Worldwide annual consumption of industrial carbon was about 25 × 10⁶ t/a in 1994, excluding metallurgical coke (see Table 6.1.2.5 and Figure 6.1.2.10); main products are carbon anodes and carbon black. Two thirds of this margin is calcinate from petroleum coke [6, 7, 27, 28].

Figure 6.1.2.11 World market profile for petroleum coke 2010.

In 2014, the production of calcined petroleum coke is expected to be 29 × 10⁶ t/a with 74% about 21.5 × 10⁶ t/a being used for aluminum anodes.

Figure 6.1.2.11 shows the world market profile for petroleum coke in 2010 [6, 7, 29]. The relations are the same as now: more than 70% of petroleum coke is burned as fuel.
