摘要
对神府大柳塔烟煤及其300、400、550、700℃干馏产物,在75gKOH/30g试样(ad.)水溶液、氧初压为5.5MPa或6.0MPa和250℃的条件下氧化2h,其氧化产物水溶酸的产率及其组成随干馏温度的升高而变化,在干馏温度为400℃时水溶酸的产率达到最大(54.96%对daf.试样),并采用气相色谱法进行定性、定量分析。
Shenfu Daliuta bituminous coal and its carbonized products at 300, 400, 550 and 700℃ were subjected to alkalioxygen oxidation at 250℃ in an aqueous solution of potassium hydroxide (75g KOH/30g samples (ad )) for 2h The yields and compositions of watersoluble acids changed with increacing carbonization temperature At carbonization temperature of 400℃, a maximum yield (54 9%, to daf samples) of watersoluble acid was reached The oxidation products were aoalyzed qualitatively and quantitatively by gas chromatograghy
