Bio-Oil Production From the Pyrolysis of Blue-Green Algae for Sustainability Alternative Fuels


Pyrolysis experiments of blue-green algae (Arthrospira platensis) were carried out in a custom-built tube reactor to determine the pyrolysis conditions which was affected by the production of pyrolysis oil. The effects of process variables; the operating temperature (400-600 oC), raw material federate (0.4-3.0 kgh-1 ), particle size (150- 800 µm) and N2 flowing rate (50-250 ml min-1 ) were also investigated. The maximum bio-oil yield of 46.19 %wt. was obtained at a process conditions of 500 oC feed rate of 0.6 kgh-1 , N2 flow rate of 200 ml min-1 where using a feedstock by an average particle size of 500 µm. The oily and aqueous phase also were separated, the bio-oil yield was obtained and their characteristics were investigated using GC-MS technique and FT-IR also was confirmed the functional group of bio-oil which obtained of phenol, amide and carboxylic acid. The physico-chemical analysis shows that bio-oil that have a higher calorific value of 29.12 MJkg-1 promising an alternative fuels, whereas the high level of acidity of 46.78 mgKOH/g required an upgrading before used as a fuels.
