coal pyrolysis
Molecular formula :
CAS :

nature : it refers to coal thermal decomposition of gas, tar and other substances, and gradually coking process. Study coal pyrolysis method of the main characteristics of the process of pyrolysis gas precipitation changes in the speed, volatile dynamics of precipitation measured. Thermal decomposition process consists of two consecutive stages. The first stage is 350 ~ 550 ° C within and emit a large number of carbon, hydrogen and oxygen to the volatile compounds, mainly oil and coal tar. After 550 ° C for secondary pyrolysis, and about 700 ° C emergence of a second peak. Precipitation of gas is mainly methane and hydrogen.
