  • Integrated two-stage coal liquefaction process
    Patent number: 4536275
    Abstract: This invention relates to an improved two-stage process for the production of liquid carbonaceous fuels and solvents from carbonaceous solid fuels, especially coal.
    Type: Grant
    Filed: March 7, 1984
    Date of Patent: August 20, 1985
    Assignee: International Coal Refining Company
    Inventors: James C. Bronfenbrenner, Ronald W. Skinner, Samuel Znaimer
  • Coal liquefaction process
    Patent number: 4510040
    Abstract: This invention relates to an improved process for the production of liquid carbonaceous fuels and solvents from carbonaceous solid fuels, especially coal.The claimed improved process includes the hydrocracking of the light SRC mixed with a suitable hydrocracker solvent. The recycle of the resulting hydrocracked product, after separation and distillation, is used to produce a solvent for the hydrocracking of the light solvent refined coal.
    Type: Grant
    Filed: November 7, 1983
    Date of Patent: April 9, 1985
    Assignee: International Coal Refining Company
    Inventors: Ronald W. Skinner, John C. Tao, Samuel Znaimer
  • Two-stage coal liquefaction process
    Patent number: 4491511
    Abstract: An improved SRC-I two-stage coal liquefaction process which improves the product slate is provided. Substantially all of the net yield of 650.degree.-850.degree. F. heavy distillate from the LC-Finer is combined with the SRC process solvent, substantially all of the net 400.degree.-650.degree. F. middle distillate from the SRC section is combined with the hydrocracker solvent in the LC-Finer, and the initial boiling point of the SRC process solvent is increased sufficiently high to produce a net yield of 650.degree.-850.degree. F. heavy distillate of zero for the two-stage liquefaction process.
