摘要
利用焦油馏分中的有效成分合成出水煤浆萘油添加剂与蒽油添加剂,应用傅立叶变换红外光谱对萘油、蒽油添加剂的结构进行了分析,推测出萘油、蒽油添加剂主要为含有-CH2-,-SO3-等基团的芳香族化合物。以纯萘磺酸缩甲醛、萘油添加剂及蒽油添加剂分别对庞庄煤进行制浆实验,结果表明:萘油添加剂与蒽油添加剂复配使用时,浆体性能优良。同时对焦油馏分添加剂改善水煤浆性能的作用机理进行了探讨。
The additives for coal water slurry （CWS） were prepared using the effective components of naphthalene oil and anthracence oil. The functional groups of additives have been investigated by Fourier Transform Infrared Spectrography （FFIR）, indicating that the additives are some aromatic compounds with - CH2-,-SO3- functional groups. Experiments of CWS＇ preparation with the additives synthesized and naphthalenesulfonic acid formaldehyde condensation product show that the mixtures of the additive from naphthalene oil and anthracence oil have a good property. Additionally, mechanisms for additive improving CWS＇ property have also been studied.
