The feasibility Of using microporous and mesoporous materials as adsorbents to remove nitrogen-containing compounds (NCCs) in fuel, such as pyridine, quinoline, pyrrole, and indole, was explored. A mesoporous molecular sieve Ti-HMS was chosen as the optimum adsorbent for the adsorptive denitrogenation (ADN) of fuel. Effect of adsorption time, temperature, and ratio of adsorbent to on (A/O) on the removal of NCCs was investigated. Meanwhile, the adsorption isotherms and adsorption thermodynamics were Studied. The thermodynamic Functions show that the adsorption of NCCs oil Ti-HMS is ail exothermic, irregularity decreased, spontaneous physical process. Furthermore, the adsorption process primarily Occurs ill the pores of Ti-HMS, which is confirmed by comparing the adsorptive denitrogenation performance of Ti-HMS with uncalcined Ti-HMS.
