Optimization of production of Lignocellulosic biomass bio-oil from oil palm trunk

Wood is biodegradable material. Using wood in long term requires preservation and protect. Wood preservation is able to lengthen its life at least three times than non-treated wood. Lignocelluloses biomass bio-oil is potential substrates as wood preservative. One of potential source as lignocelluloses biomass bio-oil is oil palm trunk. Production of lignocelluloses biomass bio-oil is influenced by numerous parameters such as, moisture content of wood, temperature and time of combustion. Response Surface Methodology (RSM) is a powerful and efficient mathematical approach widely applied in the optimization of process. The objectives of this research are to search an optimum condition of production of lignocelluloses biomass bio-oil of oil palm trunk. Optimization of production process of lignocelluloses biomass bio-oil is carried out by using RSM with three variable designs as introduced by Box-Behnken, including pyrolysis temperature at 350q degrees C, 400 degrees C and 450 degrees C; pyrolysis time of 60 minutes, 90 minutes and 120 minutes; and moisture content of 10%, 12.5% and 15% with 15 runs. The result shows that optimum production of lignocelluloses biomass bio-oil of oil palm trunk is obtained at pyrolysis temperature of 446.11 degrees C; pyrolysis time of 119.98 minutes and oil palm trunk moisture content of 9.26% and rendemen of production was 42.05%. This information will increase the optimization production of wood preservatives material from oil palm trunk in industrial scale. (C) 2015 Published by Elsevier B.V.
