Selective hydrodeoxygenation of 5-hydroxymethylfurfural to 2, 5-dimethylfuran over mesoporous silica supported copper catalysts

Selective catalytic hydrodeoxygenation (HDO) of 5-hydroxymethylfurfural (HMF) to prepare 2, 5-dimethylfuran (DMF) was studied as this product is a good biofuel. A sequence of copper dispersed on SBA-15 catalysts are designed and tested their activity for HMF hydrodeoxygenation reaction. The physico-...
