## Abstract

A method is disclosed, for producing coke in which at least a first and second source of carbonaceous materials are introduced as feedstock into a mixer. The materials are mixed into a single feedstock, and the single feedstock is analyzed to determine its coking feasibility. The single feedstock is pyrolyzed in a pyrolyzer to produce at least a coke material and a gaseous by-product. At least a portion of the gaseous by-product is used outside of the pyrolyzer. Other embodiments are also disclosed.

## Claims

### Claim 1

A method for producing coke comprising:
introducing a first source of carbonaceous material as a first feedstock into a mixer;
introducing a second source of carbonaceous material as a second feedstock into the mixer;
mixing at least the first source of carbonaceous material and the second source carbonaceous materials into a single feedstock of carbonaceous materials;
pyrolyzing said single feedstock in a pyrolyzer to produce coke material;
harnessing a gas by-product from said pyrolyzing, the gas by-product being utilized in the pyrolyzer to provide energy to the pyrolyzer, the gas by-product being analyzed to determine if excess gas by-product is provided from the pyrolyzer and, if so, the excess gas by-product being supplied to an energy provider outside of the pyrolyzer; and
treating said gas before supplying at least a portion of it to the energy provider outside of the pyrolyzer.

### Claim 2 (depends on 1)

The method of claim 1 wherein the first source of carbonaceous material is coal fines.

### Claim 3 (depends on 1)

The method of claim 1 wherein the second source of carbonaceous material is coke waste fines.

### Claim 4 (depends on 1)

The method of claim 1 wherein the third source of material is added to the mixture.

### Claim 5 (depends on 1)

The method of claim 1 wherein said pyrolyzing the single feedstock of materials comprise the act of producing a metallurgical coke.

### Claim 6 (depends on 1)

The method of claim 1 wherein the predetermined material composition is selected from the group consisting of
a particular composition;
a particular reactivity;
a particular shape;
a particular by-product generation;
a particular size;
a particular strength; and
a particular heating value.

### Claim 7

A method for producing coke comprising:
mixing at least a first carbonaceous material and a second carbonaceous material into a single feedstock of carbonaceous materials;
determining coking feasibility of said single feedstock of carbonaceous materials;
modifying said single feedstock into a predetermined material composition; and
pyrolyzing said customized single feedstock in a pyrolyzer to produce coke material and coke by-products that are used outside of the pyrolyzer, the gas by-product being utilized in the pyrolyzer to provide energy to the pyrolyzer, the gas by-product being analyzed to determine if excess gas by-product is provided from the pyrolyzer and, if so, the excess gas by-product being supplied to an energy provider outside of the pyrolyzer.

### Claim 8 (depends on 7)

The method of claim 7 wherein the predetermined material composition is selected from the group consisting of
a particular shape;
a particular by-product generation;
a particular composition;
a particular reactivity;
a particular size;
a particular strength; and
a particular heating value.

### Claim 9 (depends on 7)

The method of claim 7 wherein the coke by-products that are used outside the pyrolyzer include gas.

### Claim 10

A method for producing coke comprising:
introducing a first source of carbonaceous material as a first feedstock into a mixer;
introducing a second source of carbonaceous material as a second feedstock into the mixer;
mixing at least the first source of carbonaceous material and the second source carbonaceous materials into a single feedstock of carbonaceous materials;
analyzing said single feedstock of carbonaceous materials to determine coking feasibility of the single feedstock of carbonaceous material;
customizing said single feedstock into a predetermined material composition; and
pyrolyzing said single feedstock in a pyrolyzer to produce at least a coke material and a gaseous by-product, the gaseous by-product being utilized in the pyrolyzer to provide energy to the pyrolyzer, the gaseous by-product being analyzed to determine if excess gas by-product is provided from the pyrolyzer and, if so, the excess gas by-product being supplied to an energy provider outside of the pyrolyzer.

### Claim 11 (depends on 10)

The method of claim 10 wherein the gaseous by-product is treated to remove impurities.

### Claim 12 (depends on 10)

The method of claim 10 wherein the single feedstock of carbonaceous material is modified into a predetermined material composition selected from the group consisting of a particular reactivity, a particular shape, a particular size, a particular composition, a particular strength, a particular heating value, and a particular size.
