Abstract
Abstract Ground Laurocerasus officinalis R. wood was liquefied in an autoclave with or without alkali additives such as NaOH and Na 2 CO 3 at temperatures 523 ± 5 and 623 ± 5 K. The liquid products were extracted by a liquid–liquid extraction procedure using benzene, diethyl ether and 1-butanol as solvents. Maximum oil yields were obtained as 68.9% and 43.1% by using NaOH and Na 2 CO 3 , respectively at 3/5 alkali additive/sample ratios and at 623 ± 5 K. The proximate analysis data and the higher heating value (HHV) of the sample were also determined. The HHV of the sample as MJ/kg was calculated by the following equation: HHV = 33.5 ( C % ) + 142.3 ( H % ) - 15.4 ( O % ) - 14.5 ( N % ) The calorific value of the sample calculated by the above equation showed a mean difference of −4.47%. This result was in good agreement with the experimental result and the literature.
