Patent Title: Removal of branched dibenzothiophenes from hydrocarbon mixtures via charge transfer complexes with a TAPA-functionalized adsorbent
Publication date: 2012
Publication number: US8138369

Abstract: A process for producing an adsorbent where a metal oxide is reacted with an alkoxy silane to produce an epoxy-functionalized metal oxide. This product is reacted with an amino-substituted propionic acid and a nitro-substituted fluorenone, and this product is grafted to the epoxy-functionalized metal oxide. This grafted product is the adsorbent, which may be contacted with a hydrocarbon mixture having at least one sulfur containing compound in order to remove this sulfur containing compound. Also disclosed is a process for adding polymerization groups to an adsorbent.
