This article reports experimental results of rapid or fast pyrolysis of rice straw (RS) and rice husk (RH) in a fluidised-bed reactor unit incorporated with a hot vapour filter. The objective of this research was to investigate the effects of pyrolysis temperatures and the use of glass wool hot vapour filtration on pyrolysis products. The results showed that the optimum pyrolysis temperatures for RS and RH were 405 and 452 °C, which gave maximum bio-oil yields of 54.1 and 57.1 wt.% on dry biomass basis, respectively. The use of the hot filter led to a reduction of 4-7 wt.% bio-oil yield. Nevertheless, the glass wool hot filtered bio-oils appeared to have better quality in terms of initial viscosity, solids content and ash content than the non-filtered ones.
本文报道了在流化床反应器单元中，通过快速或快速热解稻秆（RS）和稻壳（RH），并结合热蒸汽过滤器的实验结果。本研究的目的是研究热解温度和使用玻璃纤维棉热蒸汽过滤对热解产物的影响。结果表明，RS 和 RH 的最佳热解温度分别为 405°C 和 452°C，在此温度下，以干生物质为基准，生物油的最大产率分别为 54.1%和 57.1%。使用热过滤器会导致生物油产率降低 4-7%。然而，与未经过滤的生物油相比，玻璃纤维棉过滤后的生物油在初始粘度、固体含量和灰分含量方面表现出更好的质量。
