乙二醛和甲基乙二醛直接排放特征数据集

于我国不同地区（包括陕西、山西、宁夏、内蒙古、河北、安徽）采集了十种生物质和煤炭，对不同燃料进行模拟燃烧实验并采集其直接排放的PM2.5样品，针对乙二醛和甲基乙二醛，分析其排放比和排放因子，探讨了不同源排放特征差异的影响因素，并将该结果与气相中乙二醛和甲基乙二醛进行对比，获得来自生物质和煤炭燃烧的乙二醛和甲基乙二醛的直接排放特征。

Ten types of biomass and coal were collected from various regions in China, including Shaanxi, Shanxi, Ningxia, Inner Mongolia, Hebei and Anhui. Simulated combustion experiments were conducted for these fuels, and directly emitted PM2.5 samples were collected. For glyoxal and methylglyoxal, their emission ratios and emission factors were analyzed. The influencing factors causing the differences in emission characteristics among different sources were discussed. Moreover, the results were compared with those of glyoxal and methylglyoxal in the gas phase, and the direct emission characteristics of glyoxal and methylglyoxal from biomass and coal combustion were finally obtained.
