Abstract

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.
