  • Patent number: 4306941
    Abstract: A dry coke quenching process comprises the steps of preheating a coke from a coke oven to a temperature of not lower than 1200.degree. C. by way of burning over its layer a combustible gas mixed with heated air, cooling the coke first to a temperature of not lower than 700.degree. C. with a mixture of hydrocarbons and water vapor, and then with an inert gas to a temperature of from 200.degree. to 250.degree. C.An apparatus for effecting the process of the invention comprises a chamber lined from inside with refractory brick and provided with a means for introducing a combustible gas and heated air to the upper part of the chamber and for discharging combustion gases therefrom. Provided in the middle part of the chamber are means intended for a heated mixture of hydrocarbons and water vapor to pass in therethrough and for a flow of the resultant gas containing hydrogen and carbon monoxide to escape therethrough.

  • Patent number: 4211607

C. by way of burning over its layer a combustible gas mixed with heated air, cooling the coke first to a temperature of not lower than 700.degree. C. with a mixture of hydrocarbons and water vapor, and then with an inert gas to a temperature of from 200.degree. to 250.degree. C.In the course of operation, coke, heated to a temperature of not lower than 1200.degree. C., is passed to the middle part of a chamber wherein a flow of a gas-steam mixture heated to a temperature of up to 700.degree. C. is introduced in countercurrent relation to the flow of coke. Resulting from the process of conversion of hydrocarbons with water vapor is gas containing hydrogen and carbon monoxide. The blast-furnace coke with a temperature of not lower than 700.degree. C. is passed from a middle part of the chamber to a lower part thereof wherein it is cooled to a temperature of 200.degree. to 250.
