Research progress on removal of diesel aromatics by adsorption process

The latest developments of commonly used adsorbents,aromatics adsorption mechanisms and main forms and characteristics of aromatics adsorption separation processes were reviewed.The research progress on adsorbents,such as metal oxide adsorbent,carbon material adsorbent,silicon-based mesoporous material adsorbent were summarized.The main adsorption mechanisms includingπ-complexation,π-πinteraction and acid center interaction were concluded and the adsorption processes such as fixed bed,moving bed and simulated moving bed were introduced.It was pointed out that the future development trend was the development of new adsorbents and adsorption processes with high selectivity and easy recovery of aromatics.
