  • Process for producing synthetic caking coal and binder pitch
    Patent number: 4061472
    Abstract: A raw synthetic caking coal having a volatile matter content of 20 - 70%, H/C (atomic ratio) of 0.60 - 1.20 and a maximum fluidity of greater than 40 ddpm is produced by coking heavy hydrocarbons. Synthetic caking coal having a volatile matter content of 20 - 40%, H/C (atomic ratio) of 0.60 - 0.75, a maximum fluidity of greater than 40 ddpm and a Free-Swelling-Index of greater than 3 is produced from the raw synthetic caking coal by stripping said raw synthetic caking coal with steam or light hydrocarbons.

  • Process for producing synthetic coking coal and treating cracked oil
    Patent number: 4036736
    Abstract: Synthetic coking coal is produced by coking heavy hydrocarbons at a temperature greater than the temperatures which initiate cracking in the coker, and by removing the gaseous and liquid products from the coker at accelerated velocities. The thermally cracked oil produced in the coking reaction can be hydrodesulfurized to produce a low sulfur fuel oil.
