Description

一种调合型生物柴油及其制备方法
技术领域
本发明属于生物柴油技术领域，主要涉及的是一种-10#调合型生物柴油及其制备方法。 
背景技术
随着能源供应形势的日益紧张，对生物柴油的研究日趋深入，已相继报道了五种相关的制备生物柴油的方法，即稀释、微乳化、热解、酯交换及生物技术方法。目前主要采用的是化学酯交换法，但是化学酯交换法合成生物柴油存在以下缺点：工艺复杂，醇必须过量，后续工艺必须有相应的醇回收装置，能耗高、成本高、色泽深，其中不饱和脂肪酸在高温下容易变质。为解决上述问题，人们开始研究用生物酶法合成生物柴油，即用动物油脂和低碳醇通过酶制剂的催化进行转酯化反应，制备相应的脂肪酸甲酯或乙酯。该方法促进了工艺技术的改进和产品质量的提高，国家因此对汽车尾气中有害物质排放量要求逐步降低，对汽车燃料中硫含量、十六烷值等燃油指标提出了更高的标准，酶法合成生物柴油技术随着这些标准的提高同步改进，产品性能均有所提高，与-5#、0#、10#生物柴油相比，-10#生物柴油在低温性能方面表现更加良好。 
发明内容
本发明针对现有技术存在的欠缺，提供一种-10#调合型生物柴油，使其在-10℃温度下存放半年以上不析油脂、不析甲醇，透明稳定，指标达到GB/T20828-2007标准中-10#生物柴油标准。改善了生物柴油的性能，拓宽了应用范围。 
该发明的另一目的在于提供一种-10#调合型生物柴油的制备方法。使生产方法简单、工业化程度高，生产成本降低。 
-10#调合型生物柴油的质量百分比组成是： 
植物油                        20～30 
矿物柴油                      45～60 
十二烷基磺酸钠                0.8～2.0 
OP乳化剂                      1.0～3.0 
三乙醇胺                      0.5～2.0 
甲醇                          10～15 
环烷酸                        1.0～3.0 
生物复合酶                    0.01～0.03 
制备-10#调合型生物柴油的方法是：将植物油与甲醇、十二烷基磺酸钠、OP乳化剂、三乙醇胺按上述质量百分比混合均匀，将该混合液在搅拌情况下缓慢地倒入矿物柴油中，同时按质量百分比要求加入环烷酸、生物复合酶充分搅拌混合即可。 
上述组分中，植物油、矿物柴油、十二烷基磺酸钠、OP乳化剂、三乙醇胺、甲醇、环烷酸、生物复合酶均为符合国家标准的市售产品。 
本发明采用植物油为原料，加入生物复合酶催化剂，改善植物油性能，再加入矿物柴油，混拌制得调合型生物柴油，产品稳定。经过试验：在-10℃温度下存放半年以上不析油脂、不析甲醇，透明稳定，指标达到GB/T20828-2007标准中-10#生物柴油标准。经过工业锅炉和柴油发动机台架试验证明：柴油储存稳定，燃烧稳定，热值高，油路和喷嘴雾化正常，发动机运行稳定。
