  • Patent number: 9068123
    Abstract: A new approach to the production of coke. In this process multiple optimized value streams are produced from a coke facility located at mine mouth or locally at an existing plant. As part of the process, lower cost Indiana/Illinois Basin-type coals are blended with conventional metallurgical coals. The blending process is optimized to meet coke quality requirements and simultaneously to obtain a pyrolysis gas composition suitable for production of ancillary products including liquid transportation fuels, fertilizer, hydrogen, and electricity. By using lower cost Indiana/Illinois Basin coal it is possible to reduce net coal costs. This process provides a new direction and approach for the production of coke in the future that optimizes value over multiple product streams while reducing both business and technological risk.

  • Patent number: 7611609
    Abstract: A method for producing non-recovery/heat recovery coke may include the steps of providing a container, disposing a volume of loose coal into the container such that a vertical dimension of the volume of loose coal in the container is smaller than a horizontal dimension of the volume of loose coal, applying a force to the coal in the container to produce a volume of compacted coal having a substantially uniform density which is larger than that of the loose coal, disposing the compacted coal into a non-recovery/heat recovery type oven, and heating the compacted coal to produce coke. The method may also include the steps of providing a container, and moving the non-recovery/heat recovery coke mass from the oven at a substantially constant elevation to the container, quenching the coke mass in the container to produce a quenched coke mass, and removing the quenched coke mass from the container.
