Abstract
High quality coke products made in horizontal ovens such as heat recovery, non-recovery or Thompson ovens from an optimized coal blend. The coke products have unique properties such as an oblong shape and improved Coke Strength after Reaction (CSR) and Coke Reactivity Index (CRI) properties.
Claims14
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 15% and 40%, and a sulfur content less than 1.0%.
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 5% and 60%, and, a fixed carbon content at least 80%.
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 15% and 40%, and an ash content less than 10%.
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 15% and 40%, and, a volatile matter (VM) content of less than 2%.
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 15% and 40%, and a moisture content between 1% and 10%.
A coke having a hydraulic diameter (Dh) greater than the actual diameter of the coke, wherein the coke has a Coke Reactivity Index (CRI) between 20-45%, a Coke Strength after Reaction (CSR) between 5% and 60%, and a gray or light gray color.
