Abstract: The present invention generally relates to a process for making a metal oxide composition for use in removing contaminants from streams. A process of the present disclosure comprises contacting a metal salt with an aqueous solvent to form a metal salt mixture and reacting the metal salt mixture and a metal powder without the addition of heat. The present invention also relates to a process for making a coated metal oxide substrate.

Abstract: In ridding fluids, including hydrocarbon fluids, both gaseous and liquid, of sulfur compounds including hydrogen sulfide, oxides of sulfur, and thiols, the present invention uses a small quantity of an activator, generally a noble metal oxide, preferably a copper species, along with a known oxide product, such as iron oxide or zinc oxide, to thoroughly remove sulfur contaminants in a short amount of time. The activator allows for the use of smaller reactor vessels and the production of hydrocarbon fluids substantially free of sulfur products.

Abstract: A product, capable of treating contaminated fluids, preferably gases, is disclosed. The product contains a carrier, an activated metal oxide, an odor counteractant, a carrier for the odor counteractant, and an agent which limits diffusion of the odor counteractant. The product removes sulfur contaminants, such as hydrogen sulfide and mercaptans, while also reducing and/or neutralizing other common odor causing compounds in fluids, preferably gases. Methods of making and using the product are also disclosed.

Abstract: In ridding fluids, including hydrocarbon fluids, both gaseous and liquid, of sulfur compounds including hydrogen sulfide, oxides of sulfur, and thiols, the present invention uses a small quantity of an activator, generally a noble metal oxide, preferably a copper species and/or a manganese species, along with a known oxide product, such as iron oxide, iron hydroxide, zinc oxide, zinc hydroxide, manganese oxide, manganese hydroxide, or combinations thereof, to thoroughly remove sulfur contaminants in a short amount of time. The activator allows for the use of smaller reactor vessels and the production of hydrocarbon fluids substantially free of sulfur products.

Abstract: The present invention relates to a compressed metal oxide composition particle comprised of metal oxide and an organic binder, with the binder preferably being a water insoluble cellulose composition. The present invention also relates to a method for forming a compressed metal oxide composition particle, with the preferred method including compressing a metal oxide and binder mixture to form compressed metal oxide composition particles having a final particle size of between about 0.1 mm and about 200 mm.

Abstract: A method is provided for removing carbonyl sulfide out of a H.sub.2 O-containing fluid stream, such as petrochemical vent gas, air, carbon dioxide, nitrogen and hydrocarbons, by determining how much carbon monoxide is present in the fluid stream; adding carbon monoxide to the fluid stream to obtain a carbon monoxide to carbonyl sulfide volume ratio of at least 1:1 and to also convert the carbonyl sulfide into hydrogen sulfide and carbon dioxide, and passing the hydrogen sulfide containing fluid through a hydrogen sulfide removal system, so as to obtain a fluid substantially free from carbonyl sulfide and hydrogen sulfide.
