Abstract: The present invention provides a catalyst for the oxidative dehydrogenation of a lower hydrocarbon to form at least one higher hydrocarbon and/or lower olefin. In one embodiment, the catalyst includes a nonstoichiometric rare earth oxycarbonate of the formula MxCyOz having a disordered and/or defect structure, wherein M is at elast one rare earth element selected from the group consisting of La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, and Tm; X = 2; Z = 3 + AY; A is less than about 1.8, and Y is the number of carbom atoms in the oxycarbonate. When used for the oxidative dehydrogenation of a lower hydrocarbon at a pressure above bout 100 psig. the catalyst has a selectivity of at least about 40 percent to at least one higher hydrocarbon and/or lower olefin. Methods for preparing catalysts taught by the invention and processes for using the catalysts for the oxidative dehydrogenation of lower hydrocarbons are also provided.

Abstract: La presente invencion proporciona metodos para la elaboracion de olefinas tales como etileno y propileno de alcanos inferiores, es decir, metano, etano y/o propano, mediante la deshidrogenacion oxidante a presion elevada. Las olefinas se recuperan selectivamente de alimentacion de alcano inferior sin convertir y los subproductos de reaccion al utilizar una separacion de formacion de complejos, tal como una separacion por absorcion que utiliza nitrato de plata acuoso como el agente de formacion de complejos. Los catalizadores que se utilizan dan selectividad elevada para deshidrogenacion oxidante de alcanos inferiores a olefinas a presion elevada, tal como catalizador de oxicarbonato de tierras raras no estequiometrico.

Abstract: The present invention provides methods for manufacturing olefins such as ethylene and propylene from lower alkanes, that is, methane, ethane and/or propane, by oxidative dehydrogenation at elevated pressure. The olefins are selectively recovered from unconverted lower alkane feed and reaction byproducts by using a complexation separation, such as an absorption separation that uses aqueous silver nitrate as the complexation agent. Catalysts are used that give high selectivity for oxidative dehydrogenation of lower alkanes to olefins at elevated pressure, such as a nonstoichiometric rare earth oxycarbonate catalyst.

Abstract: The present invention is directed to methods for the spray application of additive compositions containing additive materials in the manufacture of sheet material products, such as paper products, textile products, and flexible sheet products by using compressed fluids, such as carbon dioxide and ethane, as a spraying medium. Additive compositions with high viscosity and which are substantially free of water and/or volatile solvent can be applied to sheet materials. Water-borne additive compositions with reduced water content can also be applied to sheet materials. One preferred spray method uses a decompressive spray of the compressed fluid which produces a uniform spray pattern and a narrow droplet size distribution that can improve application efficiency and quality when additive compositions are applied during the spraying step to rapidly conveyed sheet materials.

Abstract: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, to form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions and can be sprayed at higher solids levels, in ambient air or with heated air applied to just the spray instead of a spray chamber. Novel catalyst supports can be produced having a beneficial morphology such as for olefin catalysis. Drier water-borne coatings can be applied to substrates by using compressed fluids to spray water-borne coating compositions having conventional water levels, thereby reducing runs and sags and shortening dry times.
