Selective Furfural Hydrogenation to Furfuryl Alcohol Using Cu-Based Catalysts Supported on Clay Minerals

Clay as support for copper catalysts for the hydrogenation of furfural and phenolics

“…Figure shows the reduction profiles of copper oxides over the clay support treated by a variety of processes. The reducibility of copper oxide depended on the interaction with the support . There was only one peak in the reduction curve, indicating that only one type of CuO existed in the precursor and that the CuO was directly reduced to copper in the reduction process, which also was evidenced by the symmetry of the reduction peak.…”

The broad reduction peak indicated the reduction of CuO particles with a wide size distribution.…”

“…20,21 Active metals include noble metals, such as platinum (Pt), [22][23][24] palladium (Pd) 23,25,26 or ruthenium (Ru) 23 , are used in catalysts, but these noble metal-based catalysts are expensive, limiting their industrial application. Catalysts using transition metals, such as nickel (Ni), 27,28 cobalt (Co) 29 or copper (Cu), [30][31][32][33] also have good activity for furfural hydrogenation, but are relatively inexpensive. Among them Cu-based catalysts show good activity for hydrogenation of the aldehyde group in furfural but low activity for hydrogenation of the furan ring in furfural, which has been widely applied in the hydrogenation of furfural to furfuryl alcohol.…”

Alternative Recovery and Valorization of Metals from Exhausted Catalytic Converters in a New Smart Polymetallic Catalyst

“…Furfuryl alcohol ( 8 ), for instance, has important applications in the production of resins, fibres or as a solvent;, moreover, the transformation of furfural ( 7 ) into the corresponding furfuryl alcohol ( 8 ) is one of the methods used to avoid the reactions of condensation and polymerization to which furfural is subjected; this entails considerable difficulties in its conservation and storage . Copper chromite is used in the furfural industrial hydrogenation but, in order to avoid the high toxicity of chromium species, many other catalysts have been developed . So, considering the interest for the furfural molecule and its derivatives, we decided to test the activity and selectivity of Met x ‐EPS in the hydrogenation of furfural ( 7 ) (Scheme , Table ).…”

At room temperature in water: efficient hydrogenation of furfural to furfuryl alcohol with a Pt/SiC–C catalyst

“…To overcome this, chromium-free catalysts and noble metal promoted Cu-based catalysts have been developed. [11][12][13][14][15][16][17][18] For instance, Fulajtarova et al prepared a Pd-Cu/MgO catalyst for hydrogenation of FAL and a high FOL selectivity of 99% was obtained at 40 C. 13 A Cu/MgO catalyst also behaved well in the hydroconversion of FAL to FOL in vapor phase under the optimal conditions. 14,15 Besides, noble-metal catalysts also aroused intensive interests in this eld.…”
