  • Process for the production of high purity coke from coal
    Patent number: 4943367
    Abstract: High purity coke particularly suited to the production of anodes for aluminium smelting is produced by an integrated process that includes flash pryolysis and delayed coking. In the integrated process, flash pyrolysis of carbonaceous materials such as coal, oil shale or tar sand is operated under conditions that maximize the production of tar suitable for coking, and the delayed coking is operated under conditions that maximize the coke yield, and intermediate products may be recycled to enhance overall efficiency.
