Filed:

Sep 8, 2009

Appl. No.:

12/555496

Inventors:

Robert A. Kramer - Crown Point IN, US
Libbie S. W. Pelter - Schereville IN, US

Assignee:

Purdue Research Foundation - West Lafayette IN

International Classification:

C10B 47/00
C10B 53/00

US Classification:

201 1, 201 4, 201 24, 201 29

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.
