| 摘 要： | 采用硝酸盐浸渍法制备了以La_(0.9)Sr_(0.1)Co_(0.6)Fe_(0.4)O_3为代表的系列CaO载体负载型ABO_3助燃剂,考察了CO催化氧化活性和烧碳速度以及抗硫中毒性。实验结果表明,在实用的高温区性能接近铂系助燃剂,还利用XRD,IR,TPD和TG等手段测定了助燃剂的物相结构和表面程脱性质,探讨了SO_2中毒机理。

| Abstract: | Perovskite promoters were prepared. The CO oxidation and sulfur-resistant property of those promoters were investigated. XRD, TPD, IR and other modern methods were used to study the crystal structure, solid phase, adsorption, and mechanism of SO_2-poisoning. The results show that those promoters have a high activity and a good sulfur-resistant property. It may be used as the promoter in the regeneration of zeolite catalyst, it can speed up the combustion rate of coke and decrease the amount of CO in tail gas. |
