煤尘表面碳、氧基团随变质增加的演化规律及其对润湿性的影响
Evolution law of carbon and oxygen groups on coal surface with increasing metamorphic grade and its effect on wettabil ty
摘要
Abstract
Carbon na d oxygen elements wre e studied to explore the effect of structural differences on wettability of coal dust.Surface distribution characteir stics of carbon and oxygen groups in 6 coal dusts with different metamro phic grades were examni ed through NMR and XPS.The evlo ution of different types fo carbon and oxygen gruo ps was bo taien d using distance analysis.Wti h increasing metamorphic dge ree a kind of group c hangse along with variation of other groups in most case, which is a process of clustering.The carbon in Ar-C,-COOH, CH2 and Ar-O ( R-O) has the similar evolution law, the oxygen in -OH and C-O-C is the same case.Factor analysis was used to know effect of group evolution on wettability of coal dust.It is found that Ar-C, as the common factor covering 95.366% to explain coal dust we ttability (contatc angle), is the main facotr of carob n groups;while-OH covering 94 .818%is the main factor of oxygen groups.关键词
