A feed comprising a nitrogen-containing hydrocarbon compound, or compound containing a carbon-nitrogen bond, is contacted in the presence of hydrogen over a catalyst comprising elemental iron, preferably a fused iron, and one or more alkali or alkaline-earth metals components (possibly with a Group III metal promoter in addition) at reaction conditions sufficient to cleave said carbon-nitrogen bond and denitrogenate said nitrogen-containing hydrocarbon compound, or compounds. Where the compound is an aromatic heterocyclic nitrogen-containing hydrocarbon, or hydrocarbons, containing at least one aryl carbon-nitrogen bond, or feedstock containing such hydrocarbon, or hydrocarbons, the aryl carbon-nitrogen bond, or bonds, are cleaved without significant hydrogenation of the aromatic ring portion of the molecule.
