Abstract

A new approach to the production of coke. In this process multiple optimized value streams are produced from a coke facility located at mine mouth or locally at an existing plant. As part of the process, lower cost Indiana/Illinois Basin-type coals are blended with conventional metallurgical coals. The blending process is optimized to meet coke quality requirements and simultaneously to obtain a pyrolysis gas composition suitable for production of ancillary products including liquid transportation fuels, fertilizer, hydrogen, and electricity. By using lower cost Indiana/Illinois Basin coal it is possible to reduce net coal costs. This process provides a new direction and approach for the production of coke in the future that optimizes value over multiple product streams while reducing both business and technological risk.
