The The denitrogenation of nitrogen-containing hydrocarbon feedstocks, or removal of nitrogen from nitrogen compounds, requires hydrogenation of the nitrogen compounds. The reaction proceeds rapidly with lower boiling feedstocks, but becomes much slower as the boiling range of the feedstock increases. With high boiling range feedstocks, e.g., heavy vacuum gas oils and residua, denitrogenation becomes more difficult, and complete denitrogenation is not obtained even in high severity reactions with the best of presently commercially available catalysts. Hydrodenitrogenation processes require greater consumption of hydrogen as the severity of the process conditions is increased.denitrogenation of nitrogen-containing hydrocarbon feedstocks, or removal of nitrogen from nitrogen compounds, requires hydrogenation of the nitrogen compounds.
