Abstract: The present invention is directed toward a highly active aromatics hydrogenation catalyst and its use. The catalyst composition is prepared by:(a) decomposing a catalyst precursor selected from the group consisting of metal amine molybdates, metal amine tungstates and mixtures thereof, wherein said metal amine catalyst precursor has the general formulaML(Mo.sub.y W.sub.1-y O.sub.4)awhere M is Cr and/or one or more divalent promoter metals selected from the group consisting of Mn, Fe, Co, Ni, Cu and Zn; L is one or more neutral nitrogen containing ligands at least one of which is a chelating polydentate ligand; 0.ltoreq.y.ltoreq.1; and a=1 for non-chromium containing catalysts and wherein 0.5.ltoreq.a.ltoreq.3 for chromium containing catalysts, at a temperature of about 200.degree. to about 400.degree. C. in an inert atmosphere; and(b) reducing at a temperature of about 300.degree. to about 450.degree. C. said metal amine catalyst precursor to form a catalyst.

Abstract: The present invention is directed to an electric current-producing cell which contains:(a) an anode having as its anode-active material one or more metals selected from a group consisting of Periodic Table Group Ia metals, Group Ib metals, Group IIa metals and Group IIb metals;a cathode, comprising:(i) metalized containment means having a plurality of apertures therein, said apertures having an average cross-sectional dimension of about 1 to about 100 microns; and(ii) cathode-active molybdenum sulfide contained within said metalized containment means; and(c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between said anode and said cathode.
