Systems and methods for preventing biocorrosion of fuel handling components located in a sump in a fuel dispensing environment. One method includes exposing a hygroscopic material to moisture-laden air in the sump such that the hygroscopic material deliquesces into a liquid solution and exposing a buffer material to ethanol-blended fuel vapors in the sump. The method also includes collecting the liquid solution in a reservoir and monitoring the level of the liquid solution in the reservoir using a liquid level sensor. Further, the method includes notifying service personnel of the level of the liquid solution in the reservoir.

A carbon dioxide concentration control device (10) is provided with a control unit (15) that controls an absorption amount of carbon dioxide of a carbon dioxide absorbent (16) per unit hour, and a regeneration control unit (14) that generates the carbon dioxide absorbent (16), and a second drive energy supply unit (13) which is different from a first drive energy supply unit (11) that supplies power to the control unit (15) supplies power to the regeneration control unit (14), and thus a carbon dioxide concentration in a space is controlled to be an appropriate value for long periods of time.

Processes and systems for producing hydrogen gas utilizing a sorbent enhanced reformer in combination with a calciner operating at atmospheric pressure. Feed material is introduced into the sorbent enhanced reformer to produce carbon dioxide and hydrogen gas. Sorbent material within the reformer acts to absorb carbon dioxide and form a used sorbent. The used sorbent is introduced into the atmospheric calciner to heat the used sorbent to desorb carbon dioxide from the used sorbent to produce regenerated sorbent which can be recycled to the reformer.

A method for reducing the level of occluded alkali metal cations from an MSE-framework type molecular sieve comprises either (a) contacting the molecular sieve with a solution containing ammonium ions at a temperature of at least about 50 C. to ammonium-exchange at least part of the occluded potassium ions or (b) contacting the molecular sieve with steam at a temperature of at least about 300 C. and then subjecting the steamed molecular sieve to ammonium exchange.

A vapor separator in an embodiment is arranged between a first space and a second space, and is used to allow vapor existing in the first space to permeate in the second space by making a vapor pressure in the second space lower than a vapor pressure in the first space. The vapor separator in the embodiment includes: a porous body including a first face in contact with the first space and having a convexo-concave structure, a second face in contact with the second space, and fine pores passing to the second face from at least wall of the first face which constitutes the convexo-concave structure; and water existing in the fine pores of the porous body.

An apparatus for capture of CO.sub.2 from the atmosphere comprising an anion exchange material formed in a matrix exposed to a flow of the air.

Described are filter products and methods of using filter products, wherein the filter products include multiple cells, each cell containing an individual circulating fluidized beds during use.

A catalytic converter includes a hydrocarbon catalyst trap including BEA zeolite configured to adsorb iso-octane at ambient temperatures and desorb iso-octane at temperatures between 150 C. and 170 C., and active metal supercage impregnated USY zeolite configured to adsorb and coke iso-octane at temperatures greater than 150 C.

The invention describes a housing which aerates stone dust with ambient air or stone dust in an aqueous solution with concentrated CO2, the stone dust having a defined degree of humidity in order to absorb CO2. So that the stone dust does not escape from inside the housing, a plate system with a filter ensures that the stone dust is fixed in a certain position in the container.

So that the stone dust, which is moistened with the help of water mist in the supply air, does not clump and can be aerated more efficiently, the plates are partially in a state of vibration, which is generated by a frequency-controlled vibrating mechanism.

To empty the housing, the arrangement is pivoted through 180? and opened.

Preferred stones for the aeration material are granite, gneiss, gabbro and basalt rocks. Under certain circumstances, metallic parts are removed with a magnet so that the stone dust material can be used as fertilizer.

The present invention refers to a method for the production of granules comprising a magnesium ion-comprising material, granules comprising the magnesium ion-comprising material and the use of the granules in a nutraceutical product, agricultural product, veterinary product, cosmetic product, preferably in a dry cosmetic and/or dry skin care composition, home product, food product, packaging product, personal care product, preferably in an oral care composition in air treatment and in water treatment, or as excipient in a pharmaceutical product.
