　　【化工仪器网政策标准】改革开放以来，随着国民经济的迅速发展，国家能源需求剧增，我国原油产量与消费量之间的缺口不断扩大。而汽车作为能源消耗大户，其消耗的石油占石油消耗总量约 50%左右。另一方面汽车排放的 CO、NOx、HC、颗粒物、苯、醛酮等污染物对人类赖以生存环境的影响越来越大，并在很大程度上制约了可持续发展。

　　为减少车辆对石油的依赖，保障我国的能源安全，保护生态环境，我国展开了车用代替燃料相关研究。汽车可能的替代燃料包括天然气、液化石油气、醇类、醚类和氢燃料等，其中，醇类燃料中的甲醇和乙醇原料来源广泛，物理化学性质、热工参数等与汽油接近，可以直接应用在汽车上，无须对现有汽车燃油系统进行太多改造，是较为理想的代替燃料。

　　但由于甲醇燃料的特殊性，甲醇燃料车除排放上述常规污染物以外，还会排放甲醛、甲醇等非常规污染物，而目前我国还没有规定统一的甲醇燃料汽车和发动机排放的甲醇、甲醛等非常规污染物排放测试方法。因此要大力开发甲醇汽车，落实八部委“61 号文件”中对甲醇和甲醛排放的控制要求，就需要补充制定甲醇车排气中甲醛和甲醇的测量方法标准，解决甲醇燃料带来的特殊尾气排放问题。

　　日前，近日生态环境部印发了《甲醇汽车非常规污染物排放测量方法(征求意见稿)》，面向有关单位征集意见。有建议或意见者，可以在2020年7月15日前反馈至生态环境部。

　　该标准主要内容框架包括适用范围、规范性引用文件、术语和定义、污染物测量、试验用燃料、信息公开要求、标准的实施、附录等，规定了燃用甲醇燃料的轻型汽车、重型发动机和汽车，包括使用甲醇单一燃料和甲醇—柴油双燃料的发动机和汽车排气中甲醛和甲醇的测量方法。其他燃用与甲醇相关燃料的汽车、发动机排放非常规污染物的测量，也可参照该项标准执行。

　　值得关注的是，该标准在附录中规定了燃用甲醇燃料的汽车和重型发动机排气中甲醛和甲醇采样、分析、测定方法。其中，附录A规定了燃用甲醇燃料的汽车和重型发动机排气中甲醛和甲醇的采样方法，包括采样系统、方法、运输和保存，以及采样过程中的质量保证和控制等内容。附录B规定了燃用甲醇燃料的汽车和重型发动机排气中甲醛检测的高效液相色谱法。附录C则规定了燃用甲醇燃料的汽车和重型发动机排气中甲醇检测的固相吸附/顶空—气相色谱质谱联用法。

　　无论是从汽车行业转型升级方面来说，还是从能源保护或是环境保护方面来说，新能源汽车都是一个趋势。甲醇汽车非常规污染物排放测量方法标准的制定，有助于促进甲醇汽车发展，也有助于环境保护及能源保护。
