The characterization of zeolite X synthesized from Bintan bauxite using nitrogen physisorption technique that employs the BET, BJH and DFT equations was proposed to improve the understanding of the pore characteristics of zeolite X. The BET, BJH and DFT methods were chosen because the characteristics of the synthesized zeolite were characterized using a scanning electron microscope (SEM) showed a typical morphology for zeolite X and zeolite A crystals and the presence of amorphous phase in small abundance. Evaluation is needed to understand the characteristics of micropore, mesoporous and macropore of zeolite X as a synthesis and the best methods. The data obtained show that the DFT method is the most appropriate and superior model to describe the pore size distribution of synthesized zeolite X.
