Due to worldwide restrictions on gaseous sulfur emissions in industrialized nations, and the overabundance of fuel grade coke, the price of high sulfur petroleum coke is expected to remain very low relative to other fuel and carbon sources. The LS-RIOR process is the only process now available that can utilize this inexpensive source of energy to convert iron ore fines to low sulfur sponge iron suitable for use as electric arc furnace (EAF) feedstock or basic oxygen furnace coolant. The key to this unique capability is in the LS-RIOR pelletizing process, which produces highly reactive pellets from iron ore fines using petroleum residuum as binder. As in the case with coke, petroleum residue is predicted to be in ample supply through the 20th century. LS-RIOR pellets can be easily desulfurized in the rotary kiln, while conventional iron ore pellets, which use bentonite binder, cannot be used to produce low sulfur sponge iron when high sulfur reductant is employed.
