Trace hydrogen may be removed from a dry gas by passing the dry gas at a temperature from about 0&#xb0; C. to about 60&#xb0; C. through at least one layer of a first hopcalite catalyst to produce product gas that is at least substantially free of hydrogen, wherein the first hopcalite catalyst has a molar ratio of copper to manganese of more than 0.55. Advantages include increase hydrogen capacity, lower feed and regeneration temperatures and lower sensitivity to carbon dioxide than equivalent processes using standard hopcalite catalyst having a Cu/Mn molar ratio from 0.45 to 0.55.

Removal of hydrogen impurity from gas streams

Disclosed herein are rapid cycle pressure swing adsorption (PSA) process for separating Ofrom Nand/or Ar. The processes use a carbon molecular sieve (CMS) adsorbent having an O/Nand/or O/Ar kinetic selectivity of at least 5 and an Oadsorption rate (1/s) of at least 0.2000 as determined by linear driving force model at 1 atma and 86&#xb0; F.

Carbon molecular sieve adsorbent

An adsorbent for removing COfrom a gas mixture, the adsorbent comprising alumina and a carbonate compound where the carbonate to alumina IR absorbance intensity ratio is reduced by washing the adsorbent with water. The disclosure also describes a method of making adsorbent particles, process for removing COfrom a gas mixture using the adsorbent, and an adsorption unit using the adsorbent.

Alkali-promoted activated alumina adsorbent

A rapid cycle pressure swing adsorption (RCPSA) air purification process, apparatus, and device for the removal of at least one of water, carbon dioxide, nitrous oxide, and one or more hydrocarbons from a feed air stream prior to cryogenic air separation.

Rapid cycle pressure swing adsorption process and adsorbent laminates for use therein

Disclosed herein are multi-bed rapid cycle pressure swing adsorption (RCPSA) processes for separating Ofrom Nand/or Ar, wherein the process utilizes at least five adsorption beds each comprising a kinetically selective adsorbent for Ohaving an Oadsorption rate (1/s) of at least 0.20 as determined by linear driving force model at 1 atma and 86&#xb0; F.

Multi-bed rapid cycle kinetic PSA

Disclosed herein are novel RHO zeolites useful as kinetically selective adsorbents for oxygen and/or nitrogen. The adsorbents can be used in pressure swing adsorption processes for selectively adsorbing oxygen and/or nitrogen from feed streams such as an air stream or crude argon stream. Also disclosed are novel methods of preparing RHO zeolites, including in particular mixed-cation RHO zeolites.

RHO adsorbent compositions, methods of making and using them

Disclosed herein are new processes for adsorbing oxygen using adsorbent compositions comprising RHO zeolites kinetically selective for oxygen. The RHO zeolites can be used in pressure swing adsorption processes for separating oxygen from oxygen containing streams, such as for, but not limited to, purifying a crude argon feed stream or separating oxygen from an air feed stream.

Processes using improved RHO adsorbent compositions

The invention provides systems and methods for separating ethane and heavier hydrocarbons from a natural gas stream. In aspects of the invention, an adsorption unit is integrated with a cryogenic gas processing plant in order to overcome methane recovery limitations by sending the tail gas from the adsorption unit to the cryogenic gas processing plant to recover methane that would otherwise be lost.

Natural gas processing plant

Embodiments of the present invention provide systems and methods for efficiently producing both a low-pressure ozone stream and high-pressure oxygen stream using a single air separation unit. The low-pressure ozone stream and high-pressure oxygen stream can be produced with significant energy savings and can be used in variety of applications, including the extraction of precious metals from ore with aqueous oxidation reactors and high-pressure oxidation reactors.

Integrated process for production of ozone and oxygen

Process of reducing water, COand NO in feed air, which: a first adsorbent such as alumina (25-40% volume) and a second adsorbent such as X zeolite (60-75% volume) are used; the online time of the adsorbent is determined by determining the concentration measured by an analyzer for COconcentration at a position within the length of the second adsorbent when a maximum level of NO is simultaneously obtained at the downstream end of the second adsorbent in the feed direction, wherein the online time is the time taken from commencing passing the feed air to the first and second adsorbents to the measurement by the analyzer of the determined concentration of CO; at least the second adsorbent is regenerated by heated regeneration gas at a temperature of 140&#xb0; C.-220&#xb0; C.; and the molar ratio of the regenerating gas to feed air supplied during one iteration of the cycle is 0.08-0.5.

Purification of air

Hydrogen and carbon monoxide impurities are removed from a dry gas comprising the impurities, wherein the dry gas is at least substantially free of carbon dioxide, by passing the dry gas with sufficient residence time, e.g. at least 1.5 s, through a layer of catalyst comprising a mixture of manganese oxide and copper oxide. The use of expensive noble metal catalysts to remove hydrogen may thereby be avoided. In addition, regeneration of the catalyst using oxygen-containing regeneration gas does not reduce the effectiveness of the catalyst.

Removal of hydrogen and carbon monoxide impurities from gas streams

Composite adsorbent beads have a porous and non-adsorbent core comprising at least one inorganic material and a porous and adsorbent shell comprising at least one adsorbent layer comprising a porous adsorbent material on the surface of the core. The core preferably comprises agglomerated inorganic particles having a mean particle size equal to or smaller than the mean particle size of the surrounding agglomerated adsorbent particles. The beads preferably are manufactured by calcining together a non-sintered core and the adsorbent layer. The beads can be used at the outlet end of an adsorption column to improve performance.

Method for recovering a desired component from a waste gas comprising (a) at an operating facility, introducing a waste gas comprising the desired component and one or more undesired components into an adsorber containing adsorbent material selective for the desired component, adsorbing at least a portion of the desired component therein, (b) terminating flow of waste gas into the adsorber; and (c) recovering and concentrating the desired component by either (1) isolating the adsorber, transporting the adsorber to a central processing facility, or (2) withdrawing from the adsorber an intermediate gas enriched in the desired component, compressing the intermediate gas and storing it in a vessel, isolating the vessel, transporting the vessel to a central processing facility to provide a concentrated product further enriched in the desired component.

Method for recovering high-value components from waste gas streams

Both power and Hare produced from a gaseous mixture, comprising Hand CO, using first and second pressure swing adsorption (PSA) systems in series. The gaseous mixture is fed at super-atmospheric pressure to the first PSA system, which comprises adsorbent that selectively adsorbs COat said pressure, and COis adsorbed, thereby providing an H-enriched mixture at super-atmospheric pressure. A fuel stream is formed from a portion of the H-enriched mixture, which is combusted and the combustion effluent expanded to generate power. Another portion of the H-enriched mixture is sent to the second PSA system, which comprises adsorbent that selectively adsorbs COat super-atmospheric pressure, and COis adsorbed, thereby providing a high purity Hproduct. In preferred embodiments, the division of H-enriched mixture between forming the fuel stream and being fed to the second PSA system is adjustable.
