摘要
选用鸡西褐煤 ,在 1 80～ 2 4 0℃下 ,于氢氧化钠和水溶液中用氧气氧化 ,考察了碱煤比、反应温度、氧初压、反应时间及水量对芳香羧酸产率的影响。实验结果表明 。
Jixi lignite was oxidized by alkali oxygen in water solution of NaOH under temperature range of 180—240℃. Observed was the influence on yield of aromatic carboxylic acid by parameters as alkali/lignite ratio, reaction temperature, initial oxygen pressure, reaction time and water quantity. Experiment results denoted that main effective factors on acid yield were alkali/lignite ratio and initial oxygen pressure.
