Abstract: THERE ARE PROVIDED NOVEL COMPLEX COMPOUNDS OF THE GENERAL FORMULA

(L)N-ME-ME-(L)N

WHEREIN ME IS IR, AND L IS A COMPLEXING COMPOUND SELECTED FROM PHOSPHINES. THE NEW COMPLEXES ARE PREPARED BY TRANSFORMING A COMPOUND OF IRIDIUM INTO AT LEAST A PARTIAL HYDRIDE, THEN DEHYDROGENATING THIS IN THE PRESENCE OF A HYDROGEN ACCEPTOR AND OF A COMPLEXING AGENT. THE NEW COMPLEX COMPOUNDS HAVE CATALYTIC ACTIVITY, E.G., IN THE TRANSFER OF HYDROGEN IN UNSATURATED COMPOUNDS.

Abstract: A multi-stage countercurrent process for the solvent extraction of aromatic hydrocarbons from a mixed feed stock is disclosed wherein the feed is contacted with a keto- or aldo-morpholine and extracted in a first stage, extract from the first stage is purified in a second stage by countercurrent contact with an overhead fraction from a third stage wherein the second stage extract is distilled, and rectification is effected in a fourth stage wherein water is refluxed and a part of the water, obtained as reflux free of solvent, is vaporized and recycled to the bottom of this rectification stage to recover the sensible heat of lean solvent.

Abstract: METHODS ARE DISCLOSED FOR ELIMINATING CARBON FROM NUCLEAR FUEL ELEMENTS IN THE REPROCESSING THEREOF IN A CLOSED SYSTEM. IN ONE EMBODIMENT, THE CARBON IS REACTED WITH CARBON DIOXIDE TO FORM CARBON MONOXIDE IN AN ATTACK ZONE WHICH IS MAINTAINED AT A TEMPERATURE OF ABOUT 1000*C., THE CARBON MONOXIDE IS THEN CAUSED TO FLOW TO A REGENERATION ZONE WHICH IS MAINTAINED AT A LOWER TEMPERATURE SO THAT A REVERSE REACTION OCCURS WHICH CONVERTS THE CARBON MONOXIDE INTO CARBON DIOXIDE AND REGENERATED CARBON, THE CARBON DIOXIDE FLOWS BACK TO THE ATTACK ZONE LEAVING THE REGENERATED CARBON BEHIND IN THE REGENERATION ZONE.
