1) cobalt reducibility
Co还原度
1.
The FTS activity order was found to be: Co 1 5Th/HMS>Co/HMS>Co 1 5Zr/HMS>Co 1 5Mn/HMS>Co 1 5Ce/HMS under the conditions of H 2/CO=2 0, T =463～523 K, p =2 0 MPa, GHSV=500 h -1 , which was owing to the lower cobalt reducibility for Mn promoted Co/HMS and the cobalt oxidation at the beginning of FTS for Zr and Ce promoted Co/HMS despite t.
详细研究了钍、锆、锰及铈助剂对钴质量分数为 15 %的Co/HMS催化剂结构、F T合成CO转化率、CO2 选择性及烃分布的影响 ,结果表明 :钍能适当提高F T合成活性 ,且低温下具有较强的链增长能力 ;锆、锰、铈降低了催化剂CO转化率 ,催化剂加氢能力变强 ,导致低碳烃增加较快 ,汽柴油馏分段减低 ,相应的链增长能力降低 ,并以锰和铈较为明显 ;XRD ,TPR及TG表征表明 :锆和铈可提高催化剂Co还原度 ,但F T合成反应时金属Co易被氧化 ,反应中金属Co量明显减少 ,CO转化率降低 ,并以铈最为显著 ;Th助催化剂Co还原度稍有减低 ,Co分散度高于Co/HMS ,且反应中金属Co较为稳定 ,CO转化率得以提高 ;添加Mn助剂后 ,催化剂难以还原 ,反应中活性相金属Co量较小 ,CO转化率较低 。
2) NO reduction by CO

分别采用聚乙二醇凝胶法、球磨法及浸渍法合成了类钙钛矿型复合氧化物和负载型催化剂,利用XRD、BET、TPD、TPR和XPS等手段对催化剂的物化性能进行表征,考察了它们对CO还原NO反应的催化性能。
3) reduction by carbon monoxide
用CO还原
4) reduction of SO2 by CO
CO 还原 SO2
1.
Direct reduction of SO2 by CO toelemental sulfur not only obtained sulfur but also got rid of re-pollution.
因此研制和开发适合含 O2烟气的直接催化 CO 还原 SO2 为单质硫的催化剂具有重大的实际意义。
5) reduction of Fe_tO by CO
CO还原Fe_tO
