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 400-600 °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.
首次使用小型反应器对产油酵母沼泽红酵母CM33进行热解以生产生物油和生物炭。该菌株具有高脂肪含量，主要脂肪酸与植物油相似。热解前，使用喷雾干燥器对酵母进行脱水。探索了400-600℃范围内的热解温度，以获得生物油和生物炭生产的最佳条件。结果表明，在550℃时生物油产量最高可达60%。模拟蒸馏气相色谱表明，生物油含有2.6%的重石脑油、20.7%的煤油、24.3%的生物柴油和52.4%的燃料油。此外，尝试采用短程蒸馏技术进一步纯化生物油。还对生物炭的性质进行了表征。这项工作的成果可为从产油酵母可持续生产固体和液体生物燃料产品铺平道路。
