Development of nanofiber based diesel soot filtration technology

从最近的大众清洁柴油丑闻中可以看出，柴油发动机排放控制的研发对包括加拿大在内的世界都是紧迫而重要的。柴油机烟尘是一种复杂的气溶胶，主要含有碳质颗粒和微量的无机物质和其他吸附物质。烟尘颗粒的直径从10纳米到100纳米不等。作为一种与呼吸系统疾病、心血管疾病以及肺癌有关的主要空气污染物，煤烟每年导致全球数百万人过早死亡。因此，全球范围内出台了越来越严格的法规来控制柴油发动机的烟尘排放，在过去几年中，对柴油烟尘减排技术的研究受到了极大的关注。

As evidenced by the most recent Volkswagen clean diesel scandal, R&D in diesel engine emission control is urgent and important to the world, including Canada. Soot from diesel engines is a complex aerosol containing mainly carbonaceous particles with trace amounts of inorganic material and other adsorbed species. Soot particles range from 10 to 100s nanometers. As a major air pollutant that is associated with respiratory and cardiovascular diseases as well as lung cancers, soot is responsible for millions of premature death annually around the world. As a result, increasingly stricter legislations have been published globally to control soot emissions from diesel engines and research in diesel soot abatement technology has received much interest over the last few years.
