Adaption of Theoretical Adsorption Model on Coal: Physical Structure

With the motivation to investigate role of coal physical structure on adsorption performance reservoir, 18 different types samples with structures were collected from six profiles four production mines located at China. The characteristics CH 4 examined, and then experimental results fitted analyzed by Langmuir model potential (D-R D-A). prominent factors in terms capacity its adaptability discussed. Results indicate following: a) under condition a similar rank, is governed rock composition heat, effect structural deformation not obvious; b) has certain structures, while D-R evidently suitable describe scaly coal, part broken small vitrinite content; c) D-A high various types, stronger is, higher accuracy is.
