| 摘 要： | 分别对神华煤和神华煤直接液化残渣的水蒸气和CO2气化反应性进行了研究。结果表明,水蒸气气化反应中,煤半焦的反应性强于残渣半焦;CO2气化反应中,残渣半焦的反应性强于煤半焦。这主要是影响煤和残渣水蒸气和CO2气化反应性的关键因素不同。水蒸气气化反应受煤化程度的影响较大,而CO2气化反应受煤化程度的影响较小,受矿物质催化作用的影响大。

| Abstract: | The gasification reactivity of Shenhua coal char(CC) and Shenhua coal direct liquefaction residue char(RC) with CO2 and steam was studied using a fixed bed reactor.The results show that CC has a higher steam gasification activity than RC,while RC has a higher CO2 gasification activity than CC,which is due to different influencing factors for steam and CO2 gasification.For steam gasification the reactivity of char is mainly affected by coal rank,but for CO2 gasification the reactivity of char is mainly affec... |
