GEO2 Technologies Introduces New Silicon Carbide Substrate for Diesel Particulate Filters
Patented, cross-linked microstructure breaks decades-old compromises in porosity and strength
Woburn, Mass., January 22, 2008 – GEO2 Technologies Inc., a leading developer of multifunctional filters for next-generation clean diesel solutions, today announced the introduction of a new silicon carbide (SiC) substrate for diesel particulate filtering. GEO2's patented microstructure is poised to drive the next wave of high-temperature filter innovation, effectively removing 99 percent of pollutants from diesel exhaust while achieving better fuel economy, emissions control and enhanced engine performance.
An industry first, GEO2's SiC substrate achieves high porosity and high strength simultaneously while delivering lower back pressure and high trapping efficiency. Also, unlike other SiC products, GEO2 filters are based on a cross-linked microstructure (CLM) that effectively reduces the size, weight and cost of emissions control systems.
"Today, the need for clean transportation technology is critical given a growing number of health and environmental issues associated with fossil fuels," said Bilal Zuberi, vice president and co-founder, GEO2 Technologies. "By innovating solutions such as the new cross-linked microstructure SiC diesel particulate filter, we can offer auto manufacturers an affordable means of controlling toxic particulate and CO2 emissions while preserving all the benefits of diesel fuel, including better gas mileage and improved vehicle performance."
Historically, diesel was seen as dirty and responsible for contributing wildly to global warming. However, innovations in the field have led to the emergence of clean diesel as one of the most viable solutions on the market for addressing today's emissions control challenges. Not only does clean diesel eliminate harmful pollutants from exhaust, but it also achieves 25 to 30 percent better fuel economy than gasoline.
"The industry needed a new material that could clean up emissions without the compromises associated with traditional filters, including higher cost and weight and reduced efficiency," continued Zuberi. "That's exactly what we've done with this new SiC filter – created a breakthrough material that can be integrated easily into existing vehicle platforms to improve performance."
In addition to SiC filters, the company offers a mullite filter, also based on its patented CLM that reduces the size, weight and cost of emissions control systems. GEO2's filters are the only high-temperature media to enable multiple functions within a single filter without sacrificing engine performance or profits. This technology can also be applied to non-automotive applications such as air-oil filtration, absorptive separation and pre-filtration.

About GEO2 Technologies
GEO2 Technologies Inc., a leading developer of multifunctional filters for next-generation clean diesel solutions, is helping to meet the global need for better fuel economy with reduced emissions. The company has pioneered a patented, cross-linked microstructure (CLM) for diesel particulate filtering and other gas and fluid emission control applications. This microstructure achieves the previously-unattainable combination of high porosity, high filtration efficiency, high temperature resistance and low back pressure. The filter, which breaks traditional compromises in strength and porosity, enables flexibility in system design and thereby reduces a system's cost, weight and size. As a result, automakers can offer clean diesel models more quickly and cost-effectively without downgrading performance. GEO2 works directly with ceramic and catalyst companies, as well as automakers, that design, manufacture and sell products based on GEO2's technology, to provide a competitive advantage in the fast-growth diesel market. Headquartered in Woburn, Mass., the company's proven materials technology was developed by respected scientists and engineers in the filtration, ceramics, emissions and automotive industries.
