摘要
Abstract
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.关键词
