The water may be at a temperature above ambient.
Abstract:
A process for making cerium-containing oxide nanoparticles includes providing an aqueous reaction mixture containing a source of cerous ion, optionally a source of one or more metal ions (M) other than cerium, a source of hydroxide ion, at least one monoether carboxylic acid nanoparticle stabilizer wherein the molar ratio of said monoether carboxylic acid nanoparticle stabilizers to cerous ions is greater than 0.2, and an oxidant. The cerous ion is oxidized to ceric ion, thereby forming a product dispersion of cerium-containing oxide nanoparticles CeO2-δ, wherein δ has a value of about 0.0 to about 0.5. The nanoparticles may have a mean hydrodynamic diameter from about 1 nm to about 50 nm, and a geometric diameter of less than about 45 nm.

In addition, an improved jet fuel is provided, having from 1-10 wt % biomass-derived mesitylene added thereto, having improved carbon emission characteristics while maintaining required specifications. Further, an improved bio-fuel is provided, which may function as a replacement for conventional Jet A/JP-8 fuel and has lowered carbon emission specifications, the bio-fuel comprised of 75-90 wt % synthetic parafinnic kerosene (SPK) and 10-25 wt % mesitylene.
Abstract:
A method is described for reducing nitrogen oxides in the exhaust gas flow of combustion engines, especially a motor vehicle internal combustion engine, wherein an air/fuel mixture in the combustion chamber of the combustion engine is combusted in the presence of a fuel additive and, in the process, the fuel additive decomposes and the exhaust gas flow is guided through at least one catalyst arranged downstream of the combustion chamber. This method is characterized in that a fuel additive is used, which decomposes in the combustion chamber releasing ammonia and the exhaust gas flow containing ammonia is guided through at least one SCR catalyst arranged downstream of the combustion chamber to reduce the concentration of the nitrogen oxides contained therein. The method according to the invention is highly effective in reducing the nitrogen oxide content in the exhaust gas flow of a combustion engine without an exhaust gas aftertreatment system having to be expensively formed and the installation space having to be increased.
