Abstract: The heterocyclic nitrogen compounds containing in liquid hydrocarbons streams poison many industrial catalysts. The selective removal of the nitrogen species from refinery streams by adsorption at ambient temperature is a promising approach. Remarkable adsorption capacity and selectivity towards heterocyclic nitrogen compounds were observed for metal-organic framework [Cr3O(C8H4O4)3F(H2O)2] (MIL-101) under the sorption from isooctane and the hydrotreated gas oil. The adsorption capacity of MIL-101 towards heterocyclic nitrogen compounds is significantly higher than the capacity of conventional adsorbents such as activated carbons, activated alumina, silica-based adsorbents and zeolite-based materials especially under the sorption from hydrocarbon with low nitrogen content. The spent MIL-101 can be regenerated and reused in the next adsorption cycle without loss of its adsorption capability. The very high adsorption capacity and selectivity of metal-organic framework MIL-101 for the nitrogen compounds, along with its good regenerability, indicate that MIL-101 may be the promising adsorbent for deep denitrogenation of liquid hydrocarbon streams.
