摘要： 在工业装置上，以水-乙醇为浸渍液溶剂制备长链烷烃脱氢催化剂，考察了溶剂中乙醇的作用。以N2吸附-脱附、X射线衍射、CO脉冲化学吸附、H2-程序升温还原、热重分析等方法对催化剂进行了表征，并在固定床反应器上对催化剂性能进行了评价。结果表明，以无乙醇添加精制水作浸渍液溶剂制备的长链烷烃脱氢催化剂具有较高的Pt分散性、脱氢活性及较好的活性稳定性。

Abstract: The long-chain alkane dehydrogenation catalyst was prepared with water-ethanol as solvent in an industrial plant, and the effect of ethanol in the solvent was investigated. The catalysts were characterized by N2 adsorption-desorption, X-ray diffraction, CO pulse chemisorptions, H2-temperature programmed reduction and thermogravimetric analysis, and the performance of the catalyst was evaluated in a fixed bed reactor. The results showed that the catalysts prepared by ethanol-free solvent impregnation method had high Pt dispersion, dehydrogenation activity and good activity stability.
Key words: long-chain alkane dehydrogenation, catalyst, digging solution, ethanol, platinum dispersion, dehydrogenation performance
