摘　　要：以蓝藻为研究对象,并以松木为参照,在流化床反应器中进行了热解液化制取生物油的试验研究,考察了温度对两种生物质原料热解产物的影响。研究表明,随着温度的升高,蓝藻和松木的产气率逐渐增加,产炭率逐渐减小,产油率先增加后减小,当温度为500℃时,达到最大值分别为50.4%和45.2%。采用气质联用(GCMS)测定两种生物质热解生物油的化学组成。结果表明:两种生物油的化学组分及相对含量存在一定的差异,但均属于相同的化学族类,其主要组成成分为含氮化合物、烃类、酮类、醇类、酸类、苯酚类等化合物。此外,通过元素分析可知,蓝藻生物油含氧量较松木低,有利于油品质的提高,使蓝藻热解液化制取生物油具有良好的发展前景。Experimental research on preparation of bin-oil by cyanobacteria pyrolysis liquefaction with reference to pine in a fluidized bed reactor. Investigate the effect of temperature on pyrolysis products of tow kinds of biomass. The results showed that the gas production rate of cyanobacteria and pine increased gradually with the temperature rised, while the charcoal yield decreased gradually and the bio-oil yield first increased then decreased. When pyrolysis temperature was up to 500 ℃ ,the maximum value of bin-oil yield rate by cyanobacteria and pine reached 50.4% and 45.2% （w/w） respectively, determine the chemical composition of bin-oil production using GC-MS, the resuits showed that there were some differences between chemical composition of two kinds of bin-oil and the relative content, but the major components were in the same chemical species, including nitrogen compounds, hydrocarbons, ketones, alcohols, acids, phenols ect. In addition, the bin-oil of cyanobacteria had lower oxygen and higher calorific value than pine by ultimate analysis, which was beneficial to improve the oil quality, so preparation of bin-oil by cyanobacteria pyrolysis liquefaction had a good development prospects.
