为了研究La0.7 Sr0.3 CoO3-δ钙钛矿催化剂对碳黑的催化氧化过程,本研究通过研究催化剂和碳黑的两种不同接触方式,即紧密接触与松散接触,讨论了其对碳黑催化氧化过程的影响.结果表明,与松散接触和无催化剂接触条件相比,紧密接触条件下碳黑的tig(起燃温度)分别下降了89.5和157.4℃,同时随着催化剂/碳黑的比例增加,碳黑氧化的tig、tm(最大转化温度)、tf(燃净温度)均向低温区域移动,表明该催化剂对碳黑有着良好的催化氧化性能.“,”In order to study the catalytic oxidation process of carbon black over La0.7 Sr0.3 CoO3-δ perovskite catalyst，two different contact modes of the catalyst and carbon black were designed，namely intimate contact and loose contact，and used to observe the reaction behavior. The results showed that the tig (light-off temperature) of carbon black decreased by 89.5 and 157.4℃under intimate contact conditions compared with the loose contact and no catalyst contact conditions. Meanwhile，as the ratio of catalyst/carbon black increased，the tig，tm (maximum conversion temperature) and tf (burn-up temperature) of the carbon black all shifted to the low temperature，indicating that the catalyst had good catalytic performance for carbon black oxidation.
