2019年3月20日 However, these standards mainly focus on the emission of fine particulate matter, sulfur dioxide, and oxides of nitrogen, without mentioning VOCs (Liu and Yuan, 2016). Reducing VOC emissions from the coking industry is vital to achieving the VOC emission reduction target by 2020, yet research and control policies remain insufficient.
