Background 2,5-Furandicarboxylic acid is a renewable building block for the production of polyfurandicarboxylates, which are biodegradable polyesters expected to substitute their classical counterparts derived from fossil resources. It may be produced from bio-based 5-hydroxymethylfurfural or 5-methoxymethylfurfural, both obtained by the acidic dehydration of biomass-derived fructose. 5-Methoxy...

The effect of infrared radiation (IR) on the physicochemical characteristics, pectin methylesterase activity (PME), hydroxymethylfurfural (HMF) content, microbiological activity, color, and sensory aspects black lime juice was studied. IR compared to conventional thermal heating (CTH) in batch extraction pasteurizer, designed allow both heating. resulted a reduction pH Brix values mild increase...

• Experimental and in-silico study on HDO of biobased 5-hydroxymethylfurfural. Deoxygenation at higher temperatures relative to reduction the aldehyde. Despite reducibility improvements, La promotion slowed reaction rates activity. Nb facilitated deoxygenation humin formation. Directly comparable kinetic parameters TOF for carbon-supported Ni catalysts. Catalytic hydrodeoxygenation hydroxymethy...
