ABSTRACT:
A composition containing silica and vanadium, wherein at least a portion of the vanadium is present as a distorted octahedral and in a phase selected from the group consisting of amorphous, nano-crystalline, and combinations thereof, is disclosed. A method of preparing such composition is also disclosed. The composition is employed in a process to remove a heavy metal from a gaseous feed stream which can optionally include a separate heavy metal adsorption stage.
