A homogeneous Ru-pincer complex was immobilized by the supported liquid phase (SLP) technique and tested in continuous gas-phase steam reforming of methanol. Variations of catalyst composition (liquid phase, base and catalyst loading) as well as process parameters (temperature, flow rate) were carried out. High activity was obtained when ionic liquids were used for catalyst immobilization. However, better stability was obtained in the absence of ionic liquids using pure KOH.
