Abstract:
1. A filtration system comprising: a) a plurality of layers, each layer being reactive and including a matrix of sinter-bonded microfibers; b) support, adsorbent or reactive particulates and/or fibers entrapped within said matrix; c) a pre-selected reactive material impregnated into said matrix and supported by said particulates and/or fibers; d) wherein thin sheets of the matrix with the supporting particulates, reactants, adsorbents and/or fibers and the pre-selected reactive materials impregnated therein are chemically functionalized and then stacked in a pre-defined sequence; and e) wherein the predefined sequence has an upstream packed bed of larger diameter reactive catalyst and sorbent particulates and a downstream polishing layer of smaller diameter microfibrous entrapped reactive catalyst and sorbent particulates; and f) wherein the filtration system removes contaminants from liquid and gaseous streams.
