of 11-19%, and carbon content in the range of 11-18%. For the carbonized biomass-briquettes fuel of different formulas, they have moisture content in the range of 0.1-0.5%, volatile content in the range of 54-60%, ash content in the range 16-24%, and carbon content in the range of 19-30%. The high heating value properties of the biomass-briquettes fuel and the carbonized biomass-briquettes fuel were in the range of 16-18 MJ kg^-1. Both the biomass-briquettes fuel and the carbonized biomass-briquettes fuel produced the most CO gas, followed by H₂, CO₂ and CH₄, respectively. The producer gas which was produced by using the carbonized biomass-briquettes fuel has a slightly higher amount of CO, H₂, and CO₂, but with less CH₄ than using the biomass-briquettes fuel.
