【摘要】：通過3種方法研究調(diào)整稻米油生物柴油的組成對其低溫流動性的改善,一是向稻米油中加入菜籽油,二是向甲醇中添加支鏈醇,三是向稻米油中加入石化柴油。結(jié)果表明:3種方法均能有效改善生物柴油的低溫流動性;在稻米油中加入一定量的菜籽油后,生物柴油的脂肪酸組成發(fā)生了改變,飽和脂肪酸甲酯含量減少,不飽和脂肪酸甲酯中的亞麻酸甲酯含量增加,當(dāng)菜籽油添加量為30%時,生物柴油的低溫流動性最好;在甲醇中添加支鏈醇后,生物柴油中棕櫚酸甲酯含量大幅度減少,支鏈酯含量很少,生物柴油的低溫流動性提高;在稻米油中加入一定量的石化柴油后,混合燃料的產(chǎn)率有所下降,生物柴油的低溫流動性得到有效改善,當(dāng)煤直接液化柴油的添加量為70%時,混合燃料的冷濾點低至-19℃。
[Abstract]:Three methods were used to improve the low temperature fluidity of rice oil biodiesel by adding rapeseed oil into rice oil and adding branched alcohol to methanol. The results showed that the low temperature fluidity of biodiesel could be improved effectively by adding petrochemicals into rice oil, and the fatty acid composition of biodiesel changed after adding a certain amount of rapeseed oil to rice oil. The content of saturated fatty acid methyl ester decreased, and the content of linolenic acid methyl ester in unsaturated fatty acid methyl ester increased. When the amount of rapeseed oil was 30%, the low temperature fluidity of biodiesel was the best. The content of methyl palmitate in biodiesel was greatly reduced, the content of branched chain ester was little, the low temperature fluidity of biodiesel was improved, and the yield of mixed fuel decreased after adding a certain amount of petrochemical diesel into rice oil. The low temperature fluidity of biodiesel was improved effectively. The cold filtration point of the mixed fuel was as low as -19 鈩，
