Two-Stage Sequential Adsorption System for Denitrogenation and Desulfurization of Model Diesel Oil over Ion-Exchanged Y Zeolites

Abstract: This work focused on adsorptive desulfurization (ADS) and denitrogenation (ADN) in single-and two-stage systems. Na-Y zeolite possessed the best 4,6-DMDBT and DBT adsorption performances. La-Y zeolite exhibited the best ADN efficiency. The impact of nitrogen compounds and aromatics on ADS capacity and the impact of sulfur compounds and aromatics on ADN ability over ion-exchanged Y zeolite were evaluated in the single-stage system. The nitrogen compounds not only have the ability to compete, but they also have … Show more

“…Several types of adsorbents have been reported for ADN of liquid hydrocarbon fuels, including zeolite, activated carbon (AC), activated alumina, clay, silica gel, metal–organic frameworks (MOFs), and polymers. , Among them, AC is a promising adsorbent for ADN due to its high specific surface area, easy modification of its surface chemistry, and wide source for preparation . These types of porous materials have shown higher adsorptive capacity and selectivity for nitrogen compounds. , …”
