SUMMARY:

Greenhouse gases emissions and their consequences are one of the main environmental problems faced today. To mitigate the impacts caused by this phenomenon, Brazil seeks to reduce CO2 emissions by 43% by 2030 in order to meet the Paris Agreement. To achieve this goal, it is possible to use techniques based on the principle of Carbon Capture and Storage, with Chemical Looping Combustion being one of these technologies. These processes are versatile in terms of the use of fuels in the three states of matter. As the growing valorization of glycerin in recent years represents about 10% of the amount of biodiesel generated, there is a need to relocate this by-product to other applications. Thus, this proposal aims to evaluate the feasibility of glycerin on Chemical Looping Combustion and provide its mathematical modeling. The crude glycerin solution will be synthesized considering water, methanol, sodium hydroxide and potassium hydroxide as the main contaminants. Two 2³ experimental designs will be applied: the first design for the operational conditions (O/C ratio, H2O/C₃H₈O₃ ratio and T_FR) and the second design will be applied for the contaminants using the best operational conditions determined by the previous experimental design. The gases generated after the combustion will be analyzed by SIEMENS/CALOMAT 6 (for the Fuel Reactor gases) and SIEMENS/ULTRAMAT 23 (for the Air Reactor gases) to determine the composition of the outlet flow. The mathematical modeling will be developed in Python (v3.7) in two stages: implementation of a mathematical model previously reported in the literature for gaseous fuels and implementation with adjustment of variables and parameters for liquid fuels. Based on the experimental results and on the implemented model, parameters will be estimated for the reaction kinetics involving glycerin.
