| Although coke is an absolute essential part of iron making from ore and foundry processes, recently there was a shortfall of 5.5 million tons of coke per year in the United States. This shortfall resulted in increased imports, drastic increases in coke prices, and market volatility. Purdue University researchers have developed an optimization algorithm for coke that could reduce annual coal fuel costs by up to 10 percent while allowing consideration for overlooked byproducts that now have revenue potential. This cost reduction is obtained through the use of less costly, lower heat content, high-sulfur coal from sources such as the Illinois Basin. Previously, the high-sulfur content was a detriment for coal users and almost made this coal unusable due to its undesirable trait of forming hydrogen sulfide during the pyrolysis process. This technology can also place a value on this sulfur content. With modern technology and the current economic drivers for alternative energy, pyrolysis gas has a multitude of uses including the production of electricity, liquid transportation fuels, fertilizer, and hydrogen. The value of lower-grade coal alternatives can now be identified, and better yet, maximized. Advantages: -Reduced cost of coal through utilization of Illinois Basin coal -Enhanced revenue streams Potential Applications: -Materials -Manufacturing |
