文摘

The marine brown macroalgae Laminaria japonica was converted into liquid oil through deoxy-liquefaction in a stainless steel microreactor. The liquid oil was mainly composed of aromatics, phenols, alkanes and alkenes, other oxygen containing compounds, and some nitrogen containing compounds. The HZSM-5 and metal modified Fe/HZSM-5 and Ni/HZSM-5 catalysts were introduced to investigate the yield, distribution, and properties of the liquid oil. For all catalysts, the aromatics and long-chain alkanes increased, while those phenols and nitrogen containing species decreased, contributing to a distinct decrease in oxygen content. A maximum oil yield of 15.32 卤 0.2% was obtained when the Ni/HZSM-5 catalyst was used. The aromatics and alkanes reached 9.15% and 22.96%, respectively, and the higher heating value was up to 44.58 MJ/kg. The results suggested that L. japonica has potential as biomass feedstock for fuel and chemicals and that the deoxy-liquefaction technique may be an effective way to convert macroalgae into high-quality liquid oil.
