WEVTU learns that commercialization of a technology that regenerates diesel particulate filters without use of platinum group metals (PGM) catalysts is moving forward. A patent issued to Lawrence Livermore National Laboratory reportedly explains that when a sufficient electrical charge (non-thermal plasma) is applied to diesel exhaust, nitrogen oxide (NO) is converted to nitrogen dioxide (NO2), which reduces the temperature at which carbon particulate trapped in filters is oxidized. As ...
