Properties of Coal Water Slurry Prepared with Low-rank Coal and Oil-field Sewage from Xinjiang
摘要
Abstract
The properties of coal water slurry (CWS) prepared by low-rank coal and oilfield sewage were investigated.The results show that the maximal CWS mass fraction for each coal follows:Wusuhongshan coal (66.5％)＞Wususikeshu coal (61.0％)＞Xukuang 4 coal (53.4％).Compared with the CWS prepared by oil-free sewage,the CWS prepared by oil-bearing sewage for each coal have lower viscosity,which decrease by 30.3％ and 66.8％ for Wusuhongshan coal and Wususikeshu coal respectively,and have larger mass fraction,which increase by 1.1％ for Xukuang 4 coal.It indicates that the use of oil-bearing can promote the mass fraction and calorific value of CWS,as well as simplifying the treatment of oil-field sewage.Among three kinds of CWS,the Wusuhongshan CWS has the largest stability due to its high ash content.The stability of CWS is largely affected by coal type and additive,while the type of water or sewage shows little effect.关键词
