煤中矿物质对神府煤快速液化的影响

Study the effect of mineral matter on Shenfu coal rapid liqufaction

利用共振搅拌反应器研究了煤中矿物质对神府煤高温快速液化的影响。原料煤经酸洗去除煤中大部分矿物质,脱灰率可达84·83%。脱灰后的煤在490℃进行加氢液化,结果表明,煤中矿物质的降低对神府煤高温快速液化有较大的影响,尤其影响了煤的初始高活性,煤转化率及液化产物的产率都降低,且煤中矿物质的降低会使矿物质自催化作用减弱,影响了神府煤液化产物质量。

The effect of mineral matters on the process of shenfu coal rapid liquefaction was studied by using resonance agitation reactor. The mineral matters of coal were removed by acid washing, the removing rate was 84. 83%. The reaction process of quickly liquefying of the dimineralized coal was studied at 490℃. The results showed that, the coal conversion and benzene soluble yield decline obviously. The mineral matter of coal affects shenfu coal quick liquefaction, especially for the initial high stage. And dimineralization results in weakening of the mineral matters autocatalysis effect.
