Disclosed in certain embodiments are methods of removing water from a gas feed stream comprising hydrocarbons and water during an adsorption step of an adsorption cycle.

Adsorbent bed with increased hydrothermal stability

An adsorbent composition comprises a bismuth material, a promoter and optionally a support. The adsorbent composition is suitable for adsorbing an arsenic material, such as arsine, from a process stream.

Arsine adsorbents

An absorbent composition having a bismuth material on a support containing at least one of a metal oxide, a metalloid oxide or an activated carbon and methods of making and using the same. The adsorbent composition is usful for adsorbing arsine from a fluid stream.

Adsorbents and methods of making and using adsorbents

An adsorbent composition having a bismuth material on a support containing at least one of a metal oxide, a metalloid oxide or an activated carbon and methods of making and using the same. The adsorbent composition is useful for adsorbing arsine from a fluid stream.

This invention is directed to amorphous and crystalline titanosilicate materials that have an unexpected selectivity for cesium and strontium, especially in the presence of high levels of competing ions. The titanosilicates of this invention show very high, unexpected selectivity in the presence of such competing cations such as sodium, calcium, magnesium and potassium, such as present in seawater.

Method of removing strontium cations from a water stream using an amorphous titanium silicate

Chemically combined chlorides are removed from intermediate and product streams of a hydrocarbon reforming process by contacting the streams with zeolite 13X, having a Si/Al ratio of less than 1.25.

Organic chloride adsorbent

An improved adsorbent useful in removing contaminants from various hydrocarbon streams comprises a zeolite, an alumina and an added metal component provided in the adsorbent by initially contacting primarily the zeolite with the added metal. In a specific application, an adsorbent comprising sodium-impregnated zeolite Y and alumina is used to purify an ethylene stream in order to remove CO, HS, methanol, and other S- and O-containing compounds.

Lower reactivity adsorbent and higher oxygenate capacity for removal of oxygenates from olefin streams

Recovering sulfur from a gas stream containing hydrogen sulfide by oxidizing the gas stream to convert the hydrogen sulfide in the gas stream to sulfur oxide, and thus form a sulfur oxide enriched gas stream. The sulfur oxide enriched gas stream is contacted with a solid, sulfation resistant adsorbent bed at relatively low temperatures to extract the sulfur oxides and retain them as sulfur compounds, thus forming a sulfur oxide depleted gas stream. The adsorbent bed is then contacted with an inert or reducing gas stream to reduce the retained sulfur compounds to sulfur and/or sulfur dioxide and thereby form an enriched sulfur and/or sulfur dioxide bearing stream. The elemental sulfur is recovered and/or the sulfur dioxide bearing stream may be recycled to the Claus unit for further conversion.

Process for the recovery of sulfur from Claus tail gas streams

Inorganic hydrated metal oxide and metal silicate gels are supported on the surface of particles of porous material by precipitation therein without significant deposit within pores of the support material and without encapsulating the particles of porous material. Especially preferred hydrated oxides and silicate gels are those of titanium. Preferred porous particles are composed of carbon. These novel composite materials are prepared by spraying an aqueous basic material onto the porous particles and then spraying a concentrated aqueous acidic solution of a source of suitable metallic ions so as to rapidly form a gelatinous precipitate on the surface of the porous particles which remain porous.

Composite ion-exchange material, preparation and use thereof

An in-line water purification system where all the water from a supply to a faucet opening enters a filter cartridge further includes a flow restrictor placed at the end of a faucet and which can be placed in a position so as to reduce water volume through said filtering system to remove the subjective control by the end user of water flow through the filtering device.
