Abstract: Disclosed is a method for hydrogenating a dinitrile to form a diamine. Also disclosed is a method for preparing a catalyst for this hydrogenation reaction by reducing iron oxide with hydrogen. The catalyst ages during the course of making the diamine. An aged catalyst is partially reactivated by interrupting the flow of dinitrile and ammonia feed to a reactor, while maintaining a flow of hydrogen to the reactor.

Abstract: Disclosed is a method for hydrogenating a dinitrile to form a diamine in the presence of ammonia. A liquid stream including a dinitrile is used to scrub a vapor stream including hydrogen and ammonia. Ammonia is taken up in the liquid effluent from the scrubbing treatment. This liquid effluent stream and the hydrogen-rich scrubbed vapors are recycled to the hydrogenation reaction for converting dinitrile to diamine.

Abstract: Disclosed is a method for hydrogenating a dinitrile to form a diamine. Also disclosed is a method for preparing a catalyst for this hydrogenation reaction by reducing iron oxide with hydrogen. Heat in a fluid stream involved in the refinement of a crude dinitrile stream is used to provide heat for the hydrogenation of a dinitrile to form a diamine.

Abstract: Disclosed is a method for hydrogenating a dinitrile to form a diamine. Also disclosed is a method for preparing a catalyst for this hydrogenation reaction by reducing iron oxide with hydrogen. The catalyst ages during the course of making the diamine. An aged catalyst is partially reactivated by abruptly interrupting the flow of feed to reactors.
