Catalytic performance of Co-Mo-Ce-K/γ-Al

Yuqiong ZHAO, Yongfa ZHANG

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 4,   Pages 457-460 doi: 10.1007/s11705-010-0524-7

Abstract: The catalytic performance of Co-Mo-Ce-K/γ-Al O catalyst for the shift reaction of CO in coke oven gas is investigated using X-ray diffraction (XRD) and temperature-programmed reduction (TPR). The results indicate that Ce and K have a synergistic effect on promoting the catalytic activity, and the Co-Mo-Ce-K/γ-Al O catalyst with 3.0 wt-% CeO and 6.0 wt-% K O exhibits the highest activity. CeO favors Co dispersion and mainly produces an electronic effect. TPR characterization results indicate that the addition of CeO -K O in the Co-Mo-Ce-K/γ-Al O catalyst decreases the reduction temperature of active components, and part of octahedrally coordinated Mo transforms into tetrahedrally coordinated Mo , which has a close relationship with the catalytic activity.
