Abstract

Characteristics of Char-CO₂ gasification for petroleum coke, biomass and mixed fuels were compared in the temperature range of 1,100∼1,400 ℃ 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 (K₀) in each models were calculated by using Arrhenius equation and then were compared with experimental values to determine reaction rate equation for char-CO₂ gasification. Reaction time for CO₂ gasification decreased with an increase of reaction temperature. Also, the activation energy of CO₂ 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 CO₂ gasification reaction.
