    摘要: A process for treating high sulfur petroleum coke to inhibit puffing is disclosed wherein particles of the petroleum coke are contacted, in the absence of a binder, with a compound containing an alkali or alkaline earth metal selected from the group consisting of sodium, potassium, calcium and magnesium, at an elevated temperature above that at which the alkali or alkaline earth metal compound begins to react with carbon, but below the temperature at which the coke particles would begin to puff in the absence of the compound. The coke particles are maintained at the elevated temperature for a sufficient period of time to permit the reaction to proceed and allow products of reaction to penetrate into the particles and form an alkali-or alkaline-earth-metal-containing deposit throughout the mass of the particles; and then cooling the so-treated coke particles.

    摘要: A rotary hearth calciner for treating petroleum cokes with a puffing inhibitor has a horizontal or inwardly sloping hearth floor rotatable around a vertical axis for receiving particles of coke to be calcined and a central opening in the hearth floor for discharging the coke into a soaking pit. A water cooled, refractory covered feed pipe extending downward into the calciner interior has an inlet for connection to a source of petroleum coke puffing inhibitor and an outlet near the edge of the hearth central floor opening for adding the puffing inhibitor to the coke as the coke is discharged from said hearth floor. The feed pipe outlet is approximately at or below the level of the hearth floor to reduce loss of inhibitor in gas flow above the hearth floor. A puffing inhibitor such as sodium carbonate is supplied by a screw feed mechanism to the feed pipe to add the puffing inhibitor at a desired rate for reaction with the coke. The coke is normally maintained in the soaking pit for about 30 minutes at 1200.degree.-1400.degree. C.
