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.
