微波促进非均相催化生物柴油制备的研究进展(Advances in Synthesis of Biodiesel Catalysts by Heterogeneous Catalyst Promoted by Microwave)
生物柴油 微波 转酯化 非均相催化剂
2010/12/28
从非均相酸和碱催化转酯化反应的角度,综述了微波促进生物柴油制备的国内外研究进展。在微波辅助下非均相催化过程具有反应速率快、节能、环境友好、产物分离简便的优点。非均相催化剂以固体酸或者固体碱催化剂为主,反应在10~30min内完成,转化率与传统加热方式相当或者更高,所采用的固体催化剂具有可重复利用性。
文冠果种仁油与棉籽油制备生物柴油对比实验(Study on Biodiesel Prepared from Xanthoceras Sorblfolia Bunge Seed Oil and Cottonseed Oil)
生物柴油 文冠果种仁油 棉籽油
2010/12/28
通过酯交换实验制备了以新疆产的文冠果种仁油和棉籽油为原料的两种生物柴油。采用气相色谱方法对其脂肪酸甲酯组分进行了分析;考察了两种生物柴油的部分理化性质,并与0号柴油和国外生物柴油的标准进行对比。重点分析了生物柴油中脂肪酸甲酯组分分布对其理化性能的影响。实验结果表明,文冠果种仁油无需进行脱酸预处理,而各项理化指标均达到要求,更适合制备生物柴油。
废煎炸油制生物柴油全生命周期分析(Life Cycle Assessment of Biodiesel Made of Residual Frying Oil)
废煎炸油 生物柴油 生命周期评价 能源消耗 排放
2010/2/26
运用生命周期评价方法对一种以废煎炸油为原料制取的生物柴油生命周期能耗和排放进行了分析,并将其全生命周期各项指标与传统柴油路线进行了对比,结果显示其化石能源消耗比柴油减少了65.7%,石油消耗较柴油全生命周期减少91.8%,常规排放也都明显降低,温室气体排放中CO2 排放下降88.1%,总的温室气体排放按全球变暖潜值折算后下降86.6%。表明废煎炸油制生物柴油是符合循环经济的环境友好型代用燃料。 T...
