A method for making the thin film composite gas separation membrane is provided as well as the use of the membrane for a variety of separations such as separations of hydrogen sulfide and carbon dioxide from natural gas, carbon dioxide removal from flue gas, fuel gas conditioning, hydrogen/methane, polar molecules, and ammonia mixtures with methane, nitrogen or hydrogen and other light gases separations, but also for natural gas liquids recovery and hydrogen sulfide and carbon dioxide removal from natural gas in a single step.

The present disclosure provides a gas separation membrane module that has high, long-term utility. The present disclosure provides a gas separation membrane module that has: a housing; a gas separation membrane that is arranged inside the housing; and an adhesive part that fixes the gas separation membrane to the housing.

A method of forming a hydrocarbon product and a protonation product comprises introducing C.sub.2H.sub.6 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10.sup.−2 S/cm at one or more temperatures within a range of from about 150° C. to about 650° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the protonation product. A C.sub.2H.sub.6 activation system and an electrochemical cell are also described.

Mixed adsorbent/desiccant beds comprising in some embodiments from about 20 vol % (volume percent) to about 90 vol % of one or more adsorbents and from about 10 vol % to about 80 vol % of one or more desiccants, based on the total volume of the adsorbent/desiccant mixture, prevent water reflux during thermal regeneration of adsorption beds in gas processing plants and methods.

Process for preparing a catalyst or a trapping mass comprising the following steps: bringing a porous oxide support into contact with a metal salt comprising at least one metal belonging to groups VIB, VIIB, VIIIB, IB or IIB, of which the melting point of said metal salt is between 20° C. and 150° C., for a period of between 5 minutes and 5 hours in order to form a solid mixture, the weight ratio of said metal salt to said porous oxide support being between 0.1 and 1; heating the solid mixture with stirring at a temperature between the melting point of said metal salt and 200° C. and for 5 minutes to 12 hours; calcining the solid obtained in the preceding step at a temperature above 200° C. and below or equal to 1100° C. under an inert atmosphere or under an oxygen-containing atmosphere.

A membrane is described for purifying or separating hydrogen from a multi-component gas stream such as syngas. This membrane uses a molecular pre-treatment, a transition metal, fluorine containing polymer, carbon fibers and carbon matrix sintered on a supportive screen. The membrane may be a bilayer membrane comprised of a layer containing high surface area carbon and another layer containing lower surface area carbon. Methods for purifying hydrogen are also described.

A reclaimer system and methods for using said reclaimer system to reclaim one or more amine agents from a fluid containing one or more degradation products that have been formed from the reaction of one or more acid gas components with the one or more amine agents.

The present invention addresses to the use of NaY zeolite with a Si/Al ratio >2.6 as a solid adsorbent in the process of removing H.sub.2S from natural gas through a PSA process. The described adsorbent has the capacity of removing H.sub.2S from natural gas from offshore exploration platforms, enabling in situ regeneration. The experimental development proved the high capacity of capturing H.sub.2S by the NaY zeolite in consecutive cycles of pressurization, adsorption, depressurization and purging. This capture capacity remains at 74.2% of the initial capacity, remaining stable in subsequent cycles. The structure of the material maintained crystallinity above 95% in use, in 15 consecutive cycles, allowing the reuse of the adsorbent for a prolonged period of operation, preventing the solid from being constantly changed, which is quite common in a non-regenerative process.

Provided herein are one-step methods for fabricating an asymmetric mixed-matrix membrane and the asymmetric mixed matrix membrane so fabricated. In the one step method an asymmetric polymer film is formed from a liquid polymer solution and a ligand precursor simultaneously with the formation of metal-organic framework filler particles therein. Also provided is a method for separating a mixture of gases or of liquids by flowing the mixture through the asymmetric mixed matrix membrane.
