    • 摘要: 采用热重分析发研究了神府煤及其催化热解动力学,用Kissinger模型和Ozawa模型对神府煤三种情况下(SFC,10%-Mo/A12O_(3)-SiO_(2)和10%-Mo/3%-P-A12O_(3)-SiO_(2))进行动力学研究。Kissinger法计算得出3种情况的活化能分别为280.5 kJ/mol,254.9 kJ/mol,254.6 kJ/mol;Ozawa法为278.0 kJ/mol,253.8 kJ/mol,253.6 kJ/mol。在一定程度上解释了催化剂的活化功能,提高了焦油产率。同时根据催化剂的结构特征初步解释了可能的催化机理,为深入研究煤炭的资源化利用提供了参考。

    • 摘要: 为了降低神府煤的自燃危险性,采用原位共沉淀法制备了锌镁铝水滑石粉状复合阻化剂,将其与神府矿区长焰煤种按比例进行机械混合制成阻化煤样.利用热重/差示扫描量热仪-傅里叶变换红外光谱仪联用技术对阻化煤样进行分析表明,热重(TG)曲线各特征温度点比原煤总体上滞后,煤着火点提高,阻化剂混合量达到煤样的20%时,滞后现象明显,放热峰温度从135°C升高到560°C,峰面积明显降低,说明锌镁铝水滑石粉状复合阻化剂多级吸热抑制了煤氧化.傅里叶变换红外光谱(FTIR)图谱显示,加入阻化剂煤样CO释放量明显减少,因此锌镁铝水滑石粉状复合阻化剂对神府煤的阻化效果明显.%In order to reduce the spontaneous combustion danger of Shenfu Coal,an in situ coprecipitation method was applied to prepare ZnMgA1-CO3-LDHs complex inhibitor.Then the inhibitor and a given percentage of the long flame coal from Shenfu Mining Area would be mechanically mixed to prepare the inhibition coal samples.A thermogravimetry/differential scanning calorimeter-Fourier transform infrared spectrometer combined technology were applied to analyze the inhibition coal samples.The analysis results showed that each feature temperature point of inhibition coal samples would be delay generally than the raw coal and the ignition point of the coal was increased on the TG curve.When the mixing quantity of the inhibitor reached to 20% of the coal sample,the delay phenomenon would be obvious.The cxothcrm temperature would be increased from 135 °C to 560 °C and the peak area would be obviously reduced.Therefore,the ZnMgAl-CO3-LDHs complex inhibitor could absorb the heat in multi grade and could control the coal oxidation.The FTIR spectra showed that CO released volume from the coal samples added with the complex inhibitor would be reduced obviously,therefore,the complex inhibitor would have an obvious inhibition effect to Shenfu Coal.

    • 摘要: Taking Shenfu coal as the research object,the experiment studied the effects of different activation temperature on the performance of coal-based carbon adsorption materials prepared from Shenfu coal and hydrogen co-generation.In addition,the study was made on the adsorption abilitY,morphological property and gaseous product composition of carbon adsorption materials made from Shenfu coal vitrinite of different enrichment ratios under the activation temperature of 7 00 °C.The results showed that,with the increase of activation temperature,the adsorption value of carbon material would first increase and then decrease.Under the activation temperature of 700 °C,it was found that the adsorptive property of carbon material was good.During the activation process of Shenfu coal vitrinite,at the activation temperature of 700 °C,the content of co-generated hydrogen would increase with the increase of the enrichment ratio of the vitrinite.%以神府煤为研究对象,通过实验考察不同活化温度对神府煤制备炭吸附材料性能和联产氢气的影响,并研究了在活化温度为700°C时,不同富集率的神府煤镜质组所制备的炭吸附材料吸附性能、形貌特征及气相产物成分.结果表明,随着活化温度的升高,神府原煤制备的炭吸附材料的吸附性能先增大后减小,活化温度为700°C时,制备出的炭吸附材料吸附性能较好;神府煤镜质组活化过程中,活化温度为700°C时,联产氢气含量随着镜质组富集率的增大而增大.

    • 摘要: 利用两段式固定床反应装置,研究了神府煤热解-活化耦合产物的特性,探讨了热解温度及活化剂(H2O(g)、CO2和H2O(g)/CO2)对产物性能的影响,揭示了热解-活化耦合反应机制.结果表明,热解温度对半焦的CO2化学反应性影响较小;采用热解-活化两段耦合工艺,可使神府煤热解的焦油产率明显提高,产率最高为17.8%;不同活化剂对两段耦合过程产生的混合煤气(mixture coal gases,MCG)和焦油产率影响为H2O(g)>H2O(g)/CO2>CO2,其焦油组分均以饱和分和芳香分为主;采用H2O(g)/CO2(1∶1)活化剂,可有效提高活性炭的比表面积,其BET比表面积为845.37 m2/g.热解-活化耦合机制主要为活化段产生的合成气(synthesis gases,SG)为热解段煤的加氢热解提供了氢源,丰富的氢自由基促进了煤的加氢热解反应,改变了耦合过程的产物分布和特性.

    • 摘要: 采用傅里叶变换衰减全反射红外光谱法(ATR-FTIR)研究了分散剂官能团特征与神府煤(SFC)成浆性匹配规律。基于4种分散剂的ATR-FTIR分析结果,采用Gaussian分峰法计算了这些分散剂中亲水基团( OH、C O、 C O、3SO−)和疏水基团( CH3、 CH2、 C C)的分布,研究了分散剂中亲、疏水基团对神府煤成浆性的影响。结果表明:用ZFZ分散剂所制备的神府水煤浆(SFCWS)的定黏浓度最高,用MZS分散剂制备的SFCWS的浓度最低。这主要归因于ZFZ分散剂有较多的亲水基团,相对较少的疏水基团,与神府煤有良好匹配性。采用偏最小二乘法(PLS)建立了分散剂与神府煤定黏浓度预测模型和匹配度模型,选用 JJN、DNC和SMS分散剂验证了模型的精确性,误差在±1%以内,同时定黏浓度预测值和匹配度的预测值与定黏浓度的实验值变化趋势一致。%The matching rules between dispersants and Shenfu coals (SFC) slurriability were investigated by using attenuated total internal reflectance Fourier transform infrared spectroscopy (ATR-FTIR). Based on the ATR-FTIR results of four kinds of dispersants, the hydrophilic groups (OH,CO,CO, 3SO−) and hydrophobic groups (CH3,CH2,CC) were calculated by Gaussian peak separation method, respectively, and the effects of hydrophilic and hydrophobic groups on the SFC slurriability were also discussed. The results showed that the slurry concentration of Shenfu coal water slurry (SFCWS) with ZFZ dispersants was the highest, but with MZS dispersants it was the lowest. The results indicated that ZFZ was a good kind of dispersant for SFCWS because of its less hydrophobic groups and more hydrophilic groups. A slurry concentration prediction model and matching degree model between the dispersants and SFC were further proposed by partial least squares method. The models were proved by using JJN, DNC and SMS dispersants with the errors of predictive slurry concentration within±1%. The change trend of predictive slurry concentration and matching degree was consistent with the actual slurry concentration.
