  • Cellular solvent refined coal and methods for making same
    Patent number: 4128401
    Abstract: Described is a cellular form of solvent refined coal characterized by a decreased density enabling it to float on water. Various methods are presented for introducing cells throughout the coal including the use of cell-forming agents; sintering; particle or gas dispersion; and leaching salts incorporated in the coal.
    Type: Grant
    Filed: May 4, 1977
    Date of Patent: December 5, 1978
