Catalytic Transformation of Biomass Derivatives to Value‐Added Chemicals and Fuels in Continuous Flow Microreactors

Biomass as a renewable and abundantly available carbon source is a promising alternative to fossil resources for the production of chemicals and fuels. The development of biobased chemistry, along with catalyst design, has received much research attention over recent years. However, dedicated reactor concepts for the conversion of biomass and its derivatives are a relatively new research field. Continuous flow microreactors are a promising tool for process intensification, especially for reactions in multiphase systems. In this work, the potential of microreactors for the catalytic conversion of biomass derivatives to value-added chemicals and fuels is critically reviewed. Emphases are laid on the biphasic synthesis of furans from sugars, oxidation and hydrogenation of biomass derivatives. Microreactor processing has been shown capable of improving the efficiency of many biobased reactions, due to the transport intensification and a fine control over the process. Microreactors are expected to contribute in accelerating the technological development of biomass conversion and have a promising potential for industrial application in this area.

“…[3] High selectivity to furfuryl alcohol (FA) has been demonstrated for numerous catalysts, [8][9][10][11][12][13][14][15][16][17] as the product of the first step in the hydrogenation pathway (Scheme 1b). Supports often include Lewis acids, such as g-Al 2 O 3 , [14,21,22] TiO 2 , [12,16,23] ZrO 2 , [8] CeO 2 , [14] SiO 2 [9,10] and Al-SBA-15, [24] basic metal oxides (MgO and ZnO) [11,14] and base metal carbonates (CaCO 3 ), [10] which assist in polarizing the furfural carbonyl bond and which can actively take part in one of the reaction pathways. [12,18] The production of MF is attractive, as it has a very low boiling point which enables efficient separation.…”

“…Only few studies reported high selectivity to 2-methylfuran (MF). [10,13,18,24,25] Molecular hydrogen (H 2 ) is mostly used as the reductant for catalytic furfural hydrogenation. MF has shown superior performance as an additive in gasoline fuels compared to other furfural hydrogenation products.…”

[8][9][10][11][12][13][14][15][21][22][23][24][25] The reduction by catalytic hydrogen transfer in various alcohols (ROH), however, is reported only in few cases.

Furfural takes an important position in hemicelluloses biorefinery platforms. It can be converted into a wide range of chemicals. One important valorization route is the catalytic hydrogenation. Whereas molecular hydrogen is mostly used in industrial hydrogenation processes, recent studies also showed that alcohols can be used as reductants from which hydrides can be transferred catalytically to furfural. This process is often assisted by the formation of significant amounts of side products, in despite of high yields to the hydrogenolysis product 2-methylfuran. The present work explores the catalytic behavior in batch and continuous flow of mono-and bimetallic nickel catalysts supported on activated carbon for the catalytic transfer hydrogenation of furfural in isopropanol.

Switching Selectivity in the Hydrogen Transfer Reduction of Furfural

et al. 2018

View full text Add to dashboard Cite

Supported Cu catalysts and bare inorganic oxides have been tested in the reduction of furfural to furfuryl alcohol under hydrogen transfer reaction conditions by using butanol as a donor. Bare oxides like zirconia and alumina were found to be more active than the corresponding supported catalysts and in particular high surface Zirconia gave a quantitative transformation of the aldehyde into alcohol in 2,5 h at 140 °C according to a pure Meerwein‐Ponndorf‐Verley mechanism. Competitive dehydrogenation of the alcohol formed on the surface of Cu catalysts strongly reduces their activity although selectivity to alcohols on zirconia and alumina supported catalysts keeps very high. On the other hand catalysts with a well‐defined Lewis acid character such as highly dispersed Zirconia on Silica allowed to obtain up to 64% yield in 2‐butyl‐furfuryl‐ether under the same conditions.
