  • Patent number: 5162166
    Abstract: The present invention provides improved devices for the production of electrical energy from mixtures of oxygen (i.e., pure oxygen, air, or a similar source of free oxygen) and fuel (i.e., hydrogen and/or a hydrogen-yielding fuel). The devices generally comprise: a first electrode means for receiving electrons; a second electrode means for supplying electrons; and an electrolytic diffusion means, positioned between the two electrode means, for conducting ions from one electrode means to the other electrode means and for conducting oxygen and fuel, oxygen and hydrogen, or oxygen and a combination of fuel and hydrogen from one electrode means to the other electrode means (FIG. 1). At least one of the electrode means is permeable. Additionally, the first electrode means comprises a catalytic material which is a highly active catalyst for the formation of H.sub.2 O.sub.2 from H.sub.2 and O.sub.2.

  • Patent number: 4916243
    Abstract: This invention relates to a supported silver catalyst for the manufacture of ethylene oxide which contains a combination of (a) cesium and (b) at least one other alkali metal selected from the group consisting of lithium, sodium, potassium and rubidium, which combination comprises (a) and (b) in amounts in relation to the amount of silver therein sufficient to increase the efficiency of ethylene oxide manufacture to a value greater than the efficiencies obtainable under common conditions from respective catalysts which are the same as said catalyst except that instead of containing both (a) and (b), one contains the respective amount of (a), and the other contains the respective amount of (b). There is also described herein a process of making such catalyst and a process for producing ethylene oxide with such catalyst.
