Single-step catalytic conversion of furfural to 2-pentanol over bimetallic Co–Cu catalysts

Abstract

Catalytic conversion of furfural to 2-pentanol over Co–Cu/Al2O3 catalysts.

Solid Acids for the Reaction of Bioderived Alcohols into Ethers for Fuel Applications

“…On the other hand, the production of bio-alcohols through fermentation processes, particularly ethanol from cellulosic biomass and ethanol/butanol mixture through ABE fermentation of starch and glucose, is growing continuously. Butanol and longer chain alcohols can also be obtained through Guerbet reactions of bio-ethanol [86], 2-pentanol [87], and furfurilic alcohol from furfural, in turn obtained from hemicellulose together with HMF. Some of these bioalcohols can be used as biofuels themselves, but upgrading them through the synthesis of ethers would greatly improve their performance.…”

Furfural hydrogenation to 2‐methylfuran over efficient sol‐gel copper‐cobalt/zirconia catalyst

“…[60] Also, 5.6% 2-MTHF and 4.7% pentanol were formed under 2 MPa pressure, indicating that hydrogenation of MF occurred and pentanol was obtained by ring-opening reaction. Seemala et al [61]…”

“…Nguyen-Huy et al [39] synthesized a series of mesoporous CuCo oxide catalysts from mesoporous silica, KIT-6 template, and their Cu 1 Co 5 catalyst resulted in approximately 70% of furfural conversion and 60% MF yield at 180 C after 9 hours under 2.0 MPa H 2 . However, Wang et al [30] also examined catalysts with highly dispersed CuCo-based mixed metal/metal oxide on porous carbon matrix for the hydrogenation of furfural, and their CuCo 0.4 /C catalyst showed a 98.7% furfural Seemala et al [61] Co-Cu-SBA-15 170 2 4 99 80 FA (S) Srivastava et al [29] CuCo-carbon 140 3 1 98.7 97.7 FA (S) Wang et al [30] Cu-Co/Al 2 O 3 220 4 5 100 87 MF (Y) Srivastava et al [60] Cu-Co/γ-Al 2 O 3 220 4 4 100 78 MF (S) Srivastava et al [65] Cu-Co/γ-Al 2 O 3 220 3 4 100 80 MF (Y) Gandarias et al [66] Co-Cu-SiO 2 200 1 bar -60 98 FA (S) Reddy et al [67] Cu 1 Co 5 180 2 9 70 60 MF (Y) Nguyen-Huy et al [39] Co-Cu/ZrO conversion and 97.7% FA selectivity in ethanol solvent at 413 K and 3 MPa hydrogen pressure. Different from the other studies, Gong et al [68] reported an almost 100% yield of 2-MF within 4 hours at 170 C reaction temperature under 3 MPa H 2 pressure in the presence of the activated carbon (AC) supported Cu-based catalyst.…”

Effect of Ni Metal Content on Emulsifying Properties of Ni/CNTox Catalysts for Catalytic Conversion of Furfural in Pickering Emulsions

“…[21,22] The relevance of FAL catalytic conversion comes from the large number of chemicals and biofuels that can be obtained from its transformation. [23][24][25][26][27] FAL can be converted to long-chain products by CÀ C coupling condensation reaction, [28,29] valuable fuel additives such as 2-methyltetrahydrofuran (2-MTHF) [30] and furfuryl ether (FFE), [31,32] and to value-added compounds such as furan by decarbonylation, [33] furfuryl alcohol by hydrogenation [34,35] and by hydrogenation/ ring rearrangement to cyclopentanone (CPO). [36][37][38][39][40] Particular focus has been put on the transformation of furfural to aliphatic cyclic molecules such as cyclopentanone and cyclopentanol because they are important intermediate in fine chemical industry with a broad range of application in the perfume, medicine, and agriculture field.…”

“…According to the US Department of Energy, furfural (FAL) has been selected as one of the top 30 building blocks obtained from biomass, [20] which can be converted directly or indirectly to more than 80 chemicals due to its high chemical reactivity [21,22] . The relevance of FAL catalytic conversion comes from the large number of chemicals and biofuels that can be obtained from its transformation [23–27] . FAL can be converted to long‐chain products by C−C coupling condensation reaction, [28,29] valuable fuel additives such as 2‐methyltetrahydrofuran (2‐MTHF) [30] and furfuryl ether (FFE), [31,32] and to value‐added compounds such as furan by decarbonylation, [33] furfuryl alcohol by hydrogenation [34,35] and by hydrogenation/ring rearrangement to cyclopentanone (CPO) [36–40] …”
