Investigation of selective denitrogenation of liquid fuel with different MIL-101 adsorbents
In this work, three new structures of MIL-101 with a base metal of chromium (Cr), vanadium (V), and manganese (Mn) have been synthesized to improve selective adsorbing quinoline (QUI) from a liquid fuel. Different characterization tests were used to identify the specifications of the synthesized adsorbents; namely Brunauer–Emmett–Teller (BET), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and temperature-programmed desorption (TPD). Studies indicated that pseudo-first order and Langmuir isotherm are accurate and suitable models for determining kinetic and equilibrium data of QUI adsorption on these adsorbents. Based on the results, MIL-101 (Mn) had the highest maximum adsorption capacity of 70.08 (mg N · g−1 ads.) in comparison to MIL-101 (Cr) and MIL-101 (V). For different adsorbents, the QUI/dibenzothiophene (DBT) selectivity was investigated by measuring of the adsorption of these components from their mixture. Finally, the QUI/DBT selectivity was in the following order of MIL-101 (Mn) > MIL-101 (V) > MIL-101 (Cr). Density functional theory (DFT) simulation was used to validate experimental results. Calculated bonding energies ratio for QUI and DBT indicated that MIL-101 (Mn) is the most selective adsorbent.
期刊介绍：
The Canadian Journal of Chemical Engineering (CJChE) publishes original research articles, new theoretical interpretation or experimental findings and critical reviews in the science or industrial practice of chemical and biochemical processes. Preference is given to papers having a clearly indicated scope and applicability in any of the following areas: Fluid mechanics, heat and mass transfer, multiphase flows, separations processes, thermodynamics, process systems engineering, reactors and reaction kinetics, catalysis, interfacial phenomena, electrochemical phenomena, bioengineering, minerals processing and natural products and environmental and energy engineering. Papers that merely describe or present a conventional or routine analysis of existing processes will not be considered.
