Embodiment 1

[0055]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%, make the pH value of water glass solution in the beaker be 2.0, add to above-mentioned Add 416.7g pseudo-boehmite in the solution (properties are as follows: pore volume 0.985mL / g, specific surface area is 313m 2 / g, the dry basis is 72wt%), after stirring evenly, add 83g of curing agent urea, add deionized water after the urea is completely dissolved, make the material in the beaker be a paste with certain fluidity, and use silicon dioxide and oxide The solids content based on aluminum was 33%.

[0056] Press the above paste material into the pre-prepared rigid body mold with spherical cavity and mandrel. After the paste material fills the entire cavity, insert the last short mandrel. When the short mandrel touches the first Fixed after the mandrel. Two vert...

Embodiment 2

[0060] The preparation process is as in Example 1, except that the mold is replaced, the diameter of the cavity and the mandrel is increased, and the prepared catalyst carrier B and catalyst B C The properties are shown in Table 1. Wherein, the outer diameter of the obtained catalyst carrier B is about 7.5 mm, and the diameter of the through holes is about 3.8 mm.

Embodiment 3

[0062] The preparation process is as in Example 1, except that 373g of nitric acid solution and 53g of nickel nitrate with a mass concentration of 62% will be slowly added to the beaker, and the solid content in terms of silicon dioxide and aluminum oxide is 35%, the prepared catalyst carrier C and Catalyst C C The properties are shown in Table 1. Wherein, the outer diameter of the obtained catalyst carrier C is about 5.5 mm, and the diameter of the through holes is about 2.5 mm.

Abstract

The invention discloses a processing method for acid-containing crude oil. The method comprises at least one upflow hydrogenation reactor, at least one kind of hydrogenation treatment catalyst is filled in the upflow type hydrogenation reactor; the hydrogenation treatment catalyst includes a carrier and an active component, wherein the carrier is A spherical shape with two through passages, the outer diameter of the ball is 5.0-8.0 mm, and the two passages pass through the center of the ball and are perpendicular to each other through holes, and the diameter of the through holes is 30% to 60% of the outer diameter of the ball. The method of the invention adopts a specific catalyst, has good hydrodeacidification performance and metal removal capacity, and has certain desulfurization and carbon residue and asphaltene conversion capacity, high hydrogenation activity, and long operation period of the device. Moreover, the method of the invention overcomes the problems of many types of catalysts in the current upflow reactor, cumbersome loading and unloading, back-mixing of different types of catalysts, and the like.

Description

technical field [0001] The invention relates to a processing method for acid-containing crude oil, in particular to a method for processing acid-containing crude oil by adopting an upflow hydrogenation process technology. Background technique [0002] Petroleum usually contains acid compounds, mainly in the form of naphthenic acid. The concentration or amount of acid in petroleum is expressed using the total acid number. The total acid number (TAN) refers to the number of milligrams of potassium hydroxide (KOH) required to neutralize all acidic components of 1 gram of crude oil or petroleum fractions, and the unit is mg KOH / g. [0003] In the process of petroleum refining, naphthenic acid in petroleum can directly react with iron, causing corrosion of refining equipment such as heating furnace tubes; it can also react with the protective film FeS on refining equipment, exposing new surfaces of metal equipment, subject to new corrosion. At present, ordinary refining equipm...
