The interest in sustainable hydrocarbon-like biofuel production is increasing, and Fe/HMS catalyst has shown potential in efficiently producing diesel-range biofuel. The catalyst's performance is attributed to well-dispersed Fe in the hematite phase, interaction between Si-OH and Fe-O bonds, acidity, surface area, and pore size enhancements. This result indicates Fe/HMS catalyst as a potential DO catalyst for renewable hydrocarbon-like biofuel production.
The interest in the production of sustainable hydrocarbon-like biofuel is increasing due to the environmental issues such as global warming and uncertainty of crude oil prices. A series of Fe catalysts (5, 10, 40, and 100 wt% Fe) supported on the hexagonal mesoporous silica (HMS) were successfully prepared for the production of biofuel via deoxygenation (DO) reaction. In the DO reaction, the diesel range biofuel is produced in the absence of H2 and solvents. Interestingly, the 40 wt.%Fe/HMS catalyst exhibited the highest conversion and selectivity of 81.4 and 84.8%, respectively toward C8-C20 hydrocarbons-like biofuel at 380 degrees C for 2 h. This performance is closely related to the well-dispersed Fe in the hematite phase, along with the interaction between Si-OH and Fe-O bonds. The acidity, surface area, and pore size of Fe/HMS have improved the catalytic activity. This result demonstrates that the Fe/HMS catalyst is a potential DO catalyst for the production of renewable hydrocarbonlike biofuel.
