Sulfation of metal-organic framework (MOF) nanocatalyst for esterification of oleic acid with methanol to produce biodiesel
نویسندگان
چکیده
Background: Metal-organic frameworks (MOFs) represent tremendous potential as heterogeneous catalyst in renewable energy production. In this study, biodiesel production using the modified MOF nanocatalyst was investigated esterification reaction. Methods: prepared solvothermal method and through sulfation process. The nanocatalysts characterized by XRD, FT-IR, FE-SEM, TEM, N2 adsorption-desorption, NH3 -TPD techniques. performance of evaluated reaction free fatty acid (FFA) at different operating conditions. Results: results showed high crystallinity, appropriate textural properties (995.6 m2 g-1), well-adjusted acidity, hydrophobicity. degree 4 cc g-1 resulted best nanocatalyst, which led to highest FFA conversion (97%) optimal conditions: methanol ratio 10:1, 3wt.% 160 °C, 6 hours. Surprisingly, developed had a great reusability while reduction only 8% after six sequence cycles. Conclusion: These proved capability produce biodiesel.

Controlled ripening of climacteric fruits, such as bananas and avocados, is a critical step to provide consumers with high-quality products while reducing postharvest losses. Prior to ripening, these fruits can be stored for an extended period of time but are usually not suitable for consumption. However, once ripening is initiated, they undergo irreversible changes that lead to rapid quality l...
متن کاملPost-synthesis modification of a metal-organic framework to form metallosalen-containing MOF materials.
A series of metallosalen-based metal-organic frameworks (MOFs) have been prepared by the post-synthesis modification of Mn(III)SO-MOF, a Mn(3+)(salen)-based MOF. Treatment of Mn(III)SO-MOF with H(2)O(2) effects the removal of the Mn(3+) ions from the salen struts, which can then be remetalated with a variety of metal precursors to form isostructural MSO-MOF materials. The presence of the new me...
