分别对神华煤和神华煤直接液化残渣的水蒸气和CO_2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;CO_2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CO_2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CO_2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.

The gasification reactivity of Shenhua coal char (CC) and Shenhua coal direct liquefaction residue char (RC) with CO_2 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 CO_2 gasification activity than CC, which is due to different influencing factors for steam and CO_2 gasification. For steam gasification the reactivity of char is mainly affected by coal rank, but for CO_2 gasification the reactivity of char is mainly affected by the catalysis of mineral matter.
