以亚麻籽（Linum usitatissimum L.）以特别确定热解温度、加热速率、粒度和吹扫气体流速对热解产物产率及其组成的影响。最高出油率为57.7wt.%在550°C的最终热解温度、0.6 mm <dp<1.8 mm的粒度范围、300°Cmin-1的加热速率和100 cm 3 min-1（N2）的吹扫气体流速下，在良好吹扫的连续加热的固定床反应器中获得。热解产物的特征在于元素分析和各种色谱和光谱技术。通过色谱和光谱分析，确定了该油的热值为38.45MJ/kg，经验式为CH 1.64O 0.11N 0.03，可作为可再生燃料和化工原料。
Fixed-bed fast pyrolysis experiments have been conducted on a sample of linseed (Linum usitatissimum L.) to determine particularly the effect of pyrolysis temperature, heating rate, particle size and sweep gas flow rate on the pyrolysis product yields and their compositions. The maximum oil yield of 57.7wt.% was obtained at a final pyrolysis temperature of 550°C, particle size range 0.6 mm <dp<1.8 mm, with a heating rate of 300°Cmin−1and sweep gas flow rate of 100cm3min−1(N2) in a well-swept resistively heated fixed-bed reactor. The pyrolysis products were characterised by elemental analysis and various chromatographic and spectroscopic techniques. Chromatographic and spectroscopic studies on oil showed that it can be used as a renewable fuel and chemical feedstock, with a calorific value of 38.45MJ/kg and empirical formula of CH1.64O0.11N0.03.
