Abstract

Ozone may be used to accelerate the oxidation of coal and hence to permit more rapid determination of its susceptibility to self-heating and self-ignition. In the present research, the coal is oxidized at 25°C, with low ozone concentrations (~10 mg/L), so as to moderate the destructive effect of secondary oxidative processes. The influence of the size and specific surface of the coal particles on the reactivity with ozone is assessed.

粒度对有限变质发育煤臭氧氧化的影响

摘要

臭氧可用于加速煤的氧化，因此可以更快速地确定其对自热和自燃的敏感性。在目前的研究中，煤在 25°C 时被氧化，臭氧浓度低（~10 mg/L），以减轻二次氧化过程的破坏作用。评估了煤颗粒的尺寸和比表面积对与臭氧的反应性的影响。
