The U.S. Environmental Protection Agency (EPA) typically aims the start date of a new standard toward a point in the future when it projects that the technologies designed to meet the standard will become commercialized. So it was in December 2000, when the agency ruled that a 95% cut in allowed nitrogen oxide(NO
An affordable, logistically sensible exhaust aftertreatment technology to meet that standard did not exist when the ruling was enacted in 2000. Although several technologies have been developed to address the NOx problem each solution has a logistics penalty for the consumer. Additionally, they have not been able to meet the 95% NOx reduction threshold mandated by US EPA....Until now. . . .
Clear Skies Unlimited will soon introduce the MaxCAT Emission Control Device which incorporates a revolutionary catalytic technology. Our preliminary test results are very exciting.
Our new catalyst technology will perform extremely well with a number of diesel and diesel-type fuels, including standard diesel, synthetic diesel, bio-diesel and JP8, which is a jet fuel preferred by the military.
Our future research plans for this technology call for expanded work aimed at both natural gas engines and coal-fired power plants.
Clear Skies Reticulated Structure
Our new catalytic technology will employ the same ceramic structure that we use for our other catalytic products. Our reticulated structure is much more efficient than any competing catalytic substrate design.
NOx and other pollutants in the diesel exhaust are removed by positioning reticulated foam treated with our proprietary catalytic coating between the engine and the exhaust termination. The reticulated foam is a three dimensional latticework of interconnected ligaments forming a porous, open-celled structure with a large internal surface area. The internal surfaces are coated with the catalytic material which converts the pollutants in the exhaust to harmless compounds. We also offer "metal" reticulated foam for those very demanding applications.
The MaxCAT ECD Design
The MaxCAT unit is a two stage device about the size of an under-carriage muffler system. Heat from the exhaust, when the diesel is operating, maintains the catalyst at a adequate temperature for efficient conversion operation. The first stage of the Emission Control Device ECD is a standard CS-200 Clear Skies catalyst for PM and CO reduction. The second stage element is treated with our "new" catalyst for NOx performance and final catalytic filtration. This two stage unit provides Total Emission Control. The Clear Skies Research and Development Group is moving forward with prototyping and proof-of-concept development for the Technology Verification Testing for US EPA and California Air Resources Board CARB.
