Abstract: The removal of basic nitrogen compounds from model oil (consisting of quinoline and dodecane as solvent) over Rare-earth-metal-based Y molecular sieve as adsorbent in batch-wise reactor. The optimum adsorption temperature was tested and thermodynamics and kinetics of adsorption were investigated. The results showed that the optimum adsorption temperature was 393K，the nitrogen removal can reach 55.8%, and statically saturated adsorption capacity was 23.56 mg/g. The adsorption process over RE/Y zeolite was agreed well with the Langmuir model and pseudo-second-order rate model, and was an endothermic chemisorption which run spontaneously, the activation energy was 11.49 kJ/mol.
