Problems solved by technology

For example, due to the heat of adsorption generated, the adsorption vessel becomes hotter, which reduces the thermal conductivity of the granular adsorption material, resulting in a decrease in the capacity of the metal-organic framework (MOF) pellets.

preparation example Construction

[0047] In addition to the previously described conventional methods for preparing MOFs, eg in US 5,648,508, these can also be prepared electrochemically. In this respect, reference may be made to DE-A10355087 and WO-A2005 / 049892. Metal-organic frameworks prepared in this way have particularly good properties with regard to the adsorption and desorption of chemical substances, especially gases.

[0048] Particularly suitable materials for the sorbent in the sorption store are the metal-organic framework materials MOFA520, MOFZ377 and MOFC300.

[0049] MOFA520 is based on aluminum fumarate. The specific surface area (measured by porosity or nitrogen adsorption) of MOFA520 is usually in the range of 800m 2 / g to 2000m 2 / g range. The adsorption enthalpy of MOFA520 on natural gas reaches 17kJ / mol. More information on this type of MOF can be found in "Metal Organic Frameworks, Wiley-VCH Press, David Farrusseng, 2011". The pellets were all cylindrical with a length of 3 mm and...

Abstract

Filling device (22) for an ANG-sorption store (10) containing at least one adsorption medium (20) is provided, said filling device (22) being of tubular shape, having a mantle (36) defining a hollow interior, orifices (48) in said mantle (36), said ANG-sorption store (10) substantially mounted horizontally, wherein said orifices (48) are arranged on an upper part (62) of said mantle (36) of the filling device (22) extending in axial direction (34) through said ANG-sorption store (10).

Description

technical field [0001] The invention relates to a sorption store or sorber. Background technique [0002] Adsorbed natural gas (ANG) has the potential to replace compressed natural gas in mobile storage applications, such as automobiles. However, a large amount of research work has been dedicated to ANG, and few studies have evaluated the effect of the heat of adsorption on the system performance. Conversely, in ANG applications, micronized solids such as activated carbon are packed in a vessel to increase storage density, enabling lower-pressure operations with the same capacity. Adsorption is an exothermic process. Any adsorption or desorption is accompanied by temperature changes in the ANG storage system. The heat of adsorption can adversely affect performance during both fill and discharge cycles. A temperature rise of up to 80°C can occur during the fill cycle. Fill cycles are usually performed at fuel stations where the released heat of adsorption can be removed,...
