Preparation of Al2O3–ZrO2 Composite Carrier Catalyst and Its Application in the Dehydrogenation Reaction of 2-Butanol

In this paper, the catalysts of copper and zinc components supported on Al2O3–ZrO2 composite carriers were prepared by co-precipitation method. The catalytic performance of the catalysts in the dehydrogenation reaction of 2-butanol was tested. The effects of Al/Zr ratio on the catalytic performance were investigated. The catalysts were characterized by EDS-mapping, XRD, and H2-TPR. The results showed that the addition of an appropriate amount of zirconium component to CuO–ZnO–Al2O3 catalyst helped to disperse CuO species, lower its reduction temperature and improve its reduction characteristics. At 260°C and H2 : N2 = 8 : 95 (v/v), the conversion of 2-butanol could reach 95
