摘要：CO2 gasification of petroleum coke using black liquor as a catalyst was performed in a thermogravimetric analyzer (TGA) under temperatures 1223-1673 K at ambient pressure to evaluate the effect of black liquor loading on petroleum coke gasification. It was found that the gasification reactivity of petroleum coke was improved greatly by black liquor. The gasification reactivity was affected by different loading methods in the order: wet grinding > dry grinding > physical impregnation > dry mix. The catalytic activity of black liquor was higher than that of pure alkali metal. The effect of temperature on the gasification reactivity of petroleum coke was changed by black liquor. The reactivity reaches its maximum at 1573 K. The reactivity of petroleum coke was found higher than that of Shenfu coal when black liquor loading is 5 wt.% (of petroleum coke), clearly demonstrating that black liquor could be an effective catalyst for petroleum coke gasification.
