The use of fossil fuels has increased drastically since the Industrial Revolution and has increased CO2 emissions into the atmosphere. Carbon capture utilization (CCU) technology has recently received a lot of attention to convert captured CO2, as a renewable carbon feedstock, into products and store it permanently. In this study, the manufacture of Na2CO3 using a carbonator reactor as a CO2 absorber into NaOH solution. The method used is the carbonation method. This study studied the optimum conditions for the formation of sodium carbonate from CO2 and NaOH by reviewing the reaction kinetics (reaction rate constants and activation energy). Making Na2CO3 is done by varying the concentration of NaOH (20%, 30%, 50%, 60%, 70%) and reaction temperature (30℃, 40℃, 50℃, 60℃). Fixed variable reactor volume 250 ml and reaction time for 30 minutes. The results of this study indicate that the higher the concentration of NaOH and the temperature, the greater the value of the reaction rate, the greater the activation energy, the slower the reaction rate because the minimum energy for the reaction to occur is greater. In the XRF analysis of sodium carbonate, this research includes light (glass industry) and dense (detergent) types at temperatures of 40oC and 60oC.References
