焦化气的主要成分是氢气和甲烷，另外还含有少量的一氧化碳、C2以上不饱和烃、二氧化碳、氧气、氮气。

The main components of coking gas are hydrogen and methane, as well as small amounts of carbon monoxide, unsaturated hydrocarbons above C2, carbon dioxide, oxygen, and nitrogen.

　　焦化气，又称焦化气，是指用几种烟煤配制成炼焦用煤，在炼焦炉中经过高温干馏后，在产出焦炭和焦油产品的同时所产生的一种可燃性气体，是炼焦工业的副产品。

Coking gas, also known as coking gas, refers to a combustible gas produced by preparing several types of bituminous coal into coking coal, which is then subjected to high-temperature dry distillation in a coking furnace, while producing coke and tar products. It is a byproduct of the coking industry.

　　其中氢气、甲烷、一氧化碳、C2以上不饱和烃为可燃组分，二氧化碳、氮气、氧气为不可燃组分。

Among them, hydrogen, methane, carbon monoxide, and unsaturated hydrocarbons above C2 are combustible components, while carbon dioxide, nitrogen, and oxygen are non combustible components.
