A molecular sieve adsorbent composition is provided that includes an inorganic molecular sieve having a surface and a native adsorption property. Carbon having a mean domain size of between 1 and 10 nm is deposited on the surface or admixed into contact with the surface in an amount to reduce the resistivity and within 10% of the native adsorption property. A method for producing an inorganic molecular sieve adsorbent composition includes the application of carbon having mean domain sizes of between 1 and 10 nanometers to a surface of the inorganic molecular sieve adsorbent composition at a temperature that does not exceed 400? C. and under a controlled gaseous environment to produce a carbon containing inorganic molecular sieve adsorbent composition. The carbon containing inorganic molecular sieve adsorbent composition is removed from the controlled gaseous environment to obtain the inorganic molecular sieve adsorbent composition with the decreased resistivity.

The present invention relates to new zeolitic adsorbent materials which are particularly specific and adapted for the non-cryogenic separation of gases, and more particularly for the separation of nitrogen by adsorption in gas streams such as air, and also for the purification of hydrogen by adsorption of carbon monoxide (CO) and/or nitrogen (N.sub.2), and also to the use thereof especially for the preparation of medical oxygen in oxygen concentrators for respiratory assistance.

The present invention relates to a zeolite-based adsorbent comprising at least one zeolite of FAU structure of LSX type and comprising barium and/or potassium, in which the outer surface area of said zeolite-based adsorbent, measured by nitrogen adsorption, is between 20 m.sup.2.Math.g.sup.1 and 100 m.sup.2.Math.g.sup.1, limits inclusive. The present invention also relates to the use of such a zeolite-based adsorbent as an adsorption agent, and also to the process for separating para-xylene from aromatic isomer fractions containing 8 carbon atoms.

Provided are a filtration material for filtered venting and a filtered venting device that are more effective in adsorbing radioactive iodine than in the conventional art and are useful for addressing severe accidents. The filtration material for filtered venting comprises granulated zeolite L, wherein at least a portion of the ion exchange sites of the zeolite L are substituted with silver. Of the ion exchange sites, a constitution ratio (a/b) of ion exchange sites (a) substituted with silver to ion exchange sites (b) not substituted with silver is 25/75-55/45. The zeolite L has a silver content of 7-12 wt % on a dry weight basis.

A catalyst for the dehydroaromatization of lower alkanes comprising boron in an amount of less than 1 wt % is supported on an inorganic support. The catalyst is useful in the production of aromatics from lower alkanes.

An integrated catalyst/adsorbent manufacturing process. The process includes generating electrical energy from a green energy source and providing the electrical energy to operate an electrolyzer, a steam generation unit, and a catalyst/adsorbent manufacturing unit. The electrolyzer operates to generate a hydrogen stream and an oxygen stream from electrolysis of a first stream of water and the steam generation unit operates by burning the hydrogen in the steam generation unit to generate heat to convert a second stream of water into steam. The catalyst/adsorbent manufacturing unit operates to produce the catalyst/adsorbent from the electrical energy, the steam, the hydrogen, the oxygen, and catalyst/adsorbent precursor chemicals provided to the catalyst/adsorbent manufacturing unit. Finally, the process includes capturing a carbon dioxide stream generated as a by-product of production of the catalyst/adsorbent in the catalyst/adsorbent manufacturing unit to generate the catalyst/adsorbent without CO.sub.2 emissions.

A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through the evacuation port.
