Global Demand for Coke and Hot Metal Source: US Geological Survey • Even though Steel Companies driving down coke/thm through technology and alternate reductants, coke demand still increasing • Increasing demand for coking coals expected September 2011 SunCoke Energy 6
Alternate Reductants for Coke Replacement • Increased use of PCI and other reductants to replace coke in Blast Furnaces • As high as 30-40% of blast furnace coke has been replaced by alternate reductants like PCI • Alternate reductants could potentially make up as much as 50% of the total reductant • As alternate reductants like PCI increase, higher quality coke needed: – Supports the burden (about 50% of total reductant) – Distributes gases • Will drive demand for larger and stronger coke!
