摘　　要：对自然状态下产出的多细胞宏观底栖藻紫菜(porphyra yezoensis)在封闭体系中进行了加水模拟实验,研究了多细胞宏观底栖藻类在不同演化阶段的生烃能力及产物特征,并与浮游藻及海生单细胞藻类的模拟试验结果进行了对比。实验结果表明:随着温度的升高,多细胞宏观底栖藻类生烃率呈双峰分布。宏观底栖藻类的油气生成潜力低于浮游藻和单细胞藻类,且生成的油质较差。但宏观底栖藻和单细胞藻在高、过成熟阶段具有较好的生气潜力。The pyrolysis experiment of natural porphyra yezoensis was carried out in a closed system. The hydrocarbon-generation potential of multi-cellular benthic macro alga and its products were investigated. The test showed that the benthic macro alga appeared double peaked hydrocarbon production rate while temperature ascending. The multi-cellular benthic macro alga has a relatively lower hydrocarbon-generation potential and poor quality of liquid hydrocarbon as compared with the single cellular and plankton alga. In comparison with plankton alga, the multi-ellular benthic macro alga and the single cellular alga have much more potential to form gaseous hydrocarbon in the high maturity and post maturity stages.
