Hexamethyldisiloxane Removal from Biogas Using a Fe₃O₄-Urea-Modified Three-Dimensional Graphene Aerogel.

ABSTRACT: Volatile methyl siloxanes (VMS), which are considered to be the most troublesome impurities in current biogas-cleaning technologies, need to be removed. In this study, we fabricated a series of Fe₃O₄-urea-modified reduced graphene-oxide aerogels (Fe₃O₄-urea-rGOAs) by using industrial-grade graphene oxide as the raw material. A fixed-bed dynamic adsorption setup was built, and the adsorption properties of the Fe₃O₄-urea-rGOAs for hexamethyldisiloxane (L2, as a VMS model pollutant) were studied. The properties of the as-prepared samples were investigated by employing various characterization techniques (SEM, TEM, FTIR, XRD, Raman spectroscopy, and N₂ adsorption/desorption techniques). The results showed that the Fe<
