Abstract
A coated substrate () adapted for hydrocarbon adsorption having at least one surface, and a coating on the at least one surface, the coating comprising particulate carbon and a binder, wherein the particulate carbon has a BET surface area of at least about 1300 m/g; and at least one of: (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 ml/g and a mesopore volume greater than about 0.5 ml/g. A bleed emission scrubber () and an evaporative emission control canister system () comprising the coated substrate () are provided. They can control evaporative hydrocarbon emissions and may provide low diurnal breathing loss (DBL) emissions even under a low purge condition.
