Abstract

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
