Abstract

Lignin is one of the most abundant compounds in the plant world, focused on being a replacement for oil in various applications. This research consists of the validation of the method «Determination of lignin in biomass» based on the NREL/TP 510-42618 methodology of the United States National Renewable Energy Laboratory, applied to pine biomass. By prior moisture quantification and testing of extractives in water and ethanol to eliminate interfering materials, lignin was quantified applying gravimetry and UV-Vis spectroscopy techniques at a wavelength of 240 cm, obtaining the soluble lignin content. and insoluble. From the results of the lignin content, the influence of the environmental conditions at each test level is evidenced, however, this influence did not cause a significant deviation when compared with the Horwitz equation. Thus, concluding that the chosen and established experimentation conditions of the range suggested by the NREL methodology allow a correct performance of the method applied to pine biomass, allowing it to be replicated in the future in different investigations in the country.
