摘要 为开发适应中国废弃油脂生物柴油转化的成套技术与装备,结合美国Biopro380型设备,对中国的4种典型废弃油脂生物柴油转化工艺进行了系统研究,结果表明,甲醇回流温度65℃下,酯化反应时间2.5h、浓硫酸加入量0.5%、甲醇与游离脂肪酸摩尔比2.7:1时,酯化混合物的酸值降至1~2mg/g;转酯化反应在醇油摩尔比6:1、催化剂NaOH的加入量1.0%(与废弃油脂的质量百分比)、反应时间60min时,转酯化效果最佳;将该工艺条件应用于Biopro380型设备中进行验证试验,获得的生物柴油产品质量指标基本符合中国生物柴油标准GB/T20828-2007。 为开发适应中国废弃油脂生物柴油转化的成套技术与装备,结合美国Biopro380型设备,对中国的4种典型废弃油脂生物柴油转化工艺进行了系统研究,结果表明,甲醇回流温度65℃下,酯化反应时间2.5h、浓硫酸加入量0.5%、甲醇与游离脂肪酸摩尔比2.7:1时,酯化混合物的酸值降至1~2mg/g;转酯化反应在醇油摩尔比6:1、催化剂NaOH的加入量1.0%(与废弃油脂的质量百分比)、反应时间60min时,转酯化效果最佳;将该工艺条件应用于Biopro380型设备中进行验证试验,获得的生物柴油产品质量指标基本符合中国生物柴油标准GB/T20828-2007。
