Zeolite SSZ-13 was synthesized by a traditional hydrothermal method, and characterized by powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The porous structure of the samples was determined from nitrogen uptake measurements at 77 K, and the surface properties were analyzed by Fourier transform infrared spectroscopy. The zeolite SSZ-13 had a type I isotherm with a uniform pore-size distribution and most pores were less than 1 nm. The Langmuir surface area was 703 m(2)/g. The adsorption of various gases on SSZ-13 was studied experimentally and a high selectivity for CO2 over N-2 was achieved.
