Special Issue Information

Dear Colleagues,

The catalytic conversion of renewable biomass platform molecules is a rapidly evolving field of research that has the potential to revolutionize the way we produce fuels and chemicals. However, this conversion has molecular diversity in processing and products, and precise conversion to specific chemicals has important scientific value and strategic significance for biomass valorization. In this context, catalytic conversion techniques have garnered significant interest as an efficient and sustainable means of converting biomass platform molecules into valuable chemicals and fuels.

Therefore, this Special Issue of Catalysts focuses on the catalytic conversion of biomass platform molecules (levulinic acid, glycerol, furfural,5-hydroxymethylfurfural, etc.). The Guest Editors welcome submissions of original research and review articles authored by researchers from all disciplines investigating topics relevant to catalytic conversion of renewable biomass platform molecules, including, but not limited to, the following:

  • Selective conversion of biomass platform molecules;
  • Catalytic synthesis of biofuels;
  • Furan derivatives production and application;
  • Catalytic production of bio-based alcohols, acids or amines;
  • Hydrodeoxygenation reaction for biomass conversion.

The non-oxidative dehydrogenation of ethanol into acetaldehyde is one of the efficient solutions for biomass upgrading. In this work, a series of copper catalysts supported on MgO with different Cu loadings ranging from 2.5% to 20% were prepared by an impregnation method. The as-synthesized Cu/MgO catalysts were characterized by N2 adsorption, XRD, TEM, CO2-TPD, XPS and TPR. These catalysts were found to be effective for ethanol dehydrogenation into acetaldehyde. As the Cu loading was increased, the ethanol conversion first increased and then leveled off. At a WHSV of 1.5 h−1 and 250 °C, the 20%Cu/MgO catalyst gave an initial conversion of 81.5%, with 97.7% selectivity toward acetaldehyde. Compared to 20%Cu/SiO2, the 20%Cu/MgO catalyst displayed an equivalent initial acetaldehyde yield, higher acetaldehyde selectivity and longer stability. Full article

Carveol is a rare fine chemical with specific biological activities and functions in nature. The artificial synthesis of carveol from plentiful and cheap turpentine is expected to further improve development of pharmaceutical and industrial applications. A new green catalytic system for the preparation of high-value carveol from α-epoxypinane is presented. A novel ammonium salt solid acid (AC-COIMI-NH4PW) was obtained from phosphotungstic acid bonded with imidazole basic site on nitrogen-doped activated carbon which, after ammonia fumigation, presented an excellent catalytic performance for the selective rearrangement of α-epoxypinane to carveol in DMF as solvent under mild reaction conditions. At 90 °C for 2 h, the conversion of α-epoxypinane could reach 98.9% and the selectivity of carveol was 50.6%. The acidic catalytic sites exhibited superior durability and the catalytic performance can be restored by supplementing the lost catalyst. Based on the investigation of catalytic processes, a parallel catalytic mechanism for the main product was proposed from the rearrangement of α-epoxypinane on AC-COIMI-NH4PW. Full article
