  • Patent number: 8715601
    Abstract: A method and apparatus are provided for reducing emissions of particulates from diesel engines. Exhaust is passed through a diesel particular filter having at least two stages comprised of (a) a catalyst section having a platinum group metal catalyst on contact surfaces within the catalyst section and (b) a filter section comprised of passages effective to remove particulates from a moving stream of combustion gases generated by combusting the fuel in the engine and holding them therein to permit their oxidation. Carbon removal is enhanced by utilizing levels of platinum group metal composition, cerium compositions, fuels and/or optional chemical enhancers to generate NO2 in the catalyst section in amounts sufficient to form cerium nitrates in the filter section. The cerium oxide is associated with and maintains dispersion of the platinum in the filter section, and the cerium nitrates are available at the surface and within the soot particles to provide enhanced soot oxidation at a lower balance point.

  • Publication number: 20130245252
    Abstract: A process is disclosed for conversion of cellulose in an Ionic Liquid medium. The process is characterized in that a cellulose-containing feedstock and an Ionic Liquid are mixed at a temperature below 80 ° C. The mixture is heated to a conversion temperature in the range of 80 ° C. to 220 ° C. under a hydrogen atmosphere. The presence of hydrogen during the heating step significantly reduces the formation of degradation products.
