Abstract: The isomerization of nhexane over Mo 2C /Mo O2 - Z r O2 catalyst was investigated. First, the precursor solid superacid Mo O3 - Z r O2 was prepared by coprecipitation process, using the mixture of cetyltrimethylammonium bromide and polyethylene glycol 20000 as templates. It can be seen that the precursor samples had applicable surface area, pore diameter and volume from the BET and FTIR characterization of the Mo2C/MoO2ZrO2.The total acid of precursor Mo O3 - Z r O2had a large decline after carbonized. The conversion and selectivity of Mo2C/MZP0.005C0.5 are much more than single auxiliary catalystafter adding catalyst mixed assistant. The conversion rate and selectivity reached 67.5%, 75.2%, respectively.

摘要： 研究了 Mo 2C /Mo O2 - Z r O2 催化剂上正己烷的异构化反应。分别以十六烷基三甲基溴化铵和聚乙二醇2 0 0 0 0为模板剂, 采用共沉淀法制备前驱体固体超强酸 Mo O3 - Z r O2, 从前驱体 Mo O3 - Z r O2 的B E T和F T I R表征可以看出, 所得样品具有适宜比表面积、 孔径和孔容。前驱体 Mo O3 - Z r O2经碳化后总酸量大幅度的下降。加入混合助剂的 Mo 2C /MZ - P 0. 0 0 5 - C 0. 5的催化剂无论转化率和选择性都要比加入单一助剂的催化剂要高得多, 其转化率达 6 7. 5%, 选择性7 5. 2%。
