利用焦化废水代替清水制备焦化废水-煤浆（CWCS），作为液体燃料用于燃烧和气化。表面活性剂在煤表面的吸附对煤浆的制备和工业应用具有重要影响，因为它是改善煤表面润湿性的关键。研究表面活性剂在煤表面的吸附动力学有助于掌握表面活性剂在煤表面的吸附行为。研究了焦化废水中的酚、喹啉、吲哚、氨氮和金属离子等内部组分对煤吸附表面活性剂动力学的影响。吸附动力学测定拟合的吸附容量的表面活性剂在不同的吸附时间与伪一级，伪二级，和粒子内扩散模型。分析了焦化废水内部组分对水煤浆成浆特性的影响。结果显示...
Coking wastewater, instead of clean water, is used to prepare coking wastewater–coal slurry (CWCS), which can be used as liquid fuel for combustion and gasification. Surfactant adsorption on coal surfaces affects the preparation and industrial application of coal slurry because it is essential for improving the surface wettability of coal. The study of the adsorption kinetics of surfactants on coal surfaces contributes to mastering the adsorption behavior of surfactants on coal surfaces. In this work, we focused on the influence of the internal components (phenol, quinoline, indole, NH4+–N, and metal ions) of coking wastewater on the adsorption kinetics of surfactants on coal. Adsorption kinetics was determined by fitting the adsorption capacity of surfactants at different adsorption times with the pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. Then, the effects of the internal components of coking wastewater on the slurrying characteristics of CWCS were analyzed. Results sho...
