A Reaction Kinetic Study of CO 2 Gasification of Petroleum Coke, Biomass and Mixture

Characteristics of Char- gasification for petroleum coke, biomass and mixed fuels were compared in the temperature range of using TGA (Thermogravimetric analyzer). Kinetic constants with respect to reaction temperature were determined by using different gas-solid reaction models. Also activation energy (Ea) and pre-exponential factors () in each models were calculated by using Arrhenius equation and then were compared with experimental values to determine reaction rate equation for char- gasification. Reaction time for gasification decreased with an increase of reaction temperature. Also, the activation energy of gasification reaction for mixture with petroleum coke and biomass decreased with increasing biomass contents. This indicates that mixing with biomass could bring synergy effects on gasification reaction.
