Abstract

The coal of Bayah Formation in Lebak Regency, Indonesia have been subjected to attenuated to X-ray diffraction (XRD), to study their chemical and structural characteristics. X-Ray Diffraction (XRD) has been widely used throughout the world and has high accuracy in identifying the molecular structure of coal. Curve-fitting analysis was employed to characterize coal structural. Based on ASTM, the coal rank from this area is high-volatile bituminous B. The research results show all coals have the similar coal structural crystallite characteristics. The value of d002 is in the range of 3.87 to 3.96, reflecting the coals have a low content of crystalline structure. The crystallite height (Lc) and diameter (La) were increase, while d002 decrease in relation of more mature coals. Due to structural parameters (d002, Lc and La) the coals of Bayah Formation dominantly by disordered amorphous structure, with small amount crystallite structure
