Microalgae (Scenedesmus obliquus) produced in flat panel photobioreactors were converted via supercritical water gasification at 650°C, 28 MPa and a residence time of 3 minutes. The long term aim is to gain a higher process efficiency through recycling of byproducts of supercritical water gasification and waste water during the cultivation of microalgae. The first step of the project, the general feasibility of conversion of microalgae via supercritical water gasification to a hydrogen-rich combustible gas is presented. The product gas consisted of hydrogen, methane, carbon dioxide, and ethane. A product gas with a higher heating value of 36 to 38 MJ/kg TOC could be reached, the carbon gasification yield was 64% respectively 69,5% in the two first experiments.
