摘要
研究了煤炭在超临界水中氧化的基本规律,实验表明在以超临界水为介质的情况下,煤炭氧化过程产生的溶液冷却减压后产生的气相中无有害气体; 其中所含的硫、氮逐步转化为SO42和N2; 煤炭氧化的程度随温度、H2O2水溶液的浓度增加而加快,反应温度的影响尤其显著.
The oxidation of coal in supercritical water was investigated by using O2 decomposed in situ from H2O2 as the oxidant. The results indicated that the sulfur and nitrogen contained in coal were gradually converted into SO42 and N2 respectively by oxidation in the supercritical water medium. The coal oxidation became faster with higher reaction temperature and higher concentration of H2O2.
