Preparation of a Cu-MCM-41 Adsorbent and Its Desulfurization Performance for Diesel Fuel

Abstract

Abstract: The Cu-MCM-41 adsorbent was synthesized by direct insertion of a metal ion as a precursor. The adsorption performance of the adsorbent for commercial fluid catalytic cracking diesel was investigated at room temperature and 100 ℃, respectively. The sulfur removal efficiency of Cu-MCM-41 was still higher than 84% after 5.5 ml diesel was treated at 100 ℃. This means that thiophene and thiophene derivatives favorably adsorb on Cu active sites by a π-complexation process, and the adsorption of sulfur-containing aromatic compounds over Cu-MCM-41 is highly selective.

Key words: copper, MCM-41 molecular sieve, desulfurization, selective adsorption, diesel, adsorbent
