    Furfural (FUR) was produced from xylose using a biphasic batch reaction system. Water-immiscible organic solvents such as isophorone, 2-methyltetrahydrofuran (2-MTHF) and cyclopentyl methyl ether (CPME) were used to promptly ...
  • Fast furfural formation from xylose using solid acid catalysts assisted by a microwave reactor 

    Gómez Millán, Gerardo; El Assal, Zouhair; Nieminen, Kaarlo; Hellsten, Sanna; Llorca Piqué, Jordi; Sixta, Herbert (2018-12-15)
    Article
    Open Access
    The production of furfural (FUR) from xylose was carried out using sulfated zirconia (SZ) on cordierite, alumina on cordierite and commercially-available polymeric solid catalysts (Amberlyst DT and Nafion NR40) to provide ...
  • Furfural production in a biphasic system using a carbonaceous solid acid catalyst 

    Gómez Millán, Gerardo; Phiri, Josphat; Mäkelä, Mikko; Maloney, Thad; Balu Balu, Alina-Mariana; Pineda Pineda, Antonio; Llorca Piqué, Jordi; Sixta, Herbert (2019-09-05)
    Article

    The formation of furfural from xylose was investigated under heterogeneously catalyzed conditions with Starbon®450-SO3H as a catalyst in a biphasic system. Experiments were performed based on a statistical experimental ...
  • Furfural stability in various conditions 

    Oreiro Muzas, Olaya (Universitat Politècnica de Catalunya / Universty of Oulu, 2011)
    Master thesis (pre-Bologna period)
    Restricted access - author's decision
    The topic of this thesis is the study of the furfural stability to determine the influence of some conditions in furfural degradation. The aim of the study is to decrease furfural degradation and thus improve furfural yield ...
  • Microwave-assisted furfural production using hectorites and fluorohectorites as catalysts 

    Sánchez, Vladimir; Dafinov, Antonio; Salagre, Pilar; Llorca Piqué, Jordi; Cesteros, Yolanda (2019-09-01)
    Article
    Open Access
    It has previously been reported that the use of microwave heating, together with the presence of co-solvents, improves the efficiency of furfural production from biomass. Solid acid catalysts can be a good alternative to ...
  • Potential of nanofiltration and reverse osmosis processes for the recovery of high-concentrated furfural streams 

    Mohamad, Nurabiyiah; Reig i Amat, Mònica; Vecino Bello, Xanel; Yong, Kelly; Cortina Pallás, José Luís (2019-01-01)
    Article
    Open Access
    Furfural is an interesting compound that can be produced from renewable and sustainable resources and is used in platform chemicals for the synthesis of biofuels and other chemicals. However, a recovery step is required ...
