The pyrolysis characteristic of furniture processing residue (FPR), which was analyzed by thermogravimetric analysis (TGA) under nitrogen atmosphere, mainly decomposed between 230 °C and 500 °C. The FPR was submitted to fast pyrolysis in a bubbling fluidized-bed reactor (BFR) for converting into bio-oil, bio-char. The product distribution and characteristics of bio-oil depend on the operating conditions (temperature, fluidizing flow rate, particle size of sample). The bio-oil yield showed the highest value (50.68 wt%) at the pyrolysis temperature of 450 °C with a biomass particle size of 1.0 mm and a fluidization velocity of 2.0×Umf. The bio-oil had high selectivity for dioctyl phthalate, levoglucosan, and phenolic derivatives. The carbon number proportions in bio-oils of FPR were 32.74 wt% for C5–C11 fraction, 47.60 wt% for C12–C18 fraction and 19.38 wt% of C25–C38 fraction, respectively. The gas product included CO, CO2, H2, and hydrocarbons (C1–C4), and the selectivity of CO2 was the highest. The high heating value (HHV) of gas products was between 4.60 and 12.90 MJ/m3. The bio-char shows high HHV (23.87 MJ/kg) and high C content (62.47 wt%) that can be applied as a solid fuel.

家具加工残渣的快速热解产生生物油

家具加工残渣(FPR)的热解特性是在氮气氛下通过热重分析(TGA)进行分析的,主要在230°C至500°C之间分解。将FPR在鼓泡的流化床反应器(BFR)中进行快速热解,以转化为生物油,生物炭。生物油的产品分布和特性取决于操作条件(温度,流化流速,样品的粒径)。在450°C的热解温度下,生物油收率最高(50.68 wt%),生物质粒径为1.0 mm,流化速度为2.0×U mf。该生物油对邻苯二甲酸二辛酯,左旋葡聚糖和酚类衍生物具有高选择性。对于C 5,FPR生物油中的碳数比例为32.74 wt%–C 11馏分,C 12 –C 18馏分的47.60 wt%和C 25 –C 38馏分的19.38 wt%。气体产物包括CO,CO 2,H 2和碳氢化合物(C 1 -C 4),CO 2的选择性最高。气体产品的高热值(HHV)在4.60和12.90 MJ / m 3之间。该生物炭显示出高HHV(23.87 MJ / kg)和高C含量(62.47 wt%),可以用作固体燃料。
