    Abstract: A method of converting C 2 and/or higher alkanes to olefins by contacting a feedstock containing C 2 and/or higher alkanes with a first surface of a metal composite membrane of a sintered homogenous mixture of an AI oxide or stabilized or partially stabilized Zr oxide ceramic powder and a metal powder of one or more of Pd, Nb, V, Zr, Ta and/or alloys or mixtures thereof. The alkanes dehydrogenate to olefins by contact with the first surface with substantially only atomic hydrogen from the dehydrogenation of the alkanes passing through the metal composite membrane. Apparatus for effecting the conversion and separation is also disclosed.

    Abstract: The invention concerns a LaMO3 type composition, M being aluminium, gallium or indium, in powder or sintered form, its method of preparation and its use as conductor of oxygen. The compound in powder form is capable of reaching by loose powder sintering a density at least equal to 93 % of its theoretical density and of resulting in a sintered compound substantially free from an electrically active secondary phase at the grain boundary. The compound in powder form is obtained by reacting salts of lanthanum and of element M with a base then separating and calcining the resulting precipitate. It can also be obtained by mixing in a liquid medium salts of lanthanum and of element M and, optionally, of a base; then drying by pulverisation and calcination of the resulting precipitate. The sintered compound can be used in any application requiring a material in oxide form, oxygen conductive, such as fuel cells with solid oxides.

    Abstract: This invention is a chemical reactor and method for synthesis of hydrogen peroxide from molecular hydrogen and oxygen. The chemical reactor comprises a polymeric solution-diffusion membrane having a hydrogen contact side and an oxygen contact side and chambers for placing the relevant reactants in contact with the membrane. Conditions are provided such that a preferred flux of molecular hydrogen across the polymeric solution-diffusion membrane is at least five times greater than flux of the molecular oxygen across the membrane. The chemical reactor and method may be used to controllably synthesize hydrogen peroxide directly from molecular hydrogen and oxygen outside of the explosive range, without the use of organic solvents or complex equipment for ionic and electrical transport.
