| 摘 要： | 在热天平中采用等温热重法对石油焦、稻草焦、石油焦/稻草混合物以及石油焦/稻草焦混合物进行了CO2共气化研究,实验温度900~1 050 ℃,添加稻草焦的质量比为0~0.5,考察稻草焦对石油焦的催化气化作用。结果表明,在一定气化温度下,石油焦和稻草焦混合物的共气化碳转化率高于各自气化碳转化率的简单加和,具有一定的协同效应,混合物的气化反应速率随着稻草焦添加比例的增加而升高。石油焦、稻草、稻草焦及其各个混合物的反应活性由大到小的顺序为:稻草半焦>脱灰稻草半焦>石油焦/稻草混合物>石油焦/稻草焦混合物>石油焦/脱灰稻草混合物>石油焦/脱灰稻草半焦混合物>石油焦。

| Abstract: | A thermogravimetric apparatus(TGA)was used to investigate the CO2-char gasification characteristics of petroleum coke,straw char,and the mixture using isothermal mode at the temperature ranging from 900 ℃ to 1 050 ℃.The rate of co-gasification increases with an increase of straw addition ratio.The results show that the order of reactivity of various prepared chars is as follows:straw char>deashing straw char>the mixture of petroleum coke and straw> the mixture of petroleum coke and straw char>the mixture of petroleum coke and deashing straw>the mixture of petroleum coke and deashing straw coke>petroleum coke.The co-gasification rate of the mixture of petroleum coke and straw char is higher than the rate sum of single petroleum coke and single straw,suggesting that there is a synergistic effect due to the co-gasification. |
