Abstract
Disclosed are a catalyst including copper (Cu) particles having specific properties as an active metal dispersed and supported on an alumina support, a method of preparing the same, and a method of hydrogenating furan-based compounds such as 5-(hydroxymethyl)furfural (HMF) derived from biomass with a high selective conversion and high efficiency using the catalyst.
Claims19
A method for preparing bis-2,5-hydroxymethylfuran (BHMF) from 5-hydroxymethylfurfural (HMF) comprising:
- feeding a feedstock comprising 5-hydroxymethylfurfural (HMF);
- and
- hydrogenating the feedstock in a liquid reaction medium using a catalyst containing a mesoporous alumina-containing support and particles of copper as an active metal on the mesoporous alumina-containing support to convert the 5-hydroxymethylfurfural (HMF) in the feedstock to bis-2,5-hydroxymethylfuran (BHMF),
- wherein the catalyst has (i) a copper particle size of 15 nm or less, (ii) a copper content of 15 to 40% by weight based on the element, and (iii) a copper specific surface area (SCu) of 6 to 35 m2/g, and (iv) a pore size of 2 to 6 nm.
