Abstract: THE PRESENT INVENTION PROVIDES METHOD FOR MANUFACTURING OLEFINS SUCH AS ETHYLENE AND PROPYLENE FROM LOWER ALKANES (5), THAT IS, METHANE, ETHANE AND/OR PROPANE, BY OXIDATIVE DEHYDROGENATION AT ELEVATED PRESSURE. THE OLEFINS ARE SELECTIVELY RECOVERED FROM UNCONVERTED LOWER ALKANE (10) 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 (5) TO OLEFINS (8) 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 composition s with high viscosity and which are substantially free of water and/or volatile solvent can be applied to sheet materials. Water-home 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: 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 spraying polymeric compositions with supercritical or subcritical compressed fluids such as carbon dioxide or ethane over a wider range of spray conditions to provide improved spray application quality with reduced emission of solvent. The methods are accomplished by using an elongated spray orifice to transform narrow, fishtail, liquid-film sprays to wider, feathered, decompressive sprays.
