Under basic conditions

Al-containing mesoporous zeolite Al-MCM-41 was successfully synthesized by hydrothermal synthesis method using sodium metasilicate as silica source

sodium aluminate as alumina source and CTAB as templating agents. XRD and BET were used to investigate the characterization of Al-MCM-41. The adsorptive capacity of this mesoporous zeolite for quinolone was analyzed through adsorption experiment for the nitrogen compounds in diesel in a continuous fixed bed reactor. The thermodynamic performance of the adsorption process was investigated in the range from 353.15 K to 393.15 K. Langmuir and Freundlich isothermal adsorption models were employed to fit the experimental data. The results of characterization showed that Al-MCM-41 with Si/Al 60 had larger pore volume

specific surface area and narrow pore distribution. The mesoporous molecular sieve had good crystallization degree and ordered pore structure. The adsorption of quinoline on zeolite Al-MCM-41 with Si/Al 60 was in accordance with the Freundlich isothermal adsorption model. The thermodynamic parameters

such as ΔH

ΔG

ΔS and apparent activation energy

were calculated to be -0.7682 kJ·mol-1

-28.1215 kJ·mol-1

73.2434 J·mol-1·K-1 and 2.8575 kJ·mol-1

respectively. Pesto-second order rate equation was better to describe adsorption of quinolone.
