Recent Advancement In Lignin Biorefinery: With Special Focus On Enzymatic Degradation And Valorization, Chong Li, Chao Chen, Xiaofen Wu, Chi-Wing Tsang, Jinhua Mou, Yun Liu, Carol Sze Ki Lin

Faculty of Science & Technology (THEi)

With the intensive development of lignocellulosic biorefineries to produce fuels and chemicals from biomass-derived carbohydrates, lignin was generated at a large quantity every year. Therefore, lignin has received increasing attention as an abundant aromatics resource in terms of research and development efforts for value-added chemicals production. In this review, studies about lignin degradation especially the crucial enzymes involved and the reaction mechanism were substantially discussed, which provided the molecular basis of lignin biodegradation. Then, the latest improvements in lignin valorization by biological methods were summarized and case studies about value-added compounds from lignin were introduced. Afterwards, challenges, opportunities and prospects …

A Review On High Catalytic Efficiency Of Solid Acid Catalysts For Lignin Valorization, Weixiang Guan, Chi-Wing Tsang, Carol Sze Ki Lin, Christophe Len, Haoquan Hu, Changhai Liang

Faculty of Science & Technology (THEi)

It is imminent to develop renewable resources to replace fossil-derived energies as fossil resources are on the brink of exhaustion. Lignin is one of the major components of lignocellulosic biomass, which is a natural amorphous three-dimensional polymer with abundant C-O bonds and aromatic structure. Hence, valorization of lignin into high value-added liquid fuels and chemicals is regarded as a promising strategy to mitigate fossil resource shortages. Solid acid catalysts are extensively studied due to environmentally friendly in terms of the ease of separation, recovery and reduced amount of wastes. Hence, this review focuses on summarizing the recent progress of catalytic …
