Abstract
A system is provided within an electrophotographic imaging environment that removes or decomposes airborne hydrocarbons (as vapor and/or droplets), at least some of which are provided from evaporation or airborne dispersal of hydrocarbon carrier from electrophotographic toners or inks during and imaging process. The system has a catalyst that assists in the oxidation or decomposition of hydrocarbons and a (catalyst and vapor phase) heating and oxygen-providing components including a chemical oxygen-generator. The chemical reaction that occurs in the oxygen generation provides both a) immediate and significant amounts of heat that heats both the catalyst and the gas phase containing the hydrocarbon and the oxygen and b) oxygen to assist in the decomposition and/or oxidation of the hydrocarbon and other airborne materials.
