  • Treating-high asphaltene fuel oils
    Patent number: 4479805
    Abstract: A process for the treatment of asphaltene-bearing fuel oils to reduce the amount of acid-smut in stack gas often emitted during the combustion of such fuels.

Generally, the treated oil will have a majority of asphaltene particles with a diameter of less than 2 microns, and substantially all asphaltene particles with a diameter of 7 microns or less. The processed fuel will also have uniformly dispersed asphaltene particles.

  • Process for forming novel silver powder composition
    Patent number: 4463030
    Abstract: A novel silver powder paint composition characterized by a very low fusion, or film-forming temperature, probably assignable to the relatively small amount of oxides or other undesirable occulsions within coatings formed of the powder. The invention also relates to a new process for forming such a powder; the process is believed to involve the formation of a fatty-acid silver reaction product of the surface on the silver powder before it is subjected to fusion into a metallic coating. During fusion the decomposing reactant seems to act as a flux aiding the formation of a metal film of superior appearance and strength.
