Major Field of Science: | Natural Sciences | Field Category: | Chemical Sciences | Keywords: | Green diesel;Catalyst deactivation;Selective deoxygenation;Computational fluid dynamics (CFD) | Issue Date: | Jun-2021 | Source: | Catalysts, 2021, vol. 11, no. 6, articl. no. 747 | Volume: | 11 | Issue: | 6 | Journal: | Catalysts | Abstract: | For the first time, a fully comprehensive heterogeneous computational fluid dynamic (CFD) model has been developed to predict the selective catalytic deoxygenation of palm oil to produce green diesel over an Ni/ZrO2 catalyst. The modelling results were compared to experimental data, and a very good validation was obtained. It was found that for the Ni/ZrO2 catalyst, the paraffin conversion increased with temperature, reaching a maximum value (>95%) at 300◦CHowever, temperatures greater than 300◦C resulted in a loss of conversion due to the fact of catalyst deactivation. In addition, at longer times, the model predicted that the catalyst activity would decline faster at temperatures higher than 250◦C. The CFD model was able to predict this deactivation by relating the catalytic activity with the reaction temperature. | URI: | https://hdl.handle.net/20.500.14279/22964 | ISSN: | 20734344 | DOI: | 10.3390/catal11060747 | Rights: | © 2021 by the authors.
