Formic acid receives attention from a candidate for chemical hydrogen storage due to its easily decomposing characteristics to hydrogen and CO2. The CO2-based formic acid production process, which produces formic acid from CO2 and hydrogen, is being investigated as a sustainable alternative to the conventional formic acid production process. The aim of formic acid purity is 99 wt. % for the utilization of a hydrogen carrier. Notably, the CO2 hydrogenation reaction occurs in a trickle bed reactor, which has a high complexity of multiphase reaction. In addition, the thermodynamic data of certain components not found in the database are estimated by the group contribution method and the COSMO-RS package. The modeling of the reactor is conducted by MATLAB, and the CO2-based formic acid process is evaluated by techno-economic analysis and CO2 life cycle assessment based on the mass and energy balance of the simulation results. |
