ARTEAGA V., JUAN C. et al. BIOFUELS PRODUCTION BY FAST PYROLYSIS OF PALM OIL WASTES (Elaeis guineensis Jacq.). Rev.Bio.Agro [online]. 2012, vol.10, n.2, pp.144-151. ISSN 1692-3561.

Biofuels were obtained by fast pyrolysis of palm oilwastes (Elaeis guineensis Jacq.) in a free fall reactor. Previously, palm oil wastes were dried and sieved and then were fed to the reactor. As pyrolysis products, char, non-condensable gas and bio-oil, a condensed liquid composed by alcohols, carboxylic acids, alkanes and aromatics, were obtained. The experiments were carried out at temperature range 500-700°C. The highest bio-oil yield, 23.3%, was obtained at 600°C. The gas compositional analysis showed CO2,720%, H0,703 % , CH1,289%, CO 22 4 2,472 % and N2 for the non-condensable gas produced at 600°C. The highest gas yield was obtained at 700°C but bio-oil yield was 14.9%. Results indicate that temperature has an important effect on the product yields and composition. A future step will be an economical analysis in order to evaluate the possibility of using non-condensable gas as energy source for pyrolysis reactor.
