Liquid Phase Pyrolysis of Giant Leucaena Wood to Bio-Oil over NiMo/Al2O3 Catalyst

Renewable fuels are major alternatives to fossil fuels. Biomass was considered as raw materials and renewable energy sources. Pyrolysis process is one of the efficient methods for converting biomass in bio-oil. This work investigates the pyrolysis of Giant Leucaena wood in liquid phase by various conditions: The experiments were conducted in an autoclave at following conditions; temperature of 325–400 °C, holding time of 0–60 min, biomass 250 gram, NiMo/Al2O3 catalyst weight (0–30 percent by weight) by using hexane as a solvent. Bio-oils were analyzed by gas chromatography–mass spectrometry to identify the structure and chemical compounds, also by CHN analyzer. The results showed that the liquid products were phenolic compounds, cyclic compounds and furans which were determined by gas chromatography.
