Pelletized activated carbon, method for producing pelletized activated carbon, and canister

摘要

A pelletized activated carbon and canister capable of reducing the amount of fuel gases evaporated and emitted into the atmosphere when a vehicle is stopped for a long time. A method for preparing the pelletized activated carbon including adding a binder and water to a powdery or granular activated carbon where the binder includes a cement (A) and at least one of a bentonite-based compound, a cellulose-based compound, and a polyvinyl alcohol-based compound; and the cement (A) is 30% by weight or more of the weight ratio of the solids; further including mixing with water to produce pellets of activated carbon. Pelletized activated carbon can be obtained by further hardening, drying, and cooling.
