Adsorbent monolith containing activated carbon, method for producing this monolith, and method for adsorbing chemicals from fluid streams

摘要

An adsorptive monolith made by extruding a mixture of activated carbon, a ceramic forming material, a flux material, and water, drying the extruded monolith, and firing the dried monolith at a temperature and for a time peri od sufficient to react the ceramic material together and form a ceramic matrix. The extrudable mixture may also comprise a wet binder. The monolith has a shape with at least one passage therethrough and desirably has a plurality o f passages therethrough to form a honeycomb. The monolith may be dried by vacu um drying, freeze drying, or control humidity drying. The monolith is useful fo r removing volatile organic compounds and other chemical agents such as ozone from fluid streams. Particularly useful applications include adsorptive filters for removing ozone from xerographic devices and other appropriate office machines and volatile organic compounds from automobile engine air intake systems.
