Problems solved by technology

The catalyst is suitable as a hydrodesulfurization catalyst, and it needs to be graded before the hydrodemetallization catalyst to prolong the service life of the catalyst. Therefore, it is not suitable for use in an upflow reactor alone

Embodiment 1

[0050] Take by weighing silicon oxide content and be that the water glass 1000g of 30wt% adds in the beaker, start stirring device, slowly add mass concentration in the beaker and be the nitric acid solution 376g of 62%, the pH value of the water glass solution in the beaker after stirring and dissolving is 2.0, then Add 62.5g of nickel nitrate, and after dissolving, add 468g of pseudoboehmite (properties are as follows: pore volume 0.985mL / g, specific surface area is 313m 2 / g, dry basis is 72wt%), after stirring evenly, add 83g of curing agent urea, after the urea is completely dissolved, add deionized water, so that the material in the beaker is a paste with a certain fluidity, and silicon dioxide and oxide The solids content is 33% based on aluminum.

[0051] The above paste mass is pressed into two identical hemispheres with spherical cavities. Wherein, a guide mold is placed in a hemisphere, and the guide mold is made of wood. The structure of the guide mold is three c...

Embodiment 2

[0056] The preparation process is as in Example 1, except that the curing agent urea is changed to add 97.2g of hexamethylenetetraammonium, and the prepared catalyst carrier B and catalyst B C The properties are shown in Table 1, and the catalyst evaluation results are shown in Table 2. Wherein, the outer diameter of the obtained catalyst carrier B is about 5.3 mm, and the diameter of the through holes is about 2.0 mm.

Embodiment 3

[0058] Preparation process is as embodiment 1, just increases the spherical cavity diameter of mold and the diameter of three cylinders in guide mold, the prepared catalyst C C The properties are shown in Table 1, and the catalyst evaluation results are shown in Table 2. The obtained catalyst carrier C had an outer diameter of about 7.6 mm and a through-hole diameter of about 3.8 mm.

Abstract

The invention discloses a catalyst carrier for residual oil hydrogenation treatment, a catalyst and a preparation method thereof. The carrier is spherical with three through passages, the outer diameter of the ball is 5.0-8.0mm, and the three passages are through holes passing through the center of the ball and perpendicular to each other. The diameter of the through holes is 30%-60% of the outer diameter of the ball. %. The catalyst prepared by loading the active metal component on the catalyst carrier of the present invention is especially suitable for the upflow residual oil hydrotreating process, and has the characteristics of high hydrogenation activity, long service life and the like.

Description

technical field [0001] The invention relates to a catalyst carrier, a catalyst and a preparation method thereof for residual oil hydrogenation treatment, in particular to a catalyst carrier, a catalyst and a preparation method thereof for upflow residual oil hydrogenation treatment. Background technique [0002] As crude oil becomes heavier and worse, more and more heavy oil and residual oil need to be processed. The processing of heavy oil and residual oil not only needs to be cracked into products with low boiling points, such as naphtha, middle distillate oil and vacuum gas oil, but also to increase their hydrogen-carbon ratio, which requires decarbonization or Hydrogenation method to achieve. Among them, the decarbonization process includes coking, solvent deasphalting, heavy oil catalytic cracking, etc.; the hydrogenation process includes hydrocracking, hydrofining, hydrotreating, etc. The hydrogenation process can not only hydrogenate and convert residual oil, improv...
