Abstract
A porous material, including metal organic frameworks (MOFs) and porous organic polymer (POP), with reactivity with or sorptive affinity towards (a) electronic gas to substantially remove or abate electronic gas in an electronic gas-containing effluent, or (b) contaminants in a stream of electronic gas to substantially remove the contaminants from a stream of electronic gas and increase the purity of said electronic gas, or (c) trace mercury contaminant in a hydrocarbon stream to substantially remove said mercury contaminant and increase the purity of said hydrocarbon stream. MOFs are the coordination product of metal ions and multidentate organic ligands, whereas POPs are the product of polymerization between organic monomers.
