Abstract

This invention relates in certain aspects to a process for removing oxygenates from a stream, preferably a hydrocarbon stream comprising contacting an organosilica material with the hydrocarbon steam, where the organosilica material is a polymer of at least one monomer of Formula [Z1OZ2SiCH2]3, wherein Z1 represents a hydrogen atom, a C1-C4 alkyl group, or a bond to a silicon atom of another monomer and Z2 represents a hydroxyl group, a C1-C4 alkoxy group, a C1-C6 alkyl group or an oxygen atom bonded to a silicon atom of another monomer.
