A general relationship between the kinetic parameters for the gasification of coal chars with CO2 and coal type

A general relationship between the kinetic parameters for gasification of coal char with CO2 and coal properties is presented. Based on the analysis of the reason why there is no relationship between the kinetic parameters and coal type in previous investigations, a new idea for gasification kinetics has been put forward, and experiments showed that the gasification kinetic parameters for C+CO2→2CO really exhibit a unified relationship with coal type.
