## 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.

## Claims

### Claim 1

A coke manufactured from coal, wherein the coke comprises:
an oblong shape,
a sulfur content less than 1.0%,
a moisture content of at least 1.0%,
a fixed carbon content of at least 80%,
an ash content between 5-12%,
a width of at least 3 inches, and
a length:width ratio of at least 1.5.

### Claim 2 (depends on 1)

The coke of claim 1, wherein the length:width ratio is at least 2.0.

### Claim 3 (depends on 1)

The coke of claim 1, wherein the coke has a length between 2 and 36 inches and the width is between 3 and 12 inches.

### Claim 4 (depends on 1)

The coke of claim 1, wherein the coke has a length of at least 4 inches.

### Claim 5

A population of coke products produced from a single production process or from a single oven, wherein the population of coke products is manufactured from coal, wherein at least 30% of the total coke has an oblong shape, and wherein individual ones of the coke products have:
a sulfur content less than 1.0%,
a moisture content of at least 1.0%,
a fixed carbon content of at least 80%,
an ash content between 5-12%,
a length between 2 and 36 inches,
a width between 3 and 12 inches, and
a length:width ratio of at least 1.1.

### Claim 6 (depends on 5)

The population of coke products of claim 5, wherein the coke products are produced by a horizontal oven.

### Claim 7

A coke manufactured from coal, wherein the coke has:
an oblong shape,
a sulfur content less than 1.0%,
a moisture content of at least 1.0%,
a fixed carbon content of at least 80%,
an ash content between 5-12%,
a length:width ratio of at least 1.5, and
a Coke Reactivity Index (CRI) of at least 20%.

### Claim 8 (depends on 1)

The coke of claim 1, wherein the fixed carbon content is at least 90%.

### Claim 9 (depends on 1)

The coke of claim 1, wherein the coke has a Coke Reactivity Index (CRI) of at least 20%.

### Claim 10 (depends on 1)

The coke of claim 1, wherein the moisture content is between 1-10%.

### Claim 11 (depends on 5)

The population of coke products of claim 5, wherein individual ones of the coke products have a Coke Reactivity Index (CRI) of at least 20%.

### Claim 12 (depends on 5)

The population of coke products of claim 5, wherein dimensions of the coke products are statistically distributed.

### Claim 13 (depends on 7)

The coke of claim 7, wherein the fixed carbon content is at least 85%.
