准东煤田的煤炭资源预测储量（3900亿吨）占新疆煤炭储量（2.19万亿吨）的17.8%，占全国煤炭资源储量（5.56万亿吨）的7.2%。煤质以长焰煤不粘煤和弱粘煤为主，是我国目前最大的整装煤田。准东煤田煤质以中水分和低灰分含量、中高挥发份产率、低硫、低磷和低氯含量为特征，适用于制备陶瓷窑炉和玻璃熔窑的替代燃料——精细油水煤浆。 本论文以准东煤为原料，在三种不同溶剂(四氢萘、N-甲基吡咯烷酮和柴油)中进行了溶胀实验，研究了煤与溶剂比、溶胀时间、温度、溶剂等对溶胀的影响，并推导出溶胀动力学方程。以准东煤为原料，用干法制备了精细油水煤浆，研究了粒度分布、分散剂种类、分散剂计量和水、柴油、煤质量比等因素对精细油水煤浆粘度的影响。通过研究准东煤与其它不同变质程度煤进行复配后制浆，考察煤变质程度对精细油水煤浆粘度的影响。最后研究了微波改性对精细油水煤浆的影响规律，探索微波辐射功率与精细油水煤浆粘度的规律。得到如下结论： 在溶胀实验中，N-甲基吡咯烷酮体系溶胀率高于柴油和四氢萘体系的溶胀率。煤:溶剂为1:6时，各体系溶胀速率都最大，溶胀度大小顺序是N-甲基吡咯烷酮体系>四氢萘体系>柴油体系。在溶胀时间达到6h时，3个体系溶胀度，都出现最大值，溶胀度大小顺序是：N-甲基吡咯烷酮体系>柴油体系>四氢萘体系。煤在上述溶剂中的溶胀度，随着温度的升高而增大，到75℃后出现拐点，N-甲基吡咯烷酮体系和四氢萘体系的溶胀度开始下降，而柴油体系煤的溶胀度始终是随着温度的升高而降低。这是由于极性溶剂NMP破坏煤大分子间的氢键作用较强，故对煤的溶胀程度较大。 在溶胀机理比较实验中，实验温度在20℃～80℃范围内，温度对溶胀度的影响不大，煤在柴油中的平衡溶胀度约为1.139。采用吸附溶胀法和Suuberg溶胀法对准东煤的溶胀行为进行分析比较，推导出吸附溶胀法二级动力学方程为dx/dt=K(1-AQ_S x)(1-x)，其动力学方程的溶胀活化能为1.105kJ/mol。吸附溶胀法能很好的描述煤粉溶胀行为。 正交实验及单因素实验优化的制备精细油水煤浆工艺参数为：分散剂吐温80为1.3g、水30g、柴油35mL和42.5g准东煤（d50为6.26 um煤粉和d50为35.1 um煤粉质量比为8:2）。在最优条件下制备精细油水煤浆的粘度是217mPa•s，煤浆浓度是42.1%，在60℃以下煤浆的表观粘度符合国家煤浆技术条件。 配煤制浆实验中，低变质程度煤的配入，总体上表观粘度不如高变质程度煤。以高变质程度煤配煤制浆过程中，当准东煤:高变质程度煤为9:1时，配入黄陵煤优于晋城寺河煤，其它比例时晋城寺河煤优于黄陵煤。配入高变质程度煤和低变质程度煤，其表观粘度值都大于准东煤最优条件下制浆表观粘度值。 微波改性实验中，辐射功率为400W时，所制备的煤浆表观粘度最低，为396mPa•s。其原因是，400W前煤内在水分含量高，减少了流动介质作用的水量，造成制备出的精细油水煤浆的粘度高；400W后煤孔结构变大，吸水能力增强，导致颗粒之间的润滑性能减小，制备出的精细油水煤浆的粘度增大。

The coal resources of the east of Junggar coalfield is estimated (390 billion tons) accounted for 17.8% of the total reserves in Xinjiang (2.19 trillion tons), accounting for 7.2% of the national coal reserves (5.56 trillion tons). Coal-based, long-flame coal caking coal and weakly caking coal is the country’s largest integrated coalfield. The coal in Junggar of East coalfield mostly is characterized in low ash and water content, high volatile matter yield, low sulfur, low phosphorus and low chlorine content by, it is an alternative fuel and is suitable for the preparation of ceramic kiln and glass furnace fine COWM. This thesis is mainly base on the research about the east of Junggar’s coal as raw materials, in three different solvent (Tetrahydronaphthalene, N-Methyl pyrrolidone and Diesel) in the swelling experiment, the coal and the solvent ratio of swelling time, temperature, solvent, swelling etc. and derive the swelling kinetic equation. The east of Junggar’s coal as raw materials, with a dry preparation of fine COWM particle size distribution, type of dispersant, the dispersant metering and water, diesel, coal mass ratio and other factors fine COWM viscosity. Complex with different ranks of coal after pulping through research the east of Junggar’s coal investigated the impact of the degree of metamorphism fine COWM viscosity. Finally, researched microwave modified fine COWM, and explored the laws of microwave power and fine COWM viscosity. I got following conclusions: In the swelling experiment, swelling ratio of the N-methyl pyrrolidone system is higher than the swelling ratio of the Tetrahydronaphthalene system. Coal: solvent is 1:6, the swelling