چکیده انگلیسی


• Kinetic parameters evaluation for reactions in integrated catalytic adsorption gasification.
• Evaluation of parameters by minimizing error between experimental and modeling values.
• Model predicts well experimental gas composition at temperature, steam and adsorbent to biomass.
• Water gas shift is found to be non-sponatious reaction at 600–750 °C.
• Equilibrium constant moves away from equilibrium at 600–675 °C due to strong CO2 adsorption.

Integrated catalytic adsorption (ICA) gasification provides an efficient mean to produce hydrogen rich gas. This article presents the prospect of ICA steam gasification of palm kernel shell. The effect of temperature, steam to biomass ratio and adsorbent to biomass are investigated for H2, CO, CO2 and CH4 composition to determine kinetic parameters by minimizing the error between experimental and modelling results. Based on the evaluated kinetic parameters, the model predicts the product gas composition for the effect of temperature, steam to biomass ratio and adsorbent to biomass ratio. A significant fitting of model predicted values to the experimental results is achieved. Furthermore, it is also found that the water gas shift reaction is non-spontaneous and far away from the equilibrium at a temperature range of 600 °C–675 °C which may be due to strong CO2 adsorption reaction.
