  • Regeneration Method For Ceramic Honeycomb Structures
    Publication number: 20110252770
    Abstract: A method for regenerating a diesel particulate filter includes elevating a temperature of a gas stream flowing into an inlet of the diesel particulate filter to greater than or equal to 450° of the inlet of the diesel particulate filter, wherein the gas stream at the inlet of the diesel particulate filter contains an amount of NOx of equal to or greater than 300 ppm, and an amount of O2 of equal to or greater than 5% volume, thereby burning the soot within the diesel particulate filter. The method also includes elevating a temperature of the gas stream flowing into the inlet of the diesel particulate filter to less than or equal to 550° C. at the inlet of the diesel particulate filter, wherein a burn rate of soot from porous walls of the diesel particulate filter is greater than or equal to 3.8 grams/liter/hour.
    Type: Application

  • Regeneration method for ceramic honeycomb structures
    Publication number: 20090019831
    Abstract: A method for regenerating a diesel particulate filter includes elevating a temperature of a gas stream flowing into an inlet of the diesel particulate fitter to greater than or equal to 450° of the inlet of the diesel particulate filter, wherein the gas stream at the inlet of the diesel particulate fitter contains an amount of NOx of equal to or greater than 300 ppm, and an amount of O2 of equal to or greater than 5% volume, thereby burning the soot within the diesel particulate fitter. The method also includes elevating a temperature of the gas stream flowing into the inlet of the diesel particulate filter to less than or equal to 550° C. at the inlet of the diesel particulate fitter, wherein a burn rate of soot from porous watts of the diesel particulate filter is greater than or equal to 3.8 grams/liter/hour.
