A process is described for the denitrogenation of a feed comprising a nitrogen-containing hydrocarbon compound containing a carbon-nitrogen bond, which comprises: contacting the feed, in the presence of hydrogen, over (i) a bulk iron catalyst which contains at least 50 percent elemental iron, based on the weight of the catalyst, and one or more alkali or alkaline-earth metals, or (ii) an iron catalyst wherein the iron is dispersed upon an inorganic oxide support, the catalyst containing at least about 0.1 percent iron, based on the total weight of the catalyst, the supported metallic component containing at least 50 percent iron, exclusive of the support component, or components, of the catalyst, and one or more alkali or alkaline-earth metals, at a temperature ranging from about 225/sup 0/C to about 430/sup 0/C and hydrogen partial pressure ranging from about 0 psig to about 1000 psig sufficient to cleave the carbon-nitrogen bond of the nitrogen-containing hydrocarbon compound and denitrogenate the nitrogen-containing hydrocarbon compound.
