- 制备了新型固体碱催化剂KNO3/AlSBA-15,并以此催化大豆油与甲醇酯交换反应制备生物柴油,对其工艺条件进行了优化。结果表明:醇油物质的量比为12∶1,催化剂用量为大豆油质量的3%,反应温度65℃,反应时间4 h,生物柴油的产率可达81%以上。该催化剂对酯交换制备生物柴油具有较高的催化活性和良好的重复使用性。
- Abstract:
- New solid basic catalyst KNO3/AlSBA-15 was prepared.The transesterification of soybean oil and methanol to biodiesel catalyzed by KNO3/AlSBA-15 was studied.Optimization of processing parameters for biodiesel from soybean oil was researched.The results showed that the optimum reaction conditions were as following:molar ratio between methanol and soybean oil 12∶1,mass ratio of catalyst to soybean oil weight 3%,reaction temperature 65℃,reaction time 4 h.The yield of biodiesel reached 81% under the optimum reaction conditions.The catalyst for transesterification of biodiesel has higher catalytic activity and good reusability.
