构造煤甲烷吸附表面能研究
The surface energy of methane adsorption of tectonic coal
摘要
Abstract
The fundamental reason of coal adsorption difference is coal surface energy. In this paper, the effect which is from dynamic metamorphism on tectonic coal structure and components was analyzed. In the process of adsorption of methane, using methane adsorption isotherm experiments, we calculated the surface energy change of primary structure coal and tectonic coal at different temperatures, and causes of surface energy change of tectonic coal were analyzed from the perspective of dynamic metamorphism. The results show that the transformable effect which is from dynamic metamorphism on structure and components of tectonic coal is obvious, the micro pores structure of tectonic coal is more developed than symbiotic primary structure coal, and the tectonic coal has stronger adsorption capacity. The calculation results also show that, both the lower value of surface energy and ad-sorption methane capacity of tectonic coal are .larger than symbiotic primary structure coal with the increase of temperature and pressure.关键词
