Denitrification and desulfurization integration process, including the oxidation of aromatic-rich fraction and hydrotreating mild aromatic lean fraction

摘要

To produce a hydrocarbon product having a nitrogen-containing compounds and sulfur-containing low-level, the first deep desulfurization of a hydrocarbon feed comprising organic nitrogen compounds and organic sulfur undesirable, difficult to process substantial amounts of In order to separate the aromatic-rich fraction containing an organic nitrogen compounds and gender organic sulfur, aromatics-lean fraction containing an organic nitrogen compounds and organic sulfur unstable a substantial amount of feed to the extraction area I provide a whole. The aromatic-lean fraction, for conversion to organic nitrogen compounds and organic sulfur unstable, while operating under mild conditions, is contacted with the hydrotreating catalyst in a hydrotreating reaction zone. Aromatic rich fraction, is oxidized to convert the organic nitrogen compounds and hard to work into organic sulfur and organic nitrogen compounds oxidized organic sulfur. Organic nitrogen compounds and organic sulfur is oxidized these produces a stream containing an organic nitrogen compounds and organic sulfur levels are substantially removed, are reduced.
