| description | In this work, as a continuation of our previous study on fast hydrothermal liquefaction of macro-alga, the chemical compositions of bio-oil and water soluble products were further studied by Gas Chromatography Mass Spectrometry (GC-MS) and High Performance Liquid Chromatography (HPLC) techniques, respectively. Bio-oil produced at different hydrothermal liquefaction (HTL) conditions including holding time (5, 10, 15, 20 min), heating rate (585 and 321 °C/min), with and without KOH catalyst addition, were used in this study. The results show that water soluble products consist of mainly C5-C6 sugars and C4-C2 organic acids. The formations of these compounds were resulted from the de-composition of carbohydrates and alginate in the kelp biomass. Moreover, increasing heating rate and adding catalyst have similar effect on the compositions of the HTL bio-oil. |
