The highly-efficient conversion of 5-hydroxymethylfurfural (HMF) to 2,5-bis(ethoxymethyl)furan (BEMF) was achieved over the copper-loaded hierarchically structured ZSM-5 (Cu/HSZ) catalysts in the continuous fixed-bed reactor. The main reaction path for BEMF synthesis on the Cu/HSZ catalysts was confirmed as following: HMF was firstly hydrogenated to BHMF intermediates over metal sites and then the formed BHMF was etherified by acid sites. Benefiting from the ammonia evaporation (AE) method promoted the dispersion of copper and reduced the acidity, the Cu/HSZ-AE catalyst exhibited more excellent BEMF yield and stability than the catalyst prepared by conventional incipient-wetness impregnation (Cu/HSZ-IW). Indeed, the inactivation of Cu/HSZ-IW catalyst was mainly attributed to the deactivation of copper by carbon species deposition.

An efficient process for the catalytic transfer hydrogenation of biomass-derived 5-hydroxymethyl furfural (HMF) to 2,5-bishydroxymethyl furan (BHMF) is presented using ethanol as a hydrogen donor and solvent over low-cost ZrO(OH)2. A HMF conversion of 94.1% and a DHMF selectivity of 88.9% were achieved at 423 K in 2.5 h. The fresh, spent, and regenerated catalysts were characterized comprehensively, and the OH group of ZrO(OH)2 as sites for ligand exchange with ethanol was considered to be important for the activity.

We report a one-step process for the production of diesel fuel from biomass-derived 5-hydroxymethylfurfural (HMF). The reaction proceeds through the sequential transfer hydrogenation and etherification of HMF to 2,5-bis(alkoxymethyl)furan, a potential biodiesel additive, catalyzed by a Lewis acid zeolite, such as Sn-Beta or Zr-Beta. An alcohol is used as a hydrogen donor and as a reactant in etherification. This cascade reaction can selectively produce high yields of the biodiesel additive (>80 % yield) from HMF with the Sn-Beta catalyst and secondary alcohols, such as 2-propanol and 2-butanol. Diesel addiction: Biomass-derived 5-hydroxymethylfurfural (HMF) is converted to 2,5-bis(alkoxymethyl)furan, a potential biodiesel additive, through sequential transfer hydrogenation and etherification reactions catalyzed by a Lewis acid zeolite, such as Sn-Beta or Zr-Beta. Sn-Beta selectively produces high yields of the biodiesel additive (>80 % yield) with secondary alcohols, such as 2-propanol and 2-butanol, as hydrogen donors and as etherification agents. Copyright
