The increase in technologies has significantly increased the need for electricity in Indonesia. This escalation makes the expenditure of carbon emissions quite high. The carbon released into the atmosphere is one of the reasons a phenomenon called global warming is haunting us. There are several efforts considered and executed to decrease the amount of carbon emission, one of the methods is CO2 capture. Chemical Looping Combustion (CLC) unit is one of the promising technologies from a long time ago to help capture CO2 because combustion in CLC required the O2 to be separated from the air thus, it helps in capturing CO2. Along with it, a CLC is able to produce Hydrogen (H2) which is a non-carbon fuel to help suppress the carbon emission and to change to a carbon-free energy carrier. In this research, a CFD simulation and modeling will be executed. The simulation will be in cold-model to analyze the hydrodynamic of the system. After the simulation was conducted the result showed that the fluidized type bubbling had occurred in the system and the stability time the system needed also obtained. A comparison between experiment and simulation also conducted. The result shows that similar behaviors of granular happen in the process and the data agreed well with the experiment data regarding mass flow rate. The simulation results show the potential advantages of developing and optimizing hydrogen production in such a complex reactor system. However, a comprehensive hydrodynamics model coupling with the reaction kinetic, thermodynamic, and heat transfer constraints is necessary for the design of the reaction system. Hopefully, the research will be used to continue the research of CLC or the creation of CLC itself.
