| 摘 要： | 介绍了国内外水煤浆气化技术的发展历程，研究了国家水煤浆工程技术研究中心研发的“分级研磨高浓度制浆工艺”的提浓效果及其对气化水煤浆技术发展的推动作用。选取了一种无烟煤进行成浆性试验。结果表明：在传统制浆工艺下，该煤样的制浆浓度即可达到62％，若采用分级研磨制浆工艺，可使制浆浓度提高至65％，可作为气化水煤浆的制浆用煤。进行了不同粒度条件和加入催化剂情况下煤浆的热天平试验，分析了不同试验条件下样品的失重与失重速率数据。试验证明了该煤样的气化反应活性可通过一定手段提高，结合工业实践，分析了低挥发分煤制备气化水煤浆的可行性。

| Abstract: | Introduce the development history of coal water mixture （CWM） for gasification at home and abroad. Investigate the influence of classified grinding high concentration CWM preparation process, developed by the National CWM Engineering and Technology Center, on CWM concentration improvement and CWM gasification technologies development. Taking one anthracite as experimental coal sample, compare traditional method and classified grinding high concentration CWM preparation method. The results show that, the concentration of CWM compared by the former is 62 percent, while the latter is 65 percent. Conduct the thermo-balance test by changing the particle size and adding catalyst. Analyze the weight loss and weight loss rate of CWM samples. The test proves that, the gasification reactivity of coal sample can be improved by certain methods. Analyse the feasibility of low volatile coal to CWM for gasification combined with industrial practice. |
