<P>PROBLEM TO BE SOLVED: To provide a method for the hydrogenation of olefins exhibiting excellent effect to reduce the pressure difference of the reactor by passing an olefin-containing liquid and a hydrogen-containing gas through a packed bed of a solid hydrogenation catalyst. <P>SOLUTION: Olefins are hydrogenated by passing an olefin-containing liquid and a hydrogen-containing gas through a packed bed of a solid hydrogenation catalyst, wherein the content of catalyst powder having a diameter of ≤1 mm in the catalyst bed is ≤5 wt.% and the flow rate of the liquid-gas mixture passing through the bed is ≥3 cm/sec in terms of superficial gas velocity. Examples of the solid hydrogenation catalyst are metal oxides containing one or more components selected from CuO, Cr<SB>2</SB>O<SB>3</SB>, ZnO, FeO<SB>3</SB>, Al<SB>2</SB>O<SB>3</SB>, La<SB>2</SB>O<SB>3</SB>, Sm<SB>2</SB>O<SB>3</SB>, CeO<SB>2</SB>, ZrO<SB>2</SB>, TiO<SB>2</SB>, SiO<SB>2</SB>, MnO<SB>2</SB>, Co<SB>2</SB>O<SB>3</SB>, NiO, BaO, CaO and MgO and noble metal catalysts containing Pd, Rh, Pt or Ru. <P>COPYRIGHT: (C)2008,JPO&INPIT |
