Description

一种环保高氢能生物醇油燃料及其制备方法
技术领域
本发明属于燃料技术领域，具体涉及一种环保高氢能生物醇油燃料，还涉及上述的生物醇油燃料的制备方法。
背景技术
生物醇油，其实就是醇基液体燃料的俗称，生物醇油是以甲醇（如甲醇、乙醇、丁醇等）为主要原料，按特定工艺配方，经化学勾兑合成的一种高清洁生物质液体燃料。它是以液体或者固体形式存在的。它也是一种生物质能，和核能、太阳能、风力能、水力能一样，是各国政府目前大力推广的环保洁净能源；面对石化能源的枯竭，生物醇油是最有潜力的新型替代能源，深受各国企业组织的青睐。生物醇油经过十余年的实验与实践，证明完全可以被市场所接受，并得到广大用户的一致好评。生物醇油的主要原料是甲醇，工业酒精中就含有大量的甲醇，属于中等毒性产品与酒精相当，但经科学工艺生产出符合国家标准的醇基液体燃料，燃烧排放是安全、清洁、符合环境标准。
生物醇油的主要优点有：1、原料广泛，成本低廉。配制燃料的原料甲醇各地化工厂、化肥厂和化工市场都有销售。可就近采购加工，就地销售。利用我单位提供的乳化济配置的新型生物醇油，热值可高达8600大卡/千克，与石油液化气的热值相当，成本仅为石油液化气或柴油的1/2左右，利用空间极大。
2、清洁卫生，绿色环保。该燃料含氧量高，燃烧充分，无黑烟、无积碳、不黑锅底、无残液残渣，燃烧后的废汽排放比石油液化气低80%以上，是名副其实的清洁燃料。
3、安全可靠，适用范围广。该燃料在常温常压下储存、运输和使用，无需高压钢瓶，用普通铁桶或塑料桶封口储存即可，使用方便，万一失火，用水即可扑灭，不会引发爆炸的危险，也不会因泄漏而引发中毒事件。
发明内容
为了解决上述的技术问题，本发明提供了一种环保高氢能生物醇油燃料，还提供了上述的生物醇油燃料的制备方法。
本发明是通过下述的技术方案来实现的：
一种环保高氢能生物醇油燃料，包括以下重量份数的原料：
甲醇 30-40
无水乙醇 20-30
甲缩醛1-6
油酸1-8
乙酸乙酯2-7
二甲氧基甲烷3-8
叔丁醇4-9
吐温80 0.05-0.2
生物乙醇 50-80。
优选的，上述的环保高氢能生物醇油燃料，包括以下重量份数的原料：
甲醇 32-38
无水乙醇 22-28
甲缩醛1-5
油酸1-7
乙酸乙酯2-6
二甲氧基甲烷3-7
叔丁醇4-8
吐温80 0.05-0.18
生物乙醇 60-75。
更优选的，上述的环保高氢能生物醇油燃料，包括以下重量份数的原料：
甲醇 35
无水乙醇 25
甲缩醛4
油酸5
乙酸乙酯5
二甲氧基甲烷5
叔丁醇6
吐温80 0.15
生物乙醇 60。
环保高氢能生物醇油燃料的制备方法，包括下述的步骤：取甲醇30-40份、无水乙醇 20-30份、甲缩醛1-6份、油酸1-8份、乙酸乙酯2-7份、二甲氧基甲烷3-8份、叔丁醇4-9份、吐温80 0.05-0.2份、生物乙醇 50-80份，搅拌，混合均匀，得环保高氢能生物醇油燃料。
生物乙醇的制备方法如下：
取木质纤维素，加入复合酶，水解；所采用的复合酶为β-葡糖苷酶、木聚糖酶、甘露聚糖酶；β-葡糖苷酶、木聚糖酶、甘露聚糖酶的重量比为1-4：2-5：1-3。优选的，β-葡糖苷酶、木聚糖酶、甘露聚糖酶的重量比为3：3：2。
本发明中采用酶水解，相对于酸水解或碱水解等方法，由于酶对其所催化的反应具有很高的反应选择性，并且不会在稀酸水解过程中生成有毒物质，酶还具有其它的优势，酶是天然形成的可生物降解的化合物。本发明的酶主要是通过外切葡聚糖从链端断开的β-1，4糖苷键进行，这种酶有隧道式封闭活性中心，其中容纳一个单独的葡聚糖链，阻止它与纤维素晶体重新连接。
获得水解物之后，加入微生物菌丙酮丁醇梭菌粉、解糖热解纤维素菌粉，于37-45℃下发酵10-15小时；丙酮丁醇梭菌粉、解糖热解纤维素菌粉的重量比例为1-3：1-5。
蒸馏，获得生物乙醇。蒸馏后，在生物反应器中会存在大量的水，为了生产可用的乙醇，必须通过蒸馏过程除去液体洗涤过程剩余的水，蒸馏是纯化液体并将液体混合物分离成各单独组分的方法，是利用不同的沸点将两种液体分离的方法。本发明中，为了分离沸点不同的液体混合物，对液体进行加热使各组分变成气态形式，然后冷凝回到液体形式并进行收集，然后为了得到较高纯度的产品，需要进行多次蒸馏，由于乙醇比水蒸发快，乙醇通过管道上升，然后收集并冷凝进入另一容器中，水留在后面。由于形成低沸点的水-乙醇共沸物，乙醇产品最终纯度限制在95-96%之间，本发明所获得的生物乙醇就是纯度为95-96%的乙醇。
发明的有益效果在于，采用本发明的方法所得的燃料，具有高氢能的特点，而且采用了大量的来自于木质纤维素发酵所得的生物醇，其成本较低。
