| 摘 要： | 用浸渍法制备过渡金属氧化物担载型催化剂MOx/USY(M=Co、Mo、Co-Mo),用热重红外联用技术考察了MOx/USY催化剂对黄土庙(HTM)煤热解失重特性和热解产物生成规律的影响。热重实验结果表明,MOx/USY催化剂可使HTM煤热解的二次脱气条件更为温和,热解峰温分别提前14、23和9℃。动力学分析结果表明,MOx/USY催化剂可降低HTM煤样热解的活化能。FT-IR研究表明,MOx/USY催化剂可有效改善HTM煤热解产物的组成和分布,CoOx/USY催化剂能显著提高HTM煤热解产物中高热值气体(CO、CH4)和轻质芳烃以及脂肪烃类化合物的含量;MoOx/USY催化剂没有明显改善HTM煤热解产物组成和分布;MoOx-CoOx/USY催化剂可促进CO、CH4、轻质芳烃和脂肪烃类化合物的生成,却使热解产物的生成向高温区移动,说明USY负载的不同过渡金属氧化物对煤样热解行为和热解产物有较大影响。

| Abstract: | MOx/USY catalysts (M=Co,Mo,Co-Mo) were prepared by incipient wetness impregnation method. Catalytic pyrolysis of Huang Tu Miao (HTM) coal was investigated and the pyrolysis products were examined by TG-FTIR technique. TG results indicate that MOx/USY catalysts are effective in lowering degasifiction temperature (14, 23 and 9℃ respectively) in HTM coal pyrolysis. Kinetic calculations show that MOx/USY catalysts are effective in lowing activation energy of pyrolysis. FT-IR analyses show that the MOx/USY catalysts are effective in manipulating coal pyrolysis products. CoOx/USY catalyst promote the generation of CH4, CO and aromatic hydrocarbons and aliphatic hydrocarbons in HTM coal pyrolysis. MoOx/USY catalyst show little effect in manipulating pyrolysis products. CoOx-MoOx/USY catalyst is a promising catalyst in giving high yield of volatile products, however the pyrolysis temperature moved to high temperature region. These results indicate that different metal oxides incorporated zeolite USY have different impact on manipulating pyrolysis products. |
