The blending with lowquality coal is 15% maximum in the wet system, and it arrives to 30% in the dry configuration. By converting coke ovens (50 t/h capacity) from wet to dry, a reduction of over 130,000 t/year of CO 2 can be reached; this corresponds to 8% of net reduction of CO 2 emissions in the atmosphere.

Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of the coal blending and coking process.
