2、從熱失重、氣體產(chǎn)物和殘余固體特性角度探究了二者在共氣化過程中的相互作用規(guī)律。結(jié)果表明，二者在共氣化過程中存在協(xié)同效應(yīng)；與二者單獨(dú)氣化的加權(quán)平均相比，其氣化反應(yīng)速率加快，產(chǎn)氣熱值和碳轉(zhuǎn)化率增大，燃?xì)馄焚|(zhì)和能源效率得到提高。當(dāng)石油焦質(zhì)量分?jǐn)?shù)由25增至75時，協(xié)同效應(yīng)加強(qiáng)，NaCO。對石油焦氣化的催化效果以及石油焦對NaCO。損失的抑制作用均愈加顯著。當(dāng)石油焦質(zhì)量分?jǐn)?shù)為75時，共氣化殘余固體的熔融現(xiàn)象得以抑制。關(guān)鍵詞：黑液；石油焦；共氣化中圖分類號：TK6文獻(xiàn)標(biāo)識碼：Adoi：10．3969／j．issn．1001-8719．2
