Investigação dos métodos de separação, uso e aplicação da Lignina proveniente da biomassa lignocelulósica

This study investigated the main methods of separation of components of lignocellulosic biomass, with an emphasis on obtaining lignin and its application. The work was developed based on the concept of Biorefinery proposing full use of renewable raw materials and / or the use of lignocellulosic agricultural residues by biochemical or biotechnological conversion in obtaining high value added products with minimal environmental impact. From this premise, a literature review was performed in refereed journal articles and theses in order to gather enough material for critical analysis of usual and alternative methods in the literature. When researching methods that add value to lignin, it was found that with the technology found today, the cost required to have a degree of competitiveness is still too high, preventing much of the process. However, the isolated lignin can be used as raw material in the production of numerous types of biocomposites and polymers and other products such as phenols, benzene, dispersants, vanillin, emulsifying agents, antioxidants, pesticides, fertilizers, charcoal, concrete additives, among others. As an industrial production level is necessary, because the consumption of biomass will only grow over the years, it is necessary that new methods or technologies to be created in order to facilitate the extensive use of lignocellulosic biomass
