High Temperature Sorption of Arsenic in Gasification Atmosphere M. Riess and M. Muller
Modern gasification technologies need to have low concentrations of impurities in the process gas for their failure-free operation.Therefore,hot gas cleaning is required.Molecular Beam Mass Spectrometry (MBMS) was used to determine the concentration of arsenic species in the hot gas downstream different sorbents at 800 ℃.Additionally,thermodynamic calculations regarding the release and the removal of arsenic using SimuSage were carried out.During the computer calculations copper containing sorbents were found to be suitable for the cleaning of arsenic-laden gases.This could be confirmed by MBMS retention experiments,where also high surface alumina appeared as an adequate sorbent material.Fly ash is also capable for arsenic retention,while zeolites,clay minerals and lime did not interact with arsenic
