Urban, W.W.UrbanUnger, C.C.Unger2022-03-082022-03-082006https://publica.fraunhofer.de/handle/publica/307275Die Erfindung betrifft eine Sorptionseinheit zur Entfernung organischer Siliziumverbindungen aus biogenen und/oder anthropogenen Gasen. Das Sorbens besteht dabei aus einem hydrophobierten Kieselgel. Gleichzeitig betrifft die Erfindung die Verwendung von hydrophobiertem Kieselgel als selektives Sorbens fuer siliziumorganische Verbindungen in anthropogenen oder biogenen, methanhaltigen Gasen. Hierzu zaehlen u. a. Biogas, Klaergas oder Deponiegas.DE1004051807 A UPAB: 20060620 NOVELTY - Hydrophobized silica gel is used as a selective sorbent for organosilicon compounds in biogenic and/or anthropogenic gases. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a sorption unit for removing organosilicon compounds from biogenic and/or anthropogenic gases, in which the sorbent is hydrophobized silica gel with an average pore radius of 1-40 nm. USE - Used for removing organosilicon compounds from biogenic and/or anthropogenic gases, especially methane-containing gases, e.g. biogas, sewage gas or landfill gas, preferably in a fixed-, mobile- or fluidized-bed adsorption unit. ADVANTAGE - Hydrophobized silica gel is less expensive than active carbon and can be regenerated and re-used.de608620patent102004051807
