Process for the removal of nitrogen compounds from a fluid stream

At lower temperatures an acidic molecular sieve adsorbent preferentially adsorbs water and basic organic nitrogen compounds over weakly basic organic nitrogen compounds such as nitrites. Elevated temperatures improve the capacity of acidic molecular sieve adsorbents to adsorb nitrites in the presence of water.

Integrated desulfurization and denitrification process including mild hydrotreating of aromatic-lean fraction and oxidation of aromatic-rich fraction

Deep desulfurization of hydrocarbon feeds containing undesired organosulfur and organonitrogen compounds to produce a hydrocarbon product having low levels of sulfur-containing and nitrogen-containing compounds, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the refractory organosulfur and organonitrogen compounds and an aromatic-lean fraction containing a substantial amount of the labile organosulfur and organonitrogen compounds. The aromatic-lean fraction is contacted with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized organosulfur and organonitrogen compounds. These oxidized organosulfur and organonitrogen compounds are subsequently removed, producing a stream containing reduced levels of organosulfur and organonitrogen compounds.
