A novel catalytic membrane has been synthesised, characterised and evaluated for the selective hydrogenation of furfural to furfuryl alcohol. Unlike conventional methods, involving high pressure and high H2:feed ratios, this work proposes an innovative Ruthenium based Catalytic Membrane Reactor (CMR) to overcome mass transfer limitations, resulting in low H2 requirements, high catalytic activity and high selectivity towards furfuryl alcohol. A UV-curable hydrophilic anionic monomer acrylic acid was used as coating material onto a commercial PES membrane and subsequently Ru nanoparticles have been added. The hydrogenation of furfural has been carried out in a customised catalytic membrane reactor under mild conditions: 70 ºC and 7 bar, exhibiting high catalytic activity towards furfuryl alcohol (selectivity >99%) with turnover frequency (TOF) as high as 48,000 h-1, 2 orders of magnitude higher than those obtained so far.
