Volatile fatty acids from oxidation liquefaction of the end-of-life wind turbine blades - GC analysis

The oxidative liquefaction method was used to get the chromatographic data shown here. This method has been used to break down the polymer matrix of wind turbine blades and measure the resin degradation yield. In this experiment, the effects of five different parameters, such as reaction temperature, residence time, pressure, waste-to-liquid ratio, and oxidant concentration, on resin degradation were studied in detail. Experiments were performed in the temperature range of 250°C to 350°C with a residence time of 30 to 90 minutes, at a pressure of 20 to 40 bar, a waste-to-liquid ratio of 5-25%, and oxidant concentrations of 15-45% by weight. The GC method was used to analyse an achive liquid sample after the oxidative liquefaction process.
