Highly efficient Ni–NiO/carbon nanotubes catalysts for the selective transfer hydrogenation of 5-hydroxymethylfurfural to 2,5-bis(hydroxymethyl)furan

Abstract

As a promising derivative to achieve efficient utilization of biomass, the preparation of 2,5-bis(hydroxymethyl)furan (BHMF) is of great significance. A kind of carbon nanotubes (CNTs) supported metallic nickel and nickel...

Continuous flow hydrogenolysis of 5-hydroxymethylfurfural into 2,5-dimethylfuran over alumina-supported nickel–iron alloy catalysts

“…[1][2][3][4][5][6][7] Therefore, the catalytic conversion under a hydrogen atmosphere of 5-HMF via hydrogenation and hydrogenolysis processes can produce various types of valuable products, such as 2,5-bis(hydroxymethyl)furan (2,5-BHMF), 2,5-dimethylfuran (2,5-DMF), 2,5-dimethyltetrahydrofuran (2,5-DMTHF), and hexanediols (HeDs). [8][9][10][11] Among the mentioned products, the catalyst development and production process of 2,5-DMF have been widely explored in the literature and it has gained recognition as the next generation of biofuels, owing to its high octane number and energy density, in addition to its insolubility in water compared with bioethanol. 1,[12][13][14] The catalytic conversion of 5-HMF into the high selectivity 2,5-DMF product involves controlling the extent of hydrogenation and hydrogenolysis with the inhibition of the furan ring hydrogenation and other side reactions.…”
