Abstract

A hydrogenation treatment catalyst and its application, the catalyst contains a carbon-containing heat-resistant inorganic oxide carrier and a hydrogenation active metal component loaded on the carrier, based on the carrier, the content of carbon in the carrier It is 0.3-5% by weight, and it is characterized in that, described carrier is mixed, shaped, dried and Activation, the activation includes: (1) in the presence of isolated air and / or inert gas, heat treatment of the dried molding, the heat treatment temperature is 400-800 ° C, and the time is 0.5-8 hours; (2) Under water vapor and / or carbon dioxide atmosphere, the product of step (1) is heat-treated, the heating temperature is 600-950°C, the time is 0.3-4 hours, and the flow rate of the water vapor and / or carbon dioxide is 50-500 standard Liter / kg·hour. The catalyst is suitable for hydrotreating hydrocarbon oil to produce clean oil.

Description

technical field [0001] The invention relates to a hydrotreating catalyst and its application. Background technique [0002] Increasing awareness of environmental protection and stricter environmental regulations force the oil refining industry to pay more attention to the development of clean fuel production technology. How to economically and reasonably produce ultra-low sulfur oil products has become one of the key issues that the oil refining industry needs to solve at present and in a certain period of time in the future. one. The development of new hydroprocessing catalysts with higher activity and selectivity is one of the most economical ways to produce clean oils. [0003] Hydrotreating catalysts are metal sulfides of Group VIB (such as Mo and W) and Group VIII (such as Co and Ni) supported on a carrier, and the carrier is generally γ-Al 2 o 3 . [0004] As one of the important components of the hydrogenation catalyst, the surface properties of the support have a...
