A study of microwave-assisted extraction of lipid from three algal species in 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIM][HSO4]), an imidazolium-based ionic liquid, was performed by evaluating the effects of microwave irradiation and ionic liquid on the extraction. The experimental results indicated that microwave irradiation could promote the extraction rate over 15 times for Chlorella sorokiniana,...
Porous cellulose beads (CBs) were prepared using ionic liquid as solvent and then further modified using different reagents which were ethylenediamine (EDA), diethylenetriamine (DETA), triethylene tetramine (TETA) and 4-aminostyrene (AST). These CBs were used as carrier for immobilization of H3PW12O40 (HPW). The immobilized catalysts were characterized by FT-IR, scanning electron microscopy, XRD,...
A negative pressure cavitation–microwave assisted extraction technique (NMAE) was first applied on extraction of seed oil from yellow horn. The operating conditions were optimized by a Box–Behnken design (BBD) test. Under the optimal conditions, the yield of yellow horn oil seed can reach 52±1%. The extraction kinetics of the NMAE method and soxhlet extraction (SE) method were also investigated. The...
In this contribution, we confirmed that aviation fuels could be synthesized directly from microalgae lipids in water over a Pt/C catalyst without additional hydrogen. After decarboxylation at 330 and 370°C for 120min, the oxygen content in the microalgae lipids was significantly reduced and the heating value of produced aviation fuels was greatly increased. The reaction mechanism of direct decarboxylation...
