To produce high quality bio-oil from biomass using fast pyrolysis, rice husks were pyrolyzed in a 1-5 kg/h bench-scale fluidized-bed reactor. The effect of hot vapor filtration (HVF) was investigated to filter the solid particles and bio-char. The results showed that the total bio-oil yield decreased from 41.7% to 39.5% by weight and the bio-oil had a higher water content, higher pH, and lower alkali metal content when using HVF. One hundred and twelve different chemical compounds were detected by gas chromatography-mass spectrometry (GC-MS). The molecular weight of the chemical compounds from the condenser and the EP when the cyclone was coupled with HVF in the separation system decreased compared with those from the condenser and EP when only cyclone was used.
为了使用快速热解从生物质中生产高质量的生物油，在 1-5 公斤/小时的实验规模流化床反应器中对稻壳进行了热解。考察了热蒸汽过滤（HVF）对固体颗粒和生物炭进行过滤的效果。结果表明，当使用 HVF 时，总生物油产率从重量的 41.7%下降到 39.5%，并且生物油的含水量更高，pH 值更高，碱金属含量更低。通过气相色谱-质谱联用仪（GC-MS）检测到 112 种不同的化学化合物。与仅使用旋风分离器时相比，当旋风分离器与 HVF 耦合在分离系统中的冷凝器和 EP 中时，化学化合物的分子量从冷凝器和 EP 中降低。
