Algae after extraction with hexane are a promising feedstock for fuel production (such as hydrogen gas) using supercritical water gasification. However, the effect of extraction with hexane on supercritical water gasification has not been elucidated so far. In this study, original sample and sample after extraction with hexane of microalgae Chlorella vulgaris were gasified in supercritical water at 600 °C and 25 MPa and the results were compared. Algae after extraction with hexane resulted in a lower methane content and lower carbon gas yields. Rate constants for reactions in the algae decomposition reaction network were determined by fitting calculation to experimental data.

用己烷萃取后的藻类是使用超临界水气化生产燃料（例如氢气）的有前途的原料。但是，到目前为止，尚未阐明用己烷萃取对超临界水气化的影响。在这项研究中，将原始样品和微藻小球藻的己烷萃取后的样品在600°C和25 MPa的超临界水中气化，并比较结果。用己烷萃取后的藻类降低了甲烷含量，降低了碳气收率。通过拟合实验数据确定藻类分解反应网络中反应的速率常数。
