| Popis: | A microscale-based electrochemical reactor was introduced for the reduction of CO 2 into CH 4 , CH 3 OH, H 2 , HCOOH and HCHO with the presence of ionic liquid BMIM-BF 4 (1-butyl-3-methylimidazolium tetrafluoroborate). Reduction of CO 2 was studied under various experimental conditions controlled by factors such as solvent concentration, microreactor height, and mean residence time of fluids in the microreactor. A mathematical model reflecting geometry and flow conditions inside the microreactor was developed to simulate the chemical reaction process. The parameters of the mathematical model were determined using an optimization process in which the best fit between the experimental data and the model prediction was achieved. The model describes the reactions containing substrate reactants (CO 2 and H 2 O) and final products (CH 4 , CH 3 OH, H 2 , HCOOH, and HCHO), which were measured throughout CO 2 reduction process experiments. |
