Hydrogenation catalyst and use thereof for hydrogenating fischer-tropsch endproducts |
摘要 |
A hydrogenation catalyst particularly suitable for hydrogenating oxygenates in a hydrogenation unit of a Fischer-Tropsch plant is disclosed. A preferred embodiment comprises more than 5% and less than 20% nickel based on a wide pore alumina support. The catalyst successfully hydrogenates oxygenates which otherwise tend to poison a catalyst in a hydroconversion unit downstream. Moreover, the temperature at which the unwanted hydrogenolysis of long chain paraffins to methane occurs is higher for one catalyst disclosed herein than a comparable known catalyst. This allows the hydrogenation plant to operate at a higher temperature. |

1. A hydrogenation catalyst, the catalyst comprising a metallic active portion comprising nickel crystallites and a support comprising wide pore alumina, wherein the support does not catalyse an acid catalysed reaction and wherein over 90% of the pores within the support are sized between 100 Å-400 Å, wherein the catalyst comprises between 5 and 20% nickel and wherein the nickel crystallites are around 2.5 nm. |
