Preparation and Adsoparation Denitrication of Nb-SBA-15 Zeolite
Nb-SBA-15 zeolite was synthesized with SBA-15 mesoporous zeolite as a carrier via the wetness impregnation. The sample was characterized by X-ray diffraction, BET analysis, Fourier transform infrared, thermogravimetric-differential analysis and Py infrared spectra, respectively. The
property of adsorptive denitrification of Nb-SBA-15 was evaluated with dodecane quinoline as a simulated oil via the static adsorption experiment in a batch-wise reactor. The results show that Nb-SBA-15 zeolite has a highly ordered two-diemensional hexagonal mesoporous structure and some acidities.
The denitrification rate of Nb-SBA-15 could reach 65.19% at the calcination temperature of 300 and the mass fraction of niobic acid loading of 10%.

- Journal of the Chinese Ceramic Society (JCCS), published in Chinese and in English, is a comprehensive monthly periodical focused on the fields of inorganic and non-metallic materials. The main purpose of the JCCS is to report the latest creative achievements in research, production and design for ceramics, glass, cementing materials, refractory, artificial crystals and other non-metallic materials. JCCS is regarded as an important journal in inorganic and non-metallic materials sciences in China and has been awarded by China Association for Science and Technology. The full-text of papers in JCCS is also published by CNKI (China National Knowledge Infrastructure). JCCS is indexed in EI Compendex, CA( Chemical Abstracts) ,SA and Ж and more than 20 databases.
