| titleOfInvention | A kind of petroleum resin hydrogenation catalyst and its preparation method and application |
| abstract | The invention provides a petroleum resin hydrogenation catalyst and a preparation method and application thereof. The catalyst composition includes: zinc oxide-alumina modified carrier, active component Ni and additives; based on the total mass of the catalyst: the content of the zinc oxide-alumina modified carrier is 60wt% to 80wt%, the active component The content of Ni is 19.5wt% to 34.5wt%; the content of auxiliary agent is 0.5wt% to 5.5wt%. The catalyst is especially suitable for C9 petroleum resin hydrogenation process, can hydrogenate petroleum resin under mild reaction conditions, has the advantages of high catalytic activity, good stability, good anti-toxicity, long service life, etc. It can reduce the side reaction of hydrogenation, prevent the softening point of the product from being lowered too much, the unsaturated bond content in the prepared hydrogenated resin is obviously reduced, and the chromaticity is also greatly improved. |
