纸浆黑液为催化剂的高变质无烟煤水蒸气催化气化的热重与在线质谱研究

Study on Black Liquor Catalytic Gasification of High Metamorphosed Anthracites with Steam in Thermogravity and Online Mass Spectrometry

以纸浆黑液为催化剂,用热天平的等温法研究高变质无烟煤常压纯水蒸气催化气化反应。通过热重曲线和在线质谱分析解释纸浆黑液催化气化机理;为扣除纸浆黑液中固形物对气化过程的影响,对纸浆黑液和以纸浆黑液为催化剂的无烟煤进行等温实验,通过在线质谱确定了升温段热解与恒温段气化的产物,并得出了消除纸浆黑液影响的煤转化率的计算公式。

Using black liquor of paper pulp plant as catalyst, the steam gasification of high metamorphosed anthracites was investigated by isothermal thermo-gravimetric analysis under ambient pressure. The black liquor catalytic gasification mechanism was explained by thermogravity curves and online mass spectrometry. To eliminate the influence of solid in black liquor on the gasification process, the gasification of black liquor and anthracites catalyzed by black liquor were investigated by isothermal thermo-gravimetric analysis. The gasification products of increasing temperature and isothermal stage were determined by online mass spectrometer. The coal conversion eliminating the influence of solids in black liquor was obtained.
