以正己烷为碳源制备碳化钼

Preparation of molybdenum carbide with n-hexane as carbon source

采用程序升温法,以正己烷为碳化原料制备碳化钼,对噻吩加氢脱硫活性进行了评价。通过X射线衍射分析、X射线光电子能谱分析、比表面测定等方法对试样进行了表征。结果表明,在正己烷/氢气(摩尔比)为0.006,反应温度为600℃的条件下,反应具有较好的碳化效果。

Molybdenum carbide was prepared with n-hexane as carbon source by temperature programming method.The samples structure was characterized by X-ray diffraction(analysis,)X-ray photoelectron spectroscopy and BET specific area measurement,and the catalytic performances of the sampales were evaluated by thiophene hydrodesulfurization test.The results showed that a good carbonization effects could obtained under the reaction condition of n(n-hexane)/n(H_2) 0.006 and temperature 600()℃.
