在同样煤浆浓度下,碳转化率越高、吨氢煤耗、氧耗越低的原料煤经济性越好,表6中原料煤经济性由高到低依次为:神优2、陕煤1、尔林兔、马泰壕、印尼煤。4结束语1)原料煤变质程度低、粒度级配合理、一定范围内提高水煤浆添加剂比例、水煤浆温度、pH值都能在一定程度上改善水煤浆成浆性。2)气化炉内温度一般控制在1200~1300℃,低流动温度灰、较低流动温度灰的原料煤均可作为水煤浆气化用煤。3)熔融煤灰可以分为玻璃渣、塑性渣和结晶渣,液态排渣黏度一般控制在5~45Pa·s,其中欣昱、特低灰原料煤灰分的黏度随着温度变化存在一个突变点,属于典型的结晶渣,不适合作为水煤浆工艺的气化用煤。4)从经济运行角度分析,应选用低内水、低灰分、低灰熔点、高挥发分、高可磨指数、高热值、且煤质稳定的原料煤。镇海炼化成功试烧的原料煤经济性由高到低依次为:神优2、陕煤1、尔林兔、马泰壕、印尼煤。参考文献[1] 侯侠,张伟伟. 煤化工科普知识[M]. 北京:中国石化出版社,2013:9-12.[2] 赵忠霞. 不同煤质对水煤浆成浆性能的影响[J]. 内蒙古科技与经济,2016,35(23):92-94.[3] 马乐波. 宁煤集团气化用水煤浆原料煤筛选与制浆工艺研究[D]. 上海:华东理工大学,2016.[4] 吴晓华,潘卫东,杨纯. 水煤浆添加剂对3 种煤的流动性能研究[J]. 煤炭学报,2011,36(3):491-496.[5] 柴志方,张瑞杰,姬文心. 温度对水煤浆稳定性影响的研究[J]. 矿业科学学报,2018,3(4):392-397.[6] 亢万忠. 煤化工技术[M]. 北京:中国石化出版社,2017:158-162.[7] 李德侠. 煤灰熔融及黏温特性的研究[D]. 上海:华东理工大学,2012.A STUDY ON THE COAL AS FEEDSTOCK FOR COAL WATER SLURRY GASIFICATIONGu Wenlong(SINOPEC Zhenhai Refining and Chemical Branch,Ningbo 315200)Abstract:Rude coal from different regions with different metamorphic grade has different performance onvarious aspects. Investigating dozens of rude coal,about ten species were selected as the feedstock for coal water slurry gasification. Burnt test was carried out on new coal species,such as Matai Trench,Shanmei No.1,Erling Rabbit,and Indonesian coal,and evaluation was made for these species from aspects of rude coal composition,coal water slurry formation property,fusibility and viscosity temperature property,and economic benefit.Key words:rude coal;slurry formation;fusibility;viscosity temperature property;economic evaluation
