“…[76] FDCA has applications in the pharmaceutical industry and is a monomer for polyethylene furanoate (PEF), [67,68] a biobased alternative for polyethylene terephthalate (PET) used in the production of e. g., plastic drinking bottles. [84][85][86][87][88] Top value-added chemicals derived from (pyrolytic) lignin are mainly aromatic components (e. g., BTX), [89] phenol and a variety of lignin monomer molecules (e. g., propylphenol, eugenol, syringol, aryl ethers or alkylated methyl aryl ethers). [79] Furfural can be hydrogenated to furfuryl alcohol (monomer for furan resins), [80] 2-methylfuran (potential biofuel), [81] and/or 2-methyltetrahydrofuran (MeTHF), a non-toxic solvent.…”

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.

A route for directional conversion of bio‐oil into phenol by means of coupling the catalytic cracking of the bio‐oil with the hydroxylation of the bio‐oil‐based benzene‐rich aromatics is proposed. High selectivity for phenol in the resulting organic liquid was achieved, with an almost complete conversion of the bio‐oil. Co‐cracking of the bio‐oil with methanol over a Zn‐modified zeolite significantly enhanced the yields of aromatics and decreased the deactivation of the catalyst during the catalytic cracking of the bio‐oil. The phenol yield depended on the metal oxide catalysts, the temperature, and the reaction time during hydroxylation of the benzene‐rich aromatics. The reaction pathway of converting bio‐oil into phenol was elucidated based on the products identified and the characterization of the catalysts.

“…The use of renewable biomass for the synthesis of petrochemicals is crucial to reduce the dependency on limited reserves of fossil fuels [1][2][3][4]. Due to the structure and availability, lignin is considered as a promising resource of aromatic hydrocarbons which are industrially important feedstock for producing a wide variety of useful chemicals such as polymers, pharmaceuticals, agrochemicals and electronic chemicals [5].…”

“…Then, the reaction proceeds through (ii) dehydrogenation of 5 to 6, (iii) acid-catalyzed dehydration of 5 to 4, (iv) hydrogenation of 4 to 3, (v) dehydrogenation of 4 to 2 and (vi) hydrogenation of 2 to 3. Typical HDO reaction of phenols into aromatics proceeds via the direct hydrogenolysis of phenolic C−O bond, which generally requires high temperature over 300 °C [3].…”

Selective hydrodeoxygenation of lignin-related 4-propylphenol into n-propylbenzene in water by Pt-Re/ZrO2 catalysts

et al. 2014

View full text Add to dashboard Cite

Abstract:Bimetallic Pt-Re/ZrO 2 catalysts were developed for the selective hydrodeoxygenation of 4-propylphenol as a lignin model to n-propylbenzene in water. The addition of Re to Pt/ZrO 2 improved the catalyst stability and product selectivity. Reaction temperature greatly affected not only reaction efficiency but also product distribution. n-Propylbenzene was obtained in up to 73% yield with ca. 80% selectivity. After the reaction, the catalyst was deactivated possibly due to waterinduced wrapping of Pt nanoparticles in ZrO 2 . The reaction may involve the hydrogenation of 4-propylphenol to 4-propylcyclohexanol, followed by the dehydration to give 4-propylcyclohexene and the subsequent dehydrogenation to n-propylbenzene.
