  • Characterization and ecological risk assessment of nanoparticulate CeO2 as a diesel fuel catalyst

    Nanoparticulate cerium dioxide (nano‐CeO2), when combusted as an additive to diesel fuel, was transformed from 6 nm to 14 nm sizes into particles near 43 nm, with no obvious change in the unit cell dimensions or crystalline form. Cerium sulfate, if formed during combustion, was below detection limits. Ceria nanoparticles were agglomerated within the soot matrix, with a mean aerodynamic ...

  • Effect of soot on N₂O formation over pt based diesel oxidation catalyst supported on microporous TiO₂

    Abstract The N2O formation over the diesel oxidation catalyst supported on microporous TiO2 has been investigated in the presence of the soot to simulate cold start or regeneration condition. The platinum (Pt) catalyst entrapped in micropore was resulted in the increase of the catalytic activity compared to the Pt catalyst supported on alumina. Also, it was shown that the ...

  • Composition and textural properties of soot and study of their oxidative elimination by catalytic process

    Diesel soot and reference carbon black samples have been characterised by analysis of the organic compounds fraction and determination of textural characteristics (specific area). The potential to eliminate such carbonaceous particles has been investigated using a Cu/ZrO2 solid catalyst promoted by potassium additives. The reactivity of soot samples depends on the organic compounds content. In ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • The emission characteristics of a compression ignition engine operating on castor oil methyl ester

    Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels.
