Model fuel desulfurization and denitrogenation using copper and cerium modified mesoporous material (MSU-S) through adsorption process

The application of MSU-S, CeO 2 -MSU-S, and Cu 2 O-MSU-S in desulfurization and denitrogenation of model fuel containing benzothiophene (BT), dibenzothiophene (DBT), quinoline and carbazole were studied in batch and continuous process. The copper-modified MSU-S showed the highest capacity to adsorb...

Description
Summary:The application of MSU-S, CeO 2 -MSU-S, and Cu 2 O-MSU-S in desulfurization and denitrogenation of model fuel containing benzothiophene (BT), dibenzothiophene (DBT), quinoline and carbazole were studied in batch and continuous process. The copper-modified MSU-S showed the highest capacity to adsorb sulfur and nitrogen compounds compared to other adsorbents. The adsorption selectivity of all adsorbents for nitrogen was slightly higher than for sulfur, indicating the selective adsorption of nitrogen over sulfur. The Langmuir model represented better equilibrium data fitting than Freundlich model for carbazole, DBT, and BT adsorption on MSU-S, CeO 2 -MSU-S, and Cu 2 O-MSU-S. It was found that quinoline adsorption data on MSU-S, CeO 2 -MSU-S, and Cu 2 O-MSU-S can be presented by Freundlich model very well. The kinetics of adsorption followed the pseudo-second-order model for all species over each adsorbent. According to the breakthrough curve order, the adsorptive selectivity for the adsorbates increased in the order of DBT
