[0108] The first embodiment of the present invention will be described in detail below.

[0109] [About Hydrocarbon Oil Hydrotreating Catalyst]

[0110] The catalyst for hydrotreating hydrocarbon oil according to the first embodiment of the present invention (hereinafter also referred to as the "catalyst of the present invention" in the item of the first embodiment) includes a γ-alumina carrier (hereinafter also referred to as an alumina carrier ) and active metal components, with specified properties. The properties of the γ-alumina carrier, the active metal component and the catalyst are described in detail below.

[0111]

[0112] The γ-alumina carrier constituting the above-mentioned hydrotreating catalyst is an oxide of aluminum except for impurity components, and its crystal state can be classified as γ-alumina, which is 100% γ-alumina. The so-called 100% γ-alumina means that it may contain impurities that are inevitably contained in the process of producing the alum...

Embodiment 1

[0250]

[0251] 1000 g of carrier A was sprayed and impregnated with impregnation solution a, then dried at 200° C., and fired in an electric furnace at 450° C. for 1 hour to obtain a hydrotreating catalyst (hereinafter referred to simply as “catalyst”, and the same applies to the following examples).

Embodiment 2～ Embodiment 16

[0252]

[0253] Catalysts of Examples 2 to 16 were prepared in the same manner as in Example 1 by combining the types of carriers (preparation examples) and impregnation solutions (preparation examples) prepared as described above in accordance with Table 1 described later.

[0254] Next, comparative examples will be described.

Abstract

To provide a hydrotreating catalyst for hydrocarbon oil, wherein the hydrotreating catalyst maintains high industrial productivity, has excellent desulfurization activity, and can regenerate a high performance catalyst. On a gamma-alumina carrier (a carrier composed of 100% gamma-alumina or an inorganic composite oxide carrier obtained by mixing gamma-alumina with a different metal element) are carried, for example, 15-28 parts by mass of molybdenum and / or tungsten in terms of oxides and 2-7 parts by mass of cobalt and / or nickel in terms of oxides with respect to 100 parts by mass of the catalyst, and the content of carbon derived from an organic acid is 2.0 parts by mass or less on an elemental basis. The catalyst has a specific surface area of 180-320 m2 / g, and has an average pore diameter of 50-110 as measured by a mercury penetration method. The ignition loss of the catalyst is 5.0% or less, and the adsorption amount of nitric oxide on the sulfide-treated catalyst is 8.0 ml / g or more.

Description

technical field [0001] The present invention relates to a hydrotreating catalyst for removing sulfur components in hydrocarbon oil in the presence of hydrogen, a method for producing the same, and a hydrotreating method. Background technique [0002] Hydroprocessing uses a catalyst to perform the reaction at high temperature and high pressure, but in order to improve the economical efficiency of the process by making the reaction conditions low temperature and low pressure, it is desirable that the activity of the catalyst be high. As a known technique regarding the reduction temperature of molybdenum, there are the following findings. [0003] R.L.Cordero disclosed that the reduction temperature of molybdenum under a hydrogen flow of a catalyst carrying molybdenum on alumina or silica varies greatly depending on the type and composition of the carrier. However, this cannot be said to be a practical opinion as a catalyst without the addition of nickel or cobalt as catalyst ...
