Effect of Carbon Promoters on the Performance of Cu-Zn-Al Catalyst Prepared by Complete Liquid-Phase Technology

doi:10.3724/SP.J.1088.2010.00464

Abstract

Abstract: Cu-Zn-Al slurry catalysts were prepared by a complete liquid-phase technology and characterized by X-ray diffraction, N₂ adsorption, H₂ temperature-programmed reduction, and NH₃ temperature-programmed desorption. The effects of carbon nanotubes and carbon microspheres as promoters on catalyst performance for alcohol synthesis were investigated. The results indicated that the Cu-Zn-Al methanol synthesis catalysts showed activity for the synthesis of higher alcohols and hydrocarbons. Cu⁰ particles with larger grain size were conducive to the growth of carbon chains. Adding carbon microspheres can significantly decrease the size of Cu⁰ particles and improve the selectivity for methanol.

Key words: copper, zinc, aluminum, complete liquid-phase technology, higher alcohol, carbon nanotube, carbon microsphere