rate of each system, the order of size of the degree of swelling is N-Methyl pyrrolidone system> Tetrahydronaphthalene system Diesel system. The swelling time of 6 h, the three systems the degree of swelling, the maximum size of the order of the degree of swelling is: N-Methyl pyrrolidone system> the Diesel system> Tetrahydronaphthalene system. Degree of swelling of the coal in the above solvents, with the elevated temperature increases to 75℃ after the inflection point, N-Methyl pyrrolidone system and Tetrahydronaphthalene system degree of swelling started to decline, a degree of swelling of the coal and diesel system always decreases as the temperature rises. The strong hydrongen bonding of the coal macromolecules is broken by the polar solvent NMP, therefore the degree larger of swelling of the coal. In the swelling mechanism comparative experiments, the experimental temperature is within a range of 20℃~80℃, the temperature has little influence on the degree of swelling, the equilibrium degree of swelling of the coal in diesel approximately 1.139. Adsorption the the swelling method Suuberg swelling Law aligned east coal swelling behavior were analyzed and compared deduced second-order kinetic equation is dx/dt=K(1-AQ_S x)(1-x) for the adsorption swelling method, the activation energy of the kinetic equation is 1.105 kJ/mol. Swelling adsorption method can be a good description of the swelling behavior of pulverized coal. Orthogonal experiment and single factor experiments to optimize the preparation of fine COWM process parameters: dispersant Tween 80 for 1.3 g water 30 g the diesel 35 mL and 42.5 g the east of Junggar’s coal (d50 for 6.26 um pulverized coal and d50 for 35.1 um pulverized coal mass ratio of 8:2). Prepared under optimal conditions, the fine COWM viscosity is 217 mPa•s. COWM concentration is 42.1%, in line with the national coal slurry technical conditions the apparent viscosity of coal slurry below 60℃. In the Blending pulping experiments, with low-rank coals into the overall apparent viscosity than high rank coals. High rank coal blending pulping process, when high-rank coals at 9:1 with into Huangling coal better than Sihe coal, the Sihe coal is superior to the other ratios Huangling coal. With the high degree of metamorphism of coal and low-rank coals, the apparent viscosity values are greater than the value of the pulp and apparent viscosity the east of Junggar’s coal under optimal conditions. In the Microwave modification experiments, when the radiated power is 400W, the preparation of the coal slurry apparent viscosity minimum of 396 mPa•s. The reason is that, 400W former coal inherent moisture content is high, reducing the amount of water flowing medium role, resulting in a high viscosity prepared fine COWM; 400W coal pore structure becomes large, water-absorption capacity enhanced, leading to the lubrication between particles the performance decreases, and slurry viscosity of COWM increases.
