  • Patent number: 4162143
    Abstract: The present invention is directed to water-in-oil type fuel oil emulsions which are particularly useful in firing boilers in ships, locomotives and industrial power plants. Furthermore, the invention is directed to aqueous particulate slurries dispersed in fuel oil. Specifically, the invention is directed to aqueous/oil slurries of combustible or non-combustible particulate having improved burning characteristics. Of specific interest are stable aqueous/oil slurries of coal dust. These emulsions and slurries are achieved through the use of a novel blend of cationic, nonionic and anionic surfactants to which the invention is also directed.

  • Patent number: 4159913
    Abstract: The deposition of a carbonaceous coating on the surface of a particulate siliceous filler by catalytic thermal decompositon of an organic compound, to improve the value of the said filler in organic polymer compositions, is difficult with some varieties of siliceous filler. The invention is based on the treatment of the initial siliceous filler with a solution of an ammonium salt or a salt of an organic base to displace alkali metal ions, which are believed to inhibit the desired catalytic decomposition. The treatment is carried on to reduce the alkali metal ions (especially sodium) to an acceptably low level, preferably below about 500 ppm. The treatment is especially applicable to precipitated silica fillers.
