Conversion of biomass into valuable chemicals is a highly sought process. 5-hydroxymethyl-2-furaldehyde (HMF) plays a key role in biorefinery, being employed for the sustainable production of fuels and chemicals. In particular, the highly active and selective hydrogenation of HMF to 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) has drawn much attention for their broad applications. In this research, the hydrogenation in aqueous solution of HMF to BHMF and BHMTHF in autoclave was studied with commercial Pt/C, Ru/C and Pd/C catalysts and the influence of many reaction parameters was optimized. Ru/C resulted the most promising system, allowing a high selective yield towards each of the two monomers, depending on the reaction conditions. Hydrogenation studies on biomass-derived HMF to BHMF and BHMTHF in the presence of Ru/C were also performed without isolation of the intermediate HMF, paving the way for the reaction directly from biomass.

Abstract
Conversion of biomass into valuable chemicals is a highly sought process. 5-hydroxymethyl-2-furaldehyde (HMF) plays a key role in biorefinery, being employed for the sustainable production of fuels and chemicals. In particular, the highly active and selective hydrogenation of HMF to 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) has drawn much attention for their broad applications. In this research, the hydrogenation in aqueous solution of HMF to BHMF and BHMTHF in autoclave was studied with commercial Pt/C, Ru/C and Pd/C catalysts and the influence of many reaction parameters was optimized. Ru/C resulted the most promising system, allowing a high selective yield towards each of the two monomers, depending on the reaction conditions. Hydrogenation studies on biomass-derived HMF to BHMF and BHMTHF in the presence of Ru/C were also performed without isolation of the intermediate HMF, paving the way for the reaction directly from biomass.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
