Dehydrogenation/dehydrocyclisation catalyst - of nickel/platinum metal-carrier type modified with indium/gallium oxide

摘要

Catalyst based on carrier(s) (e.g. Al2O3, opt. treated with HF or hydrolysed in flame, SiO2, MgO, ZrO2, Al silicate or aluminate spinel of group II metal) and 0.01-5 wt. % metal (oxide) (e.g. Ni, Pt, Ru, Pd, IR, Rh, Os) also contains 0.1-10 wt. % (w.r.t. carrier) activity modifier, e.g. In or Ga oxide. This is used in dehydrogenation and dehydrocyclisation of org. cods. contg. CH-CH group(s), esp. paraffins. Modifier imparts improved activity and active life.
