Lignin is the second most abundant natural renewable biopolymer after cellulose on the earth. It is commonly generated as a by-product from the paper and ethanol industry. The complexity and richness of its functional groups make lignin attractive for converting into a variety of high-value products such as syngas, carbon fiber, phenolic resin, various oxidized products, and multifunctional hydro-carbons. This work intends to provide a comprehensive overview of structures and different types of lignin, as well as the recent progress in its preparation techniques. Besides, the extensive range of applications and opportunities of lignin were also discussed in detail. |
