Abstract
Coal blends used to produce foundry coke products are disclosed herein. Coal blends can include first coals having a first volatile matter mass fraction less than or equal to a first threshold, and second coals having a second volatile mass fraction greater than or equal to a second threshold that is less than the second threshold. The coal blend can have an ash fusion temperature less than 2600° F. and an aggregated volatile matter mass fraction between 15% and 25%.
Claims25
A coal blend, comprising:
- first coals having a first volatile matter mass fraction less than or equal to a first threshold;
- and
- second coals having a second volatile matter mass fraction greater than or equal to a second threshold,
- wherein:
- the first threshold is less than the second threshold by at least 4.0%;
- an ash fusion temperature of the coal blend is less than 2600° F.;
- and
- the coal blend has an aggregated volatile matter mass fraction between 15% and 25%.
A coal blend, comprising:
- first coals having a first volatile matter mass fraction less than or equal to a first threshold;
- and
- second coals having a second volatile matter mass fraction greater than or equal to a second threshold,
- wherein:
- the first threshold is less than 21.0%;
- the second threshold is greater than 25.0%;
- and
- an ash fusion temperature of the coal blend is less than 2600° F.
A method of determining a coal blend for coke product production comprising:
- obtaining a plurality of coal parameters of first coals and second coals, wherein:
- the first coals have a first volatile matter mass fraction less than or equal to a first threshold;
- and
- the second coals have a second volatile matter mass fraction greater than or equal to a second threshold, wherein the first threshold is less than the second threshold by at least 4.0%;
- determining a plurality of coke product parameters based on the plurality of coal parameters;
- and
- based on the plurality of coke product parameters, determining a coal blend formulation for a coal blend comprising a combination of the first coals and the second coals.
