NIKKEL/SILISIUMDIOKSYD-KATALYSATOR, DENS FREMSTILLING OG ANVENDELSE. |
摘要 |
<p>The invention provides a nickel/silica catalyst optionally also containing cations of a lower Group II metal (X), which catalyst satisfies the following combination of features: 1) a molar ratio of SiO2 / Ni = 0.15 - 0.35 2) a molar ratio of X / Ni = 0 - 0.15 3) an active nickel surface area above 120m<2>/g 4) a BET surface area of which at least 40% is found with pores with a radius above 2.5 nm. Preferably the catalyst has an atomic X/Ni ratio between 0.05 - 0.10 and a BET surface area of which at least 45% is found in pores having a pore radius of above 2.5 nm. The group II metal X is preferably magnesium or barium. y</p> |
