Carbon canister recovery

Evaporative emissions from the fuel tank and carburetor have been controlled on all 1971 and later model automobiles sold in the United States. This has been accomplished by either a vapor recovery system which uses the crankcase of the engine for the storage of the hydrocarbon vapors or an adsorption and regeneration system using a canister of activated carbon to trap the vapors and hold them until such time as a fresh air purge through the canister carries the vapors to the induction system for burning in the combustion chamber. 

The USA demand for activated carbon will very probably reach 200,000 tonnes per year by 2005, and the market will very probably be negatively affected by imports from the Asia-Pacific region. The trend is for more rapid growth in gas-phase applications, mainly air purification, solvent recovery and motor vehicle emission canisters. This means that granular activated carbon will have a better growth potential than powdered activated carbon.
