By use of coal fly ash as an additive in pulverized biomass fuel boilers, harmful alkali species can be bound alumina silicates that are less harmful. In this study, potassium scavenging ...
We have deposited a series of WC–Co coatings by the high velocity oxy fuel (HVOF) process, using three different powders, and different spray conditions. The powders are a nanocrystalline (Nanocarb), a near-nanostructured powder (Infralloy) containing a proprietary additive aimed at retarding grain growth, and multimodal (mixed micro and nano) powder (Nanomyte). HVOF spray conditions were stoic...
Nanoceria (i.e., CeO2 nanoparticles) fuel additives have been used in Europe and elsewhere to improve fuel efficiency. Previously we have shown that the use of a commercial fuel additive Envirox™ in a diesel-powered electricity generator reduced emissions of diesel exhaust particle (DEP) mass and other pollutants. However, such additives are currently not permitted for use in on-road vehicles i...
This work shows the synthesis of a catalyst based on functionalization octaphenyl polyhedral oligomeric silsesquioxanes with sulfonic groups (H-Sulfo-POSS) and its performance in acetalization glycerol to yield biobased fuel additive.
Ethanol could suddenly become the gasoline additive of choice in America. As policymakers debate the future path of U.S. energy policy, they face added concerns for public safety and America’s growing dependence on foreign oil. The outcome of these debates could spell the end for MTBE (methyl tert i a ry butyl ether) as a fuel additive—and have important implications for the future of the ethan...
Over 2 million military and civilian personnel per year (over 1 million in the United States) are occupationally exposed, respectively, to jet propulsion fuel-8 (JP-8), JP-8 +100 or JP-5, or to the civil aviation equivalents Jet A or Jet A-1. Approximately 60 billion gallon of these kerosene-based jet fuels are annually consumed worldwide (26 billion gallon in the United States), including over...
One way to improve fuel efficiency in today’s jet aircraft engines is to create an environment for higher operating temperatures and speeds. New and improved lubricants and bearing materials must be developed to remain stable in these elevated operating temperatures. Three lubricants, with varying amounts of tricresyl phosphate added as an anti-wear/extreme pressure additive were tested on two ...
With the way cleared for increased use of the fuel additive methylcyclopentadienyl manganese tricarbonyl (MMT) in the United States, the issue of possible public health impacts associated with this additive has gained greater attention. In assessing potential health risks of particulate Mn emitted from the combustion of MMT in gasoline, the U.S. Environmental Protection Agency not only consider...
