| 摘 要： | 在Aspen Plus平台上构建生物质移动床热解多联产系统模型,通过对秸秆热解过程的模拟,研究了生物炭、生物油和生物燃气三态热解产物特性,以及热解温度对系统燃料投入、水耗和电耗的影响。结果表明,随热解温度升高,生物炭热值逐渐增大。生物油和生物燃气的产率分别在450℃和650℃附近达到最大值。当热解温度为450℃时,生物油重质组分主要由糖衍生类和脂肪酸类物质构成,而轻质组分主要包括醛类、醇类和水;当热解温度为650℃时,生物燃气则主要由CO2和CO构成。生产过程中,系统的燃料消耗和电耗均随着热解温度的升高而增大,冷却水消耗量则经历先减少后增加的过程,并在450℃附近达到最小值。 |

| Abstract: | With the model of biomass moving-bed pyrolytic polygeneration system based on Aspen Plus simulator, the products characteristics of bio-char, bio-oil and pyrolysis-gas were studied and the influence of pyrolysis temperature on the system consumption of fuel, cooling water, and electricity were investigated. Results showed that the heating value of bio-char rises as the pyrolysis temperature increases. The maximum products yields of bio-oil and syngas were obtained at 450oC and 650oC, respectively. When the pyrolysis temperature was 450oC, the heavy bio-oil mainly consists of sugar derived and fatty acid, while the major components of light bio-oil were aldehyde, alcohol and moisture. CO and CO2 were the main components in the syngas at 650oC. In addition, the consumption of fuel and electricity rises with the temperature increase, while the consumption of cooling water decreases firstly and then increases at 450oC. |
