Hydrogenation of Biomass-derived 5-hydroxymethylfurfural (HMF) over Pd Catalysts in Aqueous Medium

Supported Metal Catalysts for Total Hydrogenation of Furfural and 5-Hydroxymethylfurfural

The use of biomass-derived compounds as substitutes of pet roleum has received much a t tent ion1)~4). Because of the complex nature of biomass, the conversions of biomass to chemicals usually start with the production of small molecules called platform chemicals by thermal, chemical or biological processing5). Among these platform chemicals, furfural6) and 5hydroxymethylfurfural (HMF)7) are es...

Catalytic Conversion of Biomass-derived Carbohydrates into 5-Hydroxymethylfurfural using a Strong Solid Acid Catalyst in Aqueous γ-Valerolactone

Selective conversion of biomass-derived carbohydrates into 5-hydroxymethylfurfural (HMF) is of great significance for biomass conversion. In this study, a novel solid Brønsted acid was prepared simply by the copolymerization of paraformaldehyde and p-toluenesulfonic acid and then used to catalyze the conversion of various carbohydrates into HMF in γ-valerolactone-water (GVL/H2O) reaction medium...

Effect of Alkali Carbonate/Bicarbonate on Citral Hydrogenation over Pd/Carbon Molecular Sieves Catalysts in Aqueous Media

The efficient citral hydrogenation was achieved in aqueous media using Pd/CMS and alkali additives like K2CO3. The alkali concentrations, reaction temperature and the Pd metal content were optimized to enhance the citral hydrogenation under aqueous media. In the absence of alkali, citral hydrogenation was low and addition of alkali promoted to ~92% hydrogenation without reduction in the selecti...

Hydrogenation of Biomass Derived Oxygenates

A two-step approach for the catalytic conversion of glucose to 2,5-dimethylfuran in ionic liquids

Lignocellulosic biomass is an attractive resource for producing transportation fuels, and consequently novel approaches are being sought for transforming the lignin and cellulosic constituents of biomass to fuels or fuel additives. Glucose, the monomer of cellulose, is a good starting material for exploring such chemistries. We report here the results of an investigation aimed at identifying ca...
