Description
技术领域
本发明属于石油化工技术领域,具体涉及一种绿色环保的汽油添加剂。
背景技术
随着经济的发展,汽车的普及,汽油的使用量逐年增加。在石油提炼汽油的过程中,普遍采用催化裂化的技术,生产的汽油含有少量有机酸和有机碱,时间长了,汽油中会产生酸碱沉淀,汽油中的烯烃和烯醇长时间会产生氧化反应生成胶状物质,这些物质附着在邮箱或发动机内,会产油垢,影响发动机的性能,并造成高油耗。汽油的燃烧会产生HC、CO和NOx,这些有害物质释放到大气中,造成雾霾,损害人的身体健康。
为了弥补汽油存在的缺陷、改善油品质量和提高其使用性能,已经研发出抗爆剂、抗氧化剂、分散剂、防腐剂、抗静电剂、防胶剂、抗磨剂、抗烧蚀剂、助燃剂、表面活性剂、润滑剂、消烟剂等多种化学添加剂。但是,其使用效果还没有达到绿色环保的要求,如抗爆剂中加有四乙基铅、二茂铁,这些重金属元素导致环境的二次污染。
专利201610977662.3公开了一种汽油添加剂及其制备方法。,其组份按重量份数包括甲基叔丁基醚3-12份、丁醇10-15份、石脑油10-20份、吐温80 3-6份、松香提取液15-25份、异丁烷3-6份、石油醚15-25份、清净分散剂10-25份、月桂醇聚氧乙烯醚10-25份、表面活性剂4-10份以及二乙醇单丁醚10-25份,该汽油添加剂虽然环保无污染,能够提高汽油的燃烧效率,节省汽油,但是,该汽油添加剂燃烧时剧烈,容易发生爆炸,其也没有解决汽油在邮箱和发动机中的积垢问题。

上述汽油添加剂的制备方法为:在常温条件下取上述原料组分,混合,搅拌20-30min,制成。
所述防爆剂为异辛烷,异丁醇,磷酸甲基苯二苯酯中的一种或一种以上。
所述金属腐蚀抑制剂为吡唑酮,甲基丙烯酸酯低聚物,甲基苯并三氮唑,三聚磷酸铝,硬脂酸丁酯中的一种或一种以上。
所述助溶剂为2-甲基-2戊醇,琥珀酸酯,蓖麻油,三乙醇胺中的一种或一种以上。
所述抗氧化剂为BHT501,4-甲氧基邻苯二胺,苯酚,二甲酚,2,6-二叔丁基对甲基苯酚中的一种或一种以上。
所述汽油添加剂还包括羧基封端的丁二烯均聚物与甲基丙烯酸的酯化物3-8份。
所述汽油添加剂还包括钽酸锂1-3份。
所述汽油添加剂还包括碳酸二酰氯与4,4'-亚环己烷基二苯酚的聚合物1-3份。
本发明的有益效果:本发明的汽油添加剂,可以添加到各种型号的汽油产品中,可以降低汽油燃烧产生的HC、CO和NOx有害气体,增加汽油的燃烧值,防爆剂的添加可以防止汽油剧烈燃烧产生爆炸事故,金属腐蚀抑制剂可以有效缓解汽油对于汽车发动机和邮箱的腐蚀及积垢。
