Description

醇基燃料的制备方法
技术领域
本发明涉及化工领域，具体涉及醇基燃料的制备方法。
背景技术
醇基燃料就是以醇类(如甲醇、乙醇、丁醇等)物质为主体配置的燃料。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，醇基燃料是最有潜力的新型替代能源，深受各国企业组织的青睐。
醇基燃料有明显的经济可比性——和液化气、柴油、煤油相比，热效率高是它最佳的特点。醇基燃料是绿色环保能源——和煤、煤焦油、重油、柴油、汽油相比，醇基燃料燃烧最完全彻底，热转换效率最高，排放是水与二氧化碳为主，是未来最清洁、最环保、最有发展潜力的燃料。
目前的醇基燃料燃烧的火焰多为橙色，火焰温度约为1000℃左右，且燃料消耗较快。
发明内容
本发明的目的在于提供醇基燃料的制备方法，使用该方法制备的醇基燃料燃烧的火焰为蓝色，火焰温度达1100℃。
为达到上述目的，本发明的基础方案为：醇基燃料的制备方法，包括以下步骤：
(1)配制乳化剂：按照质量百分比，准备2.5％的氢氧化钾、2.5％的氢氧化钠、10％的水、30％的甲酸乙酯和55％的乙醇；将氢氧化钾和氢氧化钠加入水中溶解，然后再加入甲酸乙酯和乙醇，混匀后密封，静置3h；
(2)将3～5kg配制好的乳化剂缓慢加入1000kg精甲醇中；搅拌0.5h，得混合物I；
(3)在混合物中缓慢加入100kg水，并搅拌均匀，得混合物II；
(4)取10g二茂铁，先将二茂铁溶解于精甲醇中，得二茂铁溶液；然后将二茂铁溶液缓慢加入混合物II中，混匀得混合物III；
(5)取1.8～2kg硫酸溶液，先将硫酸溶解于精甲醇中，得硫酸的甲醇溶液；然后将硫酸的甲醇溶液缓慢加入混合物III中，得混合物IV；将混合物IV缓慢搅拌0.5h，密封后沉淀4h。
乳化剂起稳定和助燃的作用。夏天温度高，加入3kg的乳化剂就可助燃，冬天温度低，需要加入5kg的乳化剂才能顺利助燃。
本方案与传统技术的区别在于添加了硫酸溶液。传统技术生产的醇基燃料燃烧时为橙色，火焰温度约为1000℃，燃料消耗较快。按照本方案制备的醇基燃料，燃烧时火焰呈蓝色，火焰温度达到1100℃，燃料消耗慢。
优化方案一：作为对基础方案的优化：步骤(1)和步骤(3)中的水为经过纯净水过滤器处理的纯净水。自来水中还有杂质，若直接配置醇基燃料，容易在使用过程中堵塞管道。经纯净水过滤后的纯净水将杂质滤掉，管道不易被堵塞，增加了管道的使用寿命。
优化方案二：作为对优化方案一的优化：精甲醇的纯度为99.99％。使用精甲醇配置的燃料，更易燃烧，且火焰更旺。
优化方案三：作为对优化方案二的优化：硫酸溶液的体积浓度为94％。使用该浓度的硫酸不仅可以起到增大火焰和增加火焰温度的作用，而且相比纯浓硫酸来说，节约成本。
具体实施方式
下面通过具体实施方式对本发明作进一步详细的说明：
醇基燃料的制备方法，包括以下步骤：
(1)配制乳化剂：按照质量百分比，准备2.5％的氢氧化钾、2.5％的氢氧化钠、10％的水、30％的甲酸乙酯和55％的乙醇；将氢氧化钾和氢氧化钠加入水中溶解，然后再加入甲酸乙酯和乙醇，混匀后密封，静置3h；水为经过纯净水过滤器处理的纯净水；
(2)将3～5kg配制好的乳化剂缓慢加入1000kg纯度为99.99％的精甲醇中；搅拌0.5h，得混合物I；
(3)在混合物中缓慢加入100kg纯净水，并搅拌均匀，得混合物II；
(4)取10g二茂铁，先将二茂铁溶解于精甲醇中，得二茂铁溶液；然后将二茂铁溶液缓慢加入混合物II中，混匀得混合物III；
(5)取1.8～2kg体积浓度为94％的硫酸溶液，先将硫酸溶解于精甲醇中，得硫酸的甲醇溶液；然后将硫酸的甲醇溶液缓慢加入混合物III中，得混合物IV；将混合物IV缓慢搅拌0.5h，密封后沉淀4h。
通过该方法制备的醇基燃料，燃烧时火焰呈蓝色，火焰温度达到1100℃，比传统技术生产的无硫酸的醇基燃料高100℃。当按照本发明方法制备的醇基燃料与同等体积的传统技术生产的无硫酸的醇基燃料同时燃烧时，在火焰面积同等大的情况下，传统技术制备的燃料消耗快，使用时间较短；本发明制备的燃料消耗慢，使用时间较长。
以上所述的仅是本发明的实施例，方案中公知的使用方法及特性等常识在此未作过多描述。应当指出，对于本领域的技术人员来说，在不脱离本发明的前提下，还可以作出若干改进，这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准，说明书中的具体实施方式等记载可以用于解释权利要求的内容。
