HYDROGENATING CATALYST AND HYDROGENATION OF UNSATURATED HYDROCARBON

摘要

PURPOSE: To enhance the hydrogenation activity of unsatd. hydrocarbon by depositing 5 to 40 wt.% of active nickel having a surface area of 80 to 300 m<2> /g on an transition alumina carrier satisfying a specific X-ray diffraction diagram, thereby forming a catalyst. CONSTITUTION: The catalyst for hydrogenation is formed by depositing 5 to 40 wt.% of the active nickel having the surface area of 80 to 300 m<2> /g on the transition alumina carrier satisfying the X-ray diffraction diagram expressed by formula I. The BET-total surface area of the catalyst is adequately 50 to 200 m<2> /g and the transition alumina which does not contain pores of <=2.0 nm in radius is more adequate. The formed catalyst has a pore size distribution of substantially 3.5 to 30 nm and more adequately 4.0 to 20 nm. The hydrogenation treatment is executed by treating the unsatd. hydrocarbon in the presence of the catalyst described above.
