降低生物柴油生产成本的研究进展

Research development in reducing production cost of biodiesel

综述了除政策因素外,降低生物柴油生产成本的5种方法:选择含油率高、再生周期短、适应贫瘠土地及不同气候条件的新型植物原料;研究新型固体催化剂;引入新工艺(超临界法和超声波法);使用比较简便的方法将废弃的甘油转化为高附加值的产品(环氧氯丙烷、1,3–丙二醇、丙酮醇等)以及适度生产规模等。

Besides policy factors, five methods of cost-cutting of biodiesel are reviewed, including new raw material with higher oil content, shorter regeneration cycle, which is suitable for infertile soil and different climatic conditions; heterogeneous catalysts： new technologies （e.g. supercritical methanol and ultrasonics） ： higher added value utilization of by-product glycerin with simple method （propylene oxide chloride, 1,3-propanediol, pyruvic alcohol etc. ） and moderate scale of production.
