Abstract
Chitin biomass, a rich renewable resource, is the second most abundant natural polysaccharide after cellulose. Conversion of chitin biomass to high value-added chemicals can play a significant role in alleviating the global energy crisis and environmental pollution. In this review, the recent achievements in converting chitin biomass to high-value chemicals, such as 5-hydroxymethylfurfural (HMF), under different conditions using chitin, chitosan, glucosamine, and N-acetylglucosamine as raw materials are summarized. Related research on pretreatment technology of chitin biomass is also discussed. New approaches for transformation of chitin biomass to HMF are also proposed. This review promotes the development of industrial technologies for degradation of chitin biomass and preparation of HMF. It also provides insight into a sustainable future in terms of renewable resources.
Highlights
Investigation of green renewable energy has gradually become a main research direction in recent years
Chitin biomass should be fully utilized like cellulose biomass biomass by converting to high value chemicals
HMF is way to improve the output of waste resources, and it is expected to lead to new directions for high-value an important way to improve the output of waste resources, and it is expected to lead to new utilization of chitin biomass
Summary
Investigation of green renewable energy has gradually become a main research direction in recent years. There is a growing interest in chitin biomass, and conversion of chitin biomass to high high value-added compounds has become new research hotspot. Chitin biomass should be fully utilized like cellulose biomass biomass by converting to high value chemicals. 2,5-furandialdehyde, 2,5-furandicarboxylic acid, levulinic acid (LA), and other high value-added chemicals fuels. Chitin biomass is anraw ideal raw material for preparation of HMF. HMF is way to improve the output of waste resources, and it is expected to lead to new directions for high-value an important way to improve the output of waste resources, and it is expected to lead to new utilization of chitin biomass. Directions for high-value utilization of chitin biomass. HMF and summarizes the methods and pathways during the conversion process under different the potential future research directions are proposed.
