【摘要】：低氣化反應(yīng)性是制約石油焦氣化利用的重要因素,為探究石油焦高溫催化氣化的可行性,采用下落式固定床氣化反應(yīng)系統(tǒng),結(jié)合SEM-EDS分析技術(shù),詳細(xì)研究了石油焦在高溫條件下的催化氣化行為。結(jié)果表明:在1400℃下,石油焦與褐煤的氣化反應(yīng)性有15倍之差,富含F(xiàn)e、Ca的氧化物和褐煤灰對石油焦的氣化具有明顯的促進(jìn)作用,可將石油焦的氣化反應(yīng)性提高8倍之多,已接近褐煤的氣化反應(yīng)性;氣化溫度高于煤灰的熔融溫度時,未反應(yīng)碳的存在抑制了礦物質(zhì)熔融,為石油焦高溫催化氣化的發(fā)生提供了可能。石油焦與煤共氣化是改善石油焦高溫氣化反應(yīng)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，
