Calcination - Wikipedia

The calcination process normally takes place at temperatures below the melting point of the product materials. Calcining is often confused with Sintering and Annealing process and indeed there is some conceptual overlap in these. Calcining is generally used more broadly than simply removing CO2 from carbonates.

CN104555982A - Method for calcining high sulfur petroleum ...

The invention discloses a method for calcining high sulfur petroleum coke. The calcining method comprises the following steps: adding the high sulfur petroleum coke in a pot calciner, and performing high-temperature calcining on the high sulfur petroleum coke at the calcination temperature of 1350 to 1550 DEG C, wherein the desulfurization rate of the high sulfur petroleum coke is 42-72 percent.

Calcining - Oxbow

Calcining. Overview. Calcined petroleum coke's nearly pure quality makes it ideal for use by the aluminum industry, which accounts for nearly 75 percent of the world's calcined coke consumption. For every pound of aluminum produced, about 0.4 pounds of carbon anode are consumed. Oxbow is the largest and most diversified producer and marketer of ...
