Abstract Reactivities of peat char have been measured in CO 2 –N 2 gas mixtures at temperatures ranging from 600°C and 900°C and pressures of up to 9.1 MPa using a fixed bed placed in a flow reactor. A semi‐empirical kinetic expression is presented which includes the temperature, CO 2 pressure and variation in the specific area of the substrate. An Arrhenius equation is used to obtain an activation energy of 99.1 kJ/mol for the gasification process.
