摘要
采用干法制备得到氟氧化铝,NH3-TPD法对其进行酸性表征,并作乙醇脱水催化活性测试。结果表明:制备得到的氟氧化铝酸强度比纯AlF3有了较大的提高,催化乙醇制乙烯的最高转化率和选择性为96.65%和99.43%。
The Fluorinated Alumina samples were prepared by dry method.From the characterization of acidity by NH3-TPD and the catalysis test results,the acid strength was enhanced and the conversion rate of Ethanol could reach to 96.65%.the selectivity of Ethanol to Ethylene was up to 99.43%.
