  • Process For The Desulfurization Of Petroleum Coke

    Delayed coke especially manufactured for use in graphite can be effectively desulfurized by calcining in a hydrocarbon fuel-fired calciner in the temperature range of 2700.degree. F. to 2900.degree. F. without adversely affecting the strength of the coke or the coefficient of thermal expansion of the graphitized coke.

  • Method Of Producing Petroleum Coke Calcinate

    Green petroleum coke is indirectly dried, then calcined in a cylindric rotary kiln and indirectly cooled utilizing a one-way gas flow in the system. Most of the dust in the vapor from the drying step is directly burned in a steam boiler whose off-gases are used to heat the dryer. Any residual dust in the gas is collected in an electro-filter.
