VILTRES-RODRIGUEZ, Roberto Alfonso  e  ALARCON-ZAYAS, Alejandro. Chemical characterization of bio-oil of the fast pyrolysis from biomass. Rev Cub Quim [online]. 2022, vol.34, n.1, pp. 131-158.  Epub 18-Fev-2022. ISSN 2224-5421.

Biomass from agricultural processes is an important resource for fast pyrolysis and its transformation into bio-oil and high added value products. Several Standards of American Society for Testing and Materials (ASTM) were used in order to the physical-chemical characterization of the biomass used and the bio-oil obtained. Representative samples of bio-oil 0,82; pyroligneous acid 0,18 t , non-condensable gases 0,25 t and carbon 0,42 t were obtained by the fast pyrolysis from a mixture of Elephant Capín (Pennisetum purpureum) with sugar cane (Saccharum officinarum) straw. Nighty three organic compounds belonging to carboxylic acids, phenols, derivatives of furan, ethers of lignin, a homologous series of n-alkanes from the bio-oil, and some aromatic nitrogenous compounds of high molar mass by gas chromatography with mass detector were identified. The caloric power of bio-oil is 20,20 MJ kg-1, facilitating its possible use as a biofuel.
