AI Technical Summary
In existing biomass high-density fuel production processes, hydrophobic catalysts have insufficient acid strength and high-temperature resistance, and catalyst separation and recovery are difficult, affecting reaction conversion rate and selectivity.
Using Fe3O4@SiO2 microspheres as a support, a superhydrophobic strong acid magnetic catalyst was prepared by grafting with perfluorosulfonic acid. Combined with hydrothermal reaction, a mesoporous structure was formed, achieving superhydrophobicity, oleophilicity, and high temperature resistance of the catalyst.
The catalyst exhibits high activity, selectivity, and good cycle stability in the synthesis reaction of biomass high-density fuel precursors. It is easy to separate magnetically and is suitable for Aldol condensation and alkylation reactions, with high yield and good industrial application potential.
