A study on deoxygenation of oleic acid over Ce0.6Zr0.4O2 catalysts depending on the reaction time |
| 초록 |
Ce0.6Zr0.4O2 catalyst was prepared by a co-precipitation method for deoxygenation (DO) of oleic acid in hydrogen environment (20% H2/N2 condition). In this study, reaction time was systematically varied to optimize diesel yield at a reaction temperature of 300 oC. When the reaction time was 3 h, C15 & C17 hydrocarbons were the major products. As the reaction time increased from 3 to 12 h, the portions of C9 ~ C13 and C17 hydrocarbons increased while C15 selectivity decreased. The conversion and selectivity increased as the reaction time increased. Although the conversion and selectivity were increased, the increase of reaction time did not show totally good points because side reaction (cracking) also occurred. For the production of gasoline, longer contact time should be considered to maximize yield. Therefore, shorter contact time should be chosen to optimize diesel yield. |
