Green bio-oil extraction for oil crops

Terpenes as green solvents for extraction of oil from microalgae.

Herein is described a green and original alternative procedure for the extraction of oil from microalgae. Extractions were carried out using terpenes obtained from renewable feedstocks as alternative solvents instead of hazardous petroleum solvents such as n-hexane. The described method is achieved in two steps using Soxhlet extraction followed by the elimination of the solvent from the medium ...

Green solvents and technologies for oil extraction from oilseeds

Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solven...

Pyrolysis of Seaweeds for Bio-oil and Bio-char Production

A pyrolysis study on a species of brown algae Saccharina japonica was carried out in a fixed-bed reactor. The yields of bio-oil and bio-char obtained at 450 C were 47 % and 33 %, respectively. The raw S, japonica, ethanol and acid pretreated samples and the resulting pyrolysis products were also characterized with respect to proximate and ultimate analysis, and higher heating value. The crude b...
