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.

由生物质废物和垃圾衍生燃料炭的混合物制成的颗粒气化

摘要 垃圾衍生燃料 (RDF) 在 300 °C 下碳化 30 分钟，所得 RDF 炭用作生物质颗粒的添加剂。制备并表征了含有 0、5 和 10% RDF 炭的松木废料颗粒。RDF 炭的掺入导致球团的固定碳和灰分含量增加。颗粒在 1 kg/h 鼓泡流化床气化炉中在不同温度（800 和 850 °C）和当量比（0.25 和 0.30）下进行气化。发生炉气产量从 1.5 到 2.5 m3/kg 不等，ER 为 0.25 时更高。碳转化率和冷气效率分别在 60.4% - 96.1% 和 42.3%-73.7% 之间。CO、CO2、H2 和 CH4 的浓度达到了 13.3-17.4 vol% 干燥 CO2、13.1-14.7 vol% 干燥 CO2、4.9-11.1 vol% 干燥 H2 和 3.5-4。CH4 为 4 vol% 干。气化过程中产生的焦油主要包含芳烃和苯酚，显示出重多环芳烃浓度随着 RDF 炭掺入量的增加而增加。RDF 炭可用作中等掺入比的气化添加剂。
