Description
Summary:Fossil fuel reserves have depleted. Therefore, renewable and sustainable energy forms an important issue. Microalgae as a third-generation biomass can be an alternative carbon-neutral fuel source. However, its fuel quality is low. Co-pyrolysis is an important technique to upgrade the fuel quality of microalgae. In this study, we aimed to carry out the pyrolysis of polystyrene and <i>Spirulina</i> sp. microalgae at low temperatures (350, 400, and 450 °C). The experiments were conducted using a semi-batch reactor setup. Co-pyrolytic product yields were calculated. The composition of liquid products was enlightened by using GC-MS. As a result of the analysis, aromatic compounds like styrene and toluene were detected in the co-pyrolytic liquid. Moreover, it was observed that co-pyrolysis increased the solid residue yield while it decreased the liquid and gas product yield.
