Abstract

A condensed liquid obtained after separation of gaseous components from the gas produced by the steam reforming reaction of methanol is brought into contact, in a gaseous phase, with catalyst (I) containing copper oxide (A), oxide of at least one type of metals selected from the group consisting of zinc, aluminium and chromium (B) and oxide of the group VIII metal in the periodic table (C), or catalyst (II) comprising the group VIII metal in the periodic table or compound thereof supported on carriers. The treatment of the condensed liquid yields water containing substantially no methanol, ethanol and high boiling point components. The treated condensed liquid causes no pollution problem when disposed as effluent and may be reused for the steam reforming reaction of methanol.
