Overview of Coke Oven Gas
Summary:
How much do you know about coke oven gas? The following is introduced by coke oven manufacturers: coke oven gas, also known as coke oven gas. It refers to a combustible gas produced while producing coke and tar products after high-temperature carbonization in the coking oven, which is a by-product of the coking industry. Coke oven gas is a mixture, its yield and composition due to the quality of coking coal and coking process conditions vary, generally per ton of dry coal can produce coke oven gas 300~350 m3 (standard state). Its main components are hydrogen (55% ~ 60%) and methane (23% ~ 27%), and it also contains a small amount

Coke oven gas, also known as coke oven gas. It refers to a combustible gas produced while producing coke and tar products after high-temperature carbonization in the coking oven, which is a by-product of the coking industry.
Coke oven gas is a mixture, its yield and composition due to the quality of coking coal and coking process conditions vary, generally per ton of dry coal can produce coke oven gas 300~350 m3 (standard state). Its main components are hydrogen (55% ~ 60%) and methane (23% ~ 27%), and it also contains a small amount of carbon monoxide (5% ~ 8%), unsaturated hydrocarbons above C2 (2% ~ 4%), carbon dioxide (1.5 ~ 3%), oxygen (0.3~0.8%), and nitrogen (3% ~ 7%). Wherein hydrogen, methane, carbon monoxide, C2 and above unsaturated hydrocarbons are combustible components, and carbon dioxide, nitrogen and oxygen are non-combustible components.
Coke oven gas belongs to the middle calorific value gas, its calorific value is 17 ~ 19MJ per standard cubic meter, which is suitable for fuel and city gas of high temperature industrial furnace. Coke oven gas has high hydrogen content and is used for ammonia synthesis after separation. Other components such as methane and ethylene can be used as raw materials for organic synthesis.
Coke oven gas is a toxic and explosive gas, and the explosion limit in the air is 6% ~ 30%.
