Sponge to absorb pollution, the successful development of crystal
Japanese scientists have developed a crystal sponge, you can start working before the catalytic converter to reduce absorption of pollutant emissions from vehicles.

Tokyo University, a research team found that zeolite can be used - a silicon, aluminum and oxygen to form crystals - to absorb hydrocarbons.

Vehicle emissions of hydrocarbons, 80% in the catalytic converter reaches its operating temperature prior to discharge into the atmosphere.

New cars are usually equipped with a catalytic converter, it can not burn the gas in most of the burned hydrocarbons into carbon dioxide.

But the problem is how to prevent the converter gets hot before the hydrocarbon pollution of the environment tiffany bracelet.

Known as SSZ-3 zeolite zeolite can absorb more than 2 more than 30% of the hydrocarbons, but also in the high temperature (about 800 degrees Celsius), the easily damaged.

Atoms into the zeolite in the ring to form three-dimensional framework, you can start the engine after a few minutes to absorb pollutants.

2 previously used porous zeolite, in hot, humid conditions will fall off, making it impossible to absorb hydrocarbons.
