Abstract

OSORIO, Alexander; GOMEZ, Elkin; OCAMPO, David  and  RIOS, Luis A.. Solvothermal Liquefaction of Acacia Wood ( Acacia mangium ). Inf. tecnol. [online]. 2019, vol.30, n.2, pp.211-222. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000200211.

Solvothermal liquefaction of Acacia mangium is presented. First, process variables, such as temperature, reaction time, and solvent-biomass ratio were optimized through 3k factorial experimental design. Results showed that at 270°C and solvent (water)-biomass ratio of 20- and 60-min reaction time, the highest biooil yield (40,2%) and highest HHV value (29,63 MJ/kg) were obtained. When energy yield, equipment dimension and energy consumption were taken into account, the best experimental conditions are 330°C for the solvent temperature, solvent (water)-biomass ratio of 15 and 0 min reaction time, with biooil yield 36% and heat power of 31,7MJ/Kg. Higher biooil yields (47,8%) resulted using acetone as solvent with almost the same heat power. Hydrogen atmosphere has a positive effect in the liquefaction only with acetone as solvent.
