技术领域
本发明涉及燃料油技术领域，特别是涉及一种低碳甲醇燃料油及其制备方法。
背景技术
近年来，在原料油中添加一定量的醇或其衍生物，使燃料油燃烧更充分，从而降低碳氧化合物的排放量，不仅推动了绿色环保的生产理念，还缓解了石油紧缺的问题，所以这使得醇基燃料油在市场上备受欢迎。CN102154039B公开了一种高清醇基燃料油，该燃料油主要由二茂铁、洗油、甲醇、甲苯、丙酮和异丁醇复配而成，其不仅节能环保还具有一定的抗爆效果。CN101508917B公开了一种复合醇基燃料油，该复合醇基燃料油中包含甲醇、煤化工轻油、生物柴油、生物重油和一些添加剂，以低成本甲醇资源代替高价原油资源，节约了燃料油的成本。虽然甲醇基燃料油具有清洁排放，成本低廉的特点，但它仍存在热值低、消耗量大、闪点低的一些弊端。随着市场安全要求的屡次升级，以甲醇为代表的醇基燃料油逐渐不能适应新的标准，因此开发一种安全高效的新型甲醇醇燃料油将是未来燃料油发展的必然选择。

优选地，该燃料油包含如下以质量分数计的原料：甲醇55.2％、甘油10％、柴油25.5％、二甲苯1％、过氧化氢3.5％、聚乙烯吡咯烷酮2％、聚丙烯酰胺2.2％、甲基环戊二烯三羰基锰0.5％、γ-巯丙基三甲氧基硅烷0.2％、氯酸钾0.9％。
本发明还提供了一种低碳甲醇燃料油的制备方法，该制备方法包括如下步骤：
步骤1：将5-10％甘油和10-30％柴油输送至反应釜中，打开乳化混合搅拌装置，对燃料油进行循环搅拌，再打开加热装置并将55-65％甲醇、0.2-2％二甲苯充分混合后缓慢地将其加入到反应釜中，与燃料油进行混合、乳化；
步骤2：将0.5-3％聚乙烯吡咯烷酮、0.5-3％聚丙烯酰胺、0.05-0.5％甲基环戊二烯三羰基锰、0.1-0.5％γ-巯丙基三甲氧基硅烷，通过不同输料管输送至反应釜中，待全部加完后，对混合物进行高速分散；然后加入2-5％过氧化氢、0.2％-1％氯酸钾，并打开通气设备，通入氮气，并对反应釜中物料进行3-6h的搅拌处理，即得到一种低碳甲醇燃料油。
优选地，步骤1所述的搅拌为在5000-1000rpm转速下进行。
优选地，步骤1所述的加热为在70-90℃下进行。
优选地，步骤2所述的高速分散为在6000-10000rpm转速下进行。
优选地，步骤2所述的氮气的通入速度为2-10L/h。
与现有技术相比，本发明的技术方案具有如下有益效果：
(1)本发明制备的甲醇燃料油是一种低碳环保型可再生燃料，其具有原料易得、价格便宜、无毒无害高热值、低能耗、低凝点、高闪点，不受低温环境或高温环境所影响的特点，其具有稳定的使用效果，这对于燃料油的开发具有十分重要的现实的意义。
(2)本发明制备的甲醇燃料油是由甲醇、甘油、柴油、二甲苯、过氧化氢、聚乙烯吡咯烷酮、聚丙烯酰胺、甲基环戊二烯三羰基锰、γ-巯丙基三甲氧基硅烷、氯酸钾、组成的，其本身含氧量高，燃烧时需氧较少且燃烧充分；其不含硫和重金属等物质，燃烧后不会产生黑烟以及废气、废渣、废液等污染物，适宜餐饮业以及供热等行业使用，有利于环保节能减排。
(3)本发明中，过氧化氢、氯酸钾作为助燃剂，扩大了该燃料的燃烧条件范围，提高燃料的可燃性；聚乙烯吡咯烷酮、聚丙烯酰胺高闪点慢溶剂可以提高燃料油的整体闪点，并且聚丙烯酰胺具有易形成氢键的酰胺基，可帮助各组分互相充分溶解，提高燃料油长时间的稳定性；高沸点的甘油、低熔点的甲醇以及防爆剂甲基环戊二烯三羰基锰、抗氧化剂γ-巯丙基三甲氧基硅烷的加入同样有助于燃料油稳定性和使用安全性的提高。
