【摘要】：低气化反应性是制约石油焦气化利用的重要因素,为探究石油焦高温催化气化的可行性,采用下落式固定床气化反应系统,结合SEM-EDS分析技术,详细研究了石油焦在高温条件下的催化气化行为。结果表明:在1400℃下,石油焦与褐煤的气化反应性有15倍之差,富含Fe、Ca的氧化物和褐煤灰对石油焦的气化具有明显的促进作用,可将石油焦的气化反应性提高8倍之多,已接近褐煤的气化反应性;气化温度高于煤灰的熔融温度时,未反应碳的存在抑制了矿物质熔融,为石油焦高温催化气化的发生提供了可能。石油焦与煤共气化是改善石油焦高温气化反应性的有效方法。
[Abstract]:Low gasification reactivity is an important factor restricting the utilization of petroleum coke gasification. In order to explore the feasibility of high temperature catalytic gasification of petroleum coke, a falling fixed-bed gasification reaction system was adopted, combined with SEM-EDS analysis technology. The catalytic gasification behavior of petroleum coke at high temperature was studied in detail. The results showed that the gasification reactivity of petroleum coke and lignite was 15 times greater than that of lignite at 1400 鈩，
