Abstract
A process wherein a feed comprising a nitrogen-containing hydrocarbon compound, or compound containing a carbon-nitrogen bond, is contacted in the presence of hydrogen over an iron catalyst at reaction conditions sufficient to cleave said carbon-nitrogen bond and denitrogenate said nitrogen-containing hydrocarbon compound, or compounds. An aromatic heterocyclic nitrogen-containing hydrocarbon, or hydrocarbons, containing at least one aryl carbon-nitrogen bond, or feedstock containing such hydrocarbon, or hydrocarbons, is contacted with hydrogen, preferably over a fused iron catalyst, at reaction conditions sufficient to cleave the aryl carbon-nitrogen bond, or bonds, without significant hydrogenation of the aromatic ring portion of the molecule. The aryl carbon-nitrogen bond, or bonds, are cleaved, and the cleavage site, or sites, healed with hydrogen, without saturation of the aromatic ring portion of the molecule to which the nitrogen atom of the parent compound was bonded.
