Ingevity supplies granular and shaped carbon and carbon honeycombs used in gasoline canister solutions that meet global regulations and customer demands globally. Our five decades of experience in gasoline vapor emissions control for the automobile industry mean you can trust our activated carbons to provide:

High gasoline working capacity
Nuchar® carbons have maximum porosity in the critical size range for fuel vapors, which provides the highest working capacity and low retention after purge. The resulting benefit is smaller, more efficient canister designs.

Low density
Nuchar® activated carbons are wood-based and have a volumetric weight 30 to 40% lower than other base materials, which saves money and reduces the canister’s weight.

Durability
To meet automotive industry and regulatory standards, activated carbon must retain its adsorptive and desorptive characteristics for the life of the vehicle. We’ve met these requirements for over 1 billion canisters worldwide to date.

Low diurnal emissions
Ever tightening regulations are driving the need to consistently reduce emissions from purged canister systems. Our activated carbon products are engineered to purge more efficiently, resulting in lower diffusional (bleed) emissions during diurnal cycling.

Low flow restriction
Our shaped and granular activated carbons come in a range of sizes so you can design canisters to achieve optimum flow characteristics. Low dust content and reliable particle size contribute to optimal flow restriction, which ensures consistent performance over the life of the vehicle.
