The Research and Application on CO Adsorption Experiment of Different Metamorphic Coal under the Constant Temperature and Pressure

The purpose of this paper is to find the relationship between coal metamorphic and adsorption of Carbon Monoxide(CO) and reveal the source of CO in mines. Through preparation and industrial analysis of coal samples, mercury injection experiment and analysis of different metamorphic grade coal samples, to analysis the impaction on coal metamorphic grade of CO adsorption. Research shows with the increase of coal metamorphic grade, coal adsorption quantity of CO has a trend that increase at first and then decrease. The conclusion of this paper is that coal adsorption quantity of CO has a positive correlation with the sum of microporous coal samples and pore volume of coal samples and it is helpful to reveal the source of CO in mines.
