Abstract
A hydrocarbon trap that includes a sheet paper element and a plurality of fingers. The paper element is at least partially formed of a material capable of adsorbing and desorbing gaseous hydrocarbons. The paper element is arranged into a plurality of adjacent sheet members. The fingers are disposed between and support adjacent pairs of the sheet members so that each adjacent pair of the sheet members forms a flow channel. A method for filtering gaseous hydrocarbons from an air flow is also provided.
