In particular the vessel and desiccant material contained therein are sized to produce a dew point suppression of less than 50° C.

The invention relates to a filter element (10), including a filter body (12) with a self-contained exterior side (50) which surrounds a self-contained interior side (52), at least one filter medium (16) being disposed between exterior side (50) and interior side (52) and the filter body (12) including at least in some areas at least one winding layer (14) with at least one adsorbent. The invention relates furthermore to a filter system (100) with a filter element (10) with a filter body (12) with a self-contained exterior side (50) which surrounds a self-contained interior side (52), at least one filter medium (16) being disposed between exterior side (50) and interior side (52), the filter body (12) including at least in some areas at least one winding layer (14) with at least one adsorbent.

There is provided an absorbent for decreasing the leakage of halogen compound gases in subsequent processes, at high temperatures and in the presence of high concentrations of water vapor in the process of heating and gasifying a fuel, such as coal, to produce a synthesis gas.

The adsorbent includes a halogen compound absorbent containing 30 to 90% by mass of a basic calcium compound and 10 to 70% by mass of a metal compound other than basic calcium compounds and/or of a clay mineral. A method for producing synthesis gas using the absorbent is also disclosed.

Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

A device for treating a gas laden with pollutants, includes at least one adsorption module for adsorbing the pollutants, which is utilized in an adsorption apparatus. The adsorption module includes at least one electrically conductive layer of an activated carbon fiber mat, an electric current circuit for heating the activated carbon fiber mat for the desorption of the adsorbed pollutants, and distributing conduit which is routed into the center of the adsorption module and has outlet openings for a flush gas for inertizing and rinsing the activated carbon fiber mat.

Filter media and filters for the sequestration of carbon dioxide are disclosed. The carbon dioxide sequestering filter media incorporate silicate minerals, and the carbon dioxide sequestering filters incorporate carbon dioxide sequestering filter media. Filters using only carbon dioxide sequestering media and filters combining carbon dioxide sequestering media with traditional air filter media are disclosed. The carbon dioxide sequestering filters may be used instead of traditional air filters in residential, commercial and industrial applications.

A radial U-flow adsorption unit for air purification in a TSA process, having a gas outlet at one end and at least one gas inlet at the side, preferably at the same end of the unit as the gas outlet. The simpler design of the unit facilitates manufacture, installation and transport, and reduces the capital and operating costs.

An air purification device includes a device main body, a purification filter and a gas detection module. The device main body includes a gas-inlet opening and a gas-outlet opening. The purification filter is disposed in the device main body and includes at least one activated carbon layer and at least one zeolite layer stacked on each other, wherein the activated carbon layer filters and absorbs suspended particles contained in an air introduced through the gas-inlet opening, and the zeolite layer includes porous structures with hydrophobic property for controlling and absorbing volatile organic compounds contained in the air introduced through the gas-inlet opening, thereby a purified gas is generated from the air and is discharged through the gas-outlet opening. The gas detection module is disposed in the device main body for detecting and obtaining a gas quality data of the air passing through the gas-inlet opening and outputting the gas quality data.
