Discussion of n-d-M method for calculating aromatic carbon ratio of direct coal liquefaction solvent oil 用n-d-M法计算煤直接液化溶剂油芳碳率的方法探讨
But black carbon asphaltenes contains more aromatic carbon, oxygen-function groups, and less aliphatic chains. 但碳黑沥青质与原油沥青质也是不同的,碳黑沥青质的分子结构中含有更多的芳香结构组分和含氧基团,较少的脂肪侧链组分。
Characterization of aromatic carbon in kerogen and coal with infrared spectroscopy 用红外光谱表征干酪根和煤的芳碳量
The aromatic carbon increasing from humic acid, kerogen to black carbon, and structure become more condensed, rigid, and stable. 腐殖酸大分子结构中芳香化合物组分最少,稳定性最差;干酪根的芳香碳(AC)结构和稳定性比腐殖酸高,碳黑具有更高和更致密的芳香性结构,稳定性也最高。
The experimental results show that hydrophilic oxygen-containing functional groups reduced constantly, aromatic carbon structure increase gradually after dewatering and upgrading. 实验结果表明,改性提质过程中,褐煤中亲水性含氧官能团不断减少,芳香碳(AC)结构则逐渐发展、增加。
