英文摘要: A series of gold zinc oxide catalysts were prepared using a coprecipitation procedure, and their performance for catalytic oxidation removal of CO from H-2 rich gas was investigated in a fixed bed reactor. The results showed that its optimum content of Au was 1.5 wt.% in ZnO, Au(1.5)/ZnO. The effect of calcining temperatures on Au(1.5)/ZnO performance for removal of CO showed that the ideal calcining. temperature was 300 degreesC, Au(1.5)/ZnO-300. During 500 h continuous experimental investigation for Au(1.5)/ZnO-300 to remove CO selectively at 80 degreesC, its performance was slightly decreased when the time on stream was over 350 h. When small amounts of platinum were added to Au(1.5)/ZnO-300, its stability was improved. However, when the content of platinum in Au(1.5)/ZnO-300 was over 1.0 wt.%, the selectivity for removal of CO for Au(1.5)-Pt/ZnO-300 was lowered with increasing content of Pt. The ideal composition for Au(1.5)-Pt/ZnO-300 was 1.0 wt.% Pt, Au(1.5)-Pt(1.0)/ZnO-300. (C) 2002 Elsevier Science Ltd. All rights reserved.
