Regarding environmental effects of NOx emission and negative effects of nitrogen containing compounds (NCCs) on the performance of hydrogen desulfurization (HDS) process, adsorptive denitrogenization (ADN) before HDS process is very important. Metal organic frameworks (MOFs) are a new adsorbent group, which is highly studied for AND process. The goal of this paper is to compare quinolone (QUI) adsorption capacity and QUI/ dibenzothiophene (DBT) selectivity on the OPA-1 and OPA-2 adsorbents (based on the MIL-100 and MIL-101, respectively). These adsorbents were characterized by XRD, FTIR and specific surface area (BET). Isotherm and kinetic studies indicated that the Langmuir isotherm and pseudo-first-order model can successfully describe the experimental data. Among the studied adsorbents, OPA-2 with maximum adsorption capacity equal 91.49 mgN/gads and QUI/DBT selectivity equal 24.56 had the best performance for QUI selective adsorption. The adsorption capacity and selectivity for removal NCCs from industrial sample were 14.65 mgN/gads and 17.69, respectively.
