Automotive Emission Control

In today’s highly regulated auto industry, evaporative emissions of volatile organic compounds (VOCs) from the vehicle must be controlled.

Automotive emissions are a major contributor to urban air pollution. Although exhaust emissions are effectively controlled using exhaust gas catalysts, activated carbon is the most common technology worldwide for evaporative fuel emissions. Activated carbon-filled canisters are used to adsorb high levels of volatile hydrocarbons in gasoline tank emissions to prevent them from moving into the ambient air. The adsorbed fuel vapors are then desorbed when the car is driven, regenerating the canister. This adsorption/desorption cycle continues allowing activated carbon to perform for the life of the vehicle. Our activated carbons adsorb higher levels of volatile hydrocarbons and desorb a maximum flow of hydrocarbon back into the air intake more efficiently than alternative activated carbons serving the market today.
