针对现有技术中的不足之处，本发明提供一种一种低油耗汽车甲醇合成燃料。
为了上述目的，本发明技术方案如下：
一种低油耗汽车甲醇合成燃料，其特征在于：由甲醇、芳香烃、精碳五轻油、溶剂油、凝析油、MTBE、汽油抗爆剂及催化剂组成，其重量组成：其中甲醇、芳香烃、精碳五轻油、溶剂油、凝析油、MTBE按照重量比25∶30∶20∶10∶8∶7或者15∶30∶30∶10∶8∶7的比例调配；其中25∶30∶20∶10∶8∶7为最佳配比；催化剂包括有机金属缓蚀剂、抗氧化剂和橡胶溶胀剂；汽油抗爆剂分为抗爆剂A和抗爆剂B。
所述有机金属缓蚀剂由甲醇、笨并三唑和笨胺混合溶解而成；将甲醇、笨并三唑和笨胺按重量比3∶5∶2搅拌溶解，8小时后用200目筛过滤去渣后，制得有机金属缓蚀剂。
所述抗氧化剂由T501按重量比1∶3溶解于甲醇并放置2小时制成。
所述橡胶溶胀剂由甲醇、二辛脂和月桂醇按重量比为1∶1∶1混合溶解而成；先将甲醇和二辛脂按重量比1∶1混合充分搅拌，再加入同等重量的月桂醇混合搅拌，放置8小时制成。
所述抗爆剂A由甲基环戊二烯三羰基锰、MTBE、异辛烷和正庚烷按重量比25∶442∶290∶4混合溶解并调和搅拌20分钟制成。
所述抗爆剂B由TAME、膦酸二甲酯、基甲酸和甲基萘混合溶解而成；将TAME、膦酸二甲酯、甲酸，、甲基萘按重量比35∶45∶15∶5混合搅拌20分钟。
一种低油耗汽车甲醇合成燃料的制备方法，其特征在于：包括以下步骤：
(1)甲醇电解制氢：将纯度大于99.5％的甲醇放入干燥洁净的容器内使用22V电流进行40分钟电解制氢，总反应为：CH3OH+H2O＝3H2+CO2，经过电解制氢后的甲醇可以提高7％-8％个单位的辛烷值；
(2)将电解制氢后的甲醇，芳香烃，精碳五轻油，溶剂油，凝析油，MTBE原料按照重量比25∶30∶20∶10∶8∶7或者15∶30∶30∶10∶8∶7的比例分别进入原料罐，调制成母液；
(3)将有机金属缓蚀剂、抗氧化剂、橡胶溶胀剂、抗爆剂A或者抗爆剂B与母液按照重量比15∶8∶6∶1∶10000的比例加入原料罐；
(4)将上述不同组份的原料混合在一起，进行物理调和，利用循环泵进行内循环上下反复翻搅，翻搅1-2小时；
(5)翻搅完成后，静置8-24小时取样进行化验分析，分析结果合格后方可使用。
有益效果：该燃料有效解决了甲醇汽油高油耗，低动力和难调配的问题。与纯汽油相比，本发明燃料气化燃烧后产生的一氧化碳和氮气化合物含量明显降低。路程公里数较纯汽油提高了10％--25％。载重动力提升10％左右。因而使用本发明燃料与使用汽油相比减少了对环境污染更为有利，相对减少了车主的经济压力，是较为理想的车用替代燃料。
