| titleOfInvention | A kind of preparation method of high activity residuum hydrogenating and metal-eliminating catalyst |
| abstract | The invention discloses a kind of preparation method of high activity residuum hydrogenating and metal-eliminating catalyst, including following content：（1）The polyalcohol and/or the monose aqueous solution of at least two various concentrations are prepared, is sprayed on the alumina support according to the order of concentration from high to low so that the concentration of polyalcohol and/or monose forms ecto-entad in gradient distribution from low to high on carrier；（2）Alumina support after dipping is subjected to hydro-thermal charing process, drying process in sealing container；（3）With the aqueous solution impregnation steps containing active component and urea（2）Obtained alumina support, the material after dipping, which is transferred in closed container, carries out hydro-thermal process, dries, then anaerobic high-temperature process, obtains Hydrodemetalation catalyst.Carbon content distribution gradient in catalyst prepared by the inventive method, the easy complete cure of active component, active metal component are evenly distributed in carrier surface, significantly improve the metal removal activity of catalyst. |
