摘要: A porous filter medium forms a filter or liner for extracting hydrocarbons from vapors emitted from a motorized vehicle, device or appliance fuel tank. The filter medium is a polymer network of a foam, nonwoven or collection of particles and has fine pore size and a butane working capacity (W/W %) of 4.0 percent or higher.
