An oral chewable tobacco product includes a gum composition in an amount of about 30% to about 70% by weight based on the weight of the oral chewable tobacco product and tobacco powder in an amount of about 30% to about 70% by weight based on the weight of the oral chewable tobacco product. The gum composition includes at least one environmentally biodegradable polymer in an amount of about 20% to about 95% by weight based on the weight of the gum composition and at least one softener in an amount of about 5% to about 80% by weight based on the weight of the gum composition.

Oral chewable tobacco product and method of manufacture thereof

According to one embodiment, described herein is an exhaust gas after-treatment system that is coupleable in exhaust gas stream receiving communication with an internal combustion engine. The exhaust gas after-treatment system includes a low temperature SCR catalyst configured to reduce NOin exhaust gas having a temperature below a temperature threshold. The system also includes a normal-to-high temperature SCR catalyst configured to reduce NOin exhaust gas having a temperature above the temperature threshold.

Low temperature selective catalytic reduction catalyst and associated systems and methods

Catalysts for the conversion, or oxidation, of carbon monoxide to carbon dioxide. Cigarettes with filters containing the catalysts have acceptable resistance to draw. Additionally, the catalysts can be used to reduce the concentration of carbon monoxide from a vehicle exhaust emission, a gas used in a COlaser, a gas used in a fuel cell and/or ambient air undergoing air filtration.
