| Zusammenfassung: | A method for avoidance of attrited carbon dust is disclosed to lead to improved canister performance in emission control. Product attrition by dusting of granular and shaped activated carbons is disclosed to be reduced significantly, or essentially eliminated, by the application of a thin, continuous polymer coating on the granular or shaped activated carbon, without a reduction in adsorption velocity or capacity of the activated carbon when used in automotive emission control canisters. |
