Study on the Thermal Simulation for Hydrocarbon Generating by Unicellular Algae

以单细胞海藻为材料进行热模拟生烃试验 ,对其不同温度级别下作了气体成分分析、族组份分析、热解色谱测试分析 .从常温到 2 50℃ ,单细胞海藻中有机质还未成熟 ,但具有很强的生烃能力 ,30 0～ 4 0 0℃达到成熟阶段 ,是其热模拟生烃的高峰期 ,4 0 0～ 50 0℃时单细胞海藻中的有机质已经达到过成熟阶段 ,为产气为主 .热模拟试验结果表明单细胞海藻是良好的生烃原始母质 。

The thermal simulation experiments for generating hydrocarbon by unicellular algae are carried out and several analysis methods, such as Gas Analysis, Components Analysis and Thermal Simulation Chromatogram Analysis are applied. The results show that unicellular algae are good kinds of sources for generating hydrocarbon. The organic matters of unicellular algae are not matured from normal temperature to 300 ℃, but their potential ability of generating hydrocarbon are strong; the organic matters of unicellular algae are matured from 300 ℃ to 400 ℃, and their ability of generating hydrocarbon reach maximum; The organic matters of unicellular algae are super matured from 400 ℃ to 500 ℃, and their ability of generating hydrocarbon are declined. The thermal simulation examination has distinctly revealed the course of thermal evolution of organic matter and oil/gas generation.
