Abstract

Refuse derived fuel (RDF) was carbonized at 300 °C for 30 min and the resulting RDF char was used as additive for biomass pellets. Pine waste pellets with 0, 5 and 10% incorporation of RDF char were prepared and characterized. RDF char incorporation caused an increase in fixed carbon and ash contents of the pellets. The pellets were subjected to gasification in a 1 kg/h bubbling-fluidized-bed gasifier at different temperatures (800 and 850 °C) and equivalence ratios (0.25 and 0.30). The producer gas yield varied from 1.5 to 2.5 m³/kg and was higher for an ER of 0.25. Carbon conversion and cold gas efficiency presented values between 60.4% - 96.1% and 42.3%-73.7%, respectively. Concentrations of CO, CO₂, H₂ and CH₄ reached values between 13.3-17.4 vol% dry for CO, 13.1-14.7 vol% dry for CO₂, 4.9-11.1 vol% dry for H₂ and 3.5-4.4 vol% dry for CH₄. Tars produced during gasification contained mainly aromatic hydrocarbons and phenols, showing an increase in heavy PAHs concentration with higher RDF char incorporation. The RDF char can be used as a gasification additive at moderate incorporation ratios.
