Distribution of Phenolic Compounds from Ulva Lactuca and Sargassum sp. via Slow-Pyrolysis

Abstract Ulva Lactuca and Sargassum sp. are rapidly expanding algae that can be used as a source of bioenergy. Due to its high moisture inorganic content, the direct use for energy purposes is deep. Therefore, thermochemical processing, such pyrolysis, required produce useful products, bio-oil. This study seeks undertake detailed investigation bio-oil production from provide information continued commercialization. The pyrolysis was investigated within temperature range 400-600 °C reaction time 10-50 min. highest proportion retrieved at 500 with yields between 18.5 30.2 wt%. As rose 600 °C, slightly increased, but prolonged did not significantly increase in yields. Gas chromatography-mass spectrometry (GC-MS) employed elucidate chemical composition found product. results showed phenolic compounds increased 9.64 16.73 area% an temperature. were obtained about 13.25% 16.73%, respectively. variations distribution total phenols may due species, sediment, surrounding water quality. achieved possible yield indicates potential renewable resins.
