Abstract: 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.

Abstract: Process for producing activated carbon, preferably high surface area activated carbon, from inexpensive cellulosic precursors, such as paper, by pretreating the cellulosic precursor with an activating agent, such as phosphoric acid, followed by carbonization in an inert atmosphere at an elevated temperature to produce activated carbon. The activated carbon can be further activated to increase its surface area by heating it in an oxidizing atmosphere at an elevated temperature to yield activated carbon having a surface area of at least 100 m.sup.2 /g.
