The production of chemicals via acid-catalysed dehydration of sugars is inevitably related to the formation of co-products. Noteworthy, a black and viscous polymeric co-product called humins can be formed in significant quantities. Humins are heterogeneous and polydisperse macromolecules, mainly constituted by furanic rings and aldehydes,...

Humins is a biomass-derived material, co-product of the acid-catalyzed conversion of cellulose and hemicellulose to platform chemicals. This work presents a thorough study concerning the crosslinking kinetics of humins by chemorheological analysis and model-free kinetics under isothermal and non-isothermal curing. Humins can auto-crosslink...

Conversion of lignocellulosic biomass often brings along the formation of several side products. Among these, the formation of a black and viscous co-product so-called humins is observed due to acidic treatment of polysaccharides. To improve the efficiency of this process from an economical and environmental prospective, new solutions for...

Industrial humins from biorefining process of sugars were used as reactive thermoset matrix for the preparation of humins-jute fibre composites. This material was investigated and benchmarked with jute composites prepared with polyfurfurylalcohol (PFA), a well-known biobased thermosetting resin The Dynamic Mechanical Analyses (DMA) showed glass...
