Coke gas is a combustible gaseous by-product generated during the industrial production of coke from pit coal.
How is Coke Gas Produced?
This versatile gas is created through a process known as high-temperature dry distillation of coking coals. This industrial process occurs in the absence of oxygen, where coal is heated to extreme temperatures, causing it to break down and release various volatile components, including coke gas.
Key Components of Coke Gas
Coke gas is primarily composed of hydrogen and methane, along with smaller quantities of other gases. The exact proportions can vary, but its main constituents are vital to understanding its properties and potential uses.
Component | Typical Concentration |
---|---|
Hydrogen | 50-60% |
Methane | 15-50% |
Carbon Monoxide | Small percentage |
Carbon | Small percentage |
Nitrogen | Small percentage |
