Abstract
An oleaginous yeast Rhodotorula paludigena CM33 was pyrolyzed for the first time to produce bio-oil and biochar applying a bench-scale reactor. The strain possessed a high lipid content with the main fatty acids similar to vegetable oils. Prior to pyrolysis the yeast was dehydrated using a spray dryer. Pyrolysis temperatures in the range of 400�0�C were explored in order to obtain the optimal condition for bio-oil and biochar production. The result showed that a maximum bio-oil yield of 60% was achieved at 550�C. Simulated distillation gas chromatography showed that the bio-oil contained 2.6% heavy naphtha 20.7% kerosene 24.3% biodiesel and 52.4% fuel oil. Moreover a short path distillation technique was attempted in order to further purify the bio-oil. The biochar was also characterized for its properties. The consequence of this work could pave a way for the sustainable production of solid and liquid biofuel products from the oleaginous yeast. ? 2023 The Author(s).
