Microwave pyrolysis of Laminaria digitata to produce unique seaweed-derived bio-oils

Integrated bioethanol and protein production from brown seaweed Laminaria digitata.

A wild-growing glucose-rich (i.e. 56.7% glucose content) brown seaweed species Laminaria digitata, collected from the North Coast of Denmark in August 2012, was used as the feedstock for an integrated bioethanol and protein production. Glutamic acid and aspartic acid are the two most abundant amino acids in the algal protein, both with proportional content of 10% in crude protein. Only minor pr...

Rheological Characterization of Bio-Oils from Pilot Scale Microwave Assisted Pyrolysis

Hydrothermal liquefaction of Litsea cubeba seed to produce bio-oils.

Hydrothermal liquefaction (HTL) of Litsea cubeba seed was conducted over different temperature (250-350°C), time (30-120 min), reactor loading (0.5-4.5 g) and Na2CO3 loading (0-10 wt.%). Temperature was the most influential factor affecting the yields of product fractions. The highest bio-oil yield of 56.9 wt.% was achieved at 290°C, 60 min, and reactor loading of 2.5 g. The presence of Na2CO3 ...

The Chemical Characterization of Woody Biomass-Derived Pyrolysis Oils

Kinetics modeling of alginate alkaline extraction from Laminaria digitata.

Alginates being depolymerized during their alkaline extraction, reducing extraction time could help producing higher rheological quality alginates. The purpose of the present work is to study fresh Laminaria digitata destructuration during alkaline extraction and its link to extraction kinetics. Both alginate extraction yield and mean diameter of algae particles were followed for different valu...
