High capacity solid filtration media

摘要

A high capacity filtration media, method of preparing the media, and method of treating a fluid stream with the media are provided. The media contain a porous substrate impregnated with high concentrations of a permanganate. Preferably, the media includes a porous substrate impregnated with at least about 8% permanganate by weight. The media can optionally contain sodium bicarbonate. Improved capacity for the removal of undesirable compounds such as ethylene, formaldehyde, hydrogen sulfide and methyl mercaptan are achieved.

1. A method of treating a contaminated fluid stream comprising passing the contaminated fluid stream through a solid filtration composition such that at least one contaminant is removed from the fluid stream, wherein:
the contaminated fluid stream is passed through the solid filtration composition at a velocity of from 10 to 750 ft/min; the solid filtration composition comprises particles with a nominal ⅛″ particle size, the particles consisting of a dry porous substrate, a permanganate and water; the permanganate is a permanganate salt having a solubility in water greater than that of potassium permanganate; the concentration of permanganate salt in the solid filtration composition is approximately 15-20% permanganate salt by weight; and the porous substrate comprises activated alumina.
