Embodiment 1

[0024] A kind of VGO is used as raw material oil A, and the properties of raw material oil are shown in Table 1. From Table 1, it can be seen that the sulfur content of raw material oil A is as high as 27000 μg / g. The raw material A enters the hydrogenation reactor together with the hydrogen, and successively contacts and reacts with the hydrogenation protection agent and the hydrogenation catalyst. The effluent after the reaction is cooled and separated, the hydrogen-rich gas is recycled, and the liquid product enters the fractionation system to be separated into naphtha Distillate, Diesel Distillate and Refined Gas Oil Distillate. Based on the overall catalyst volume, the loading volume percentages of the hydrogenation protecting agent and the hydrotreating catalyst are respectively 9% and 91%, wherein the hydrogenation protecting agent includes the hydrogenation protecting agent I and the hydrogenation protecting agent II, both of which are loaded The volume ratio is 1:1. ...

Embodiment 2

[0026] A mixed oil of DAO, CGO and VGO (mass ratio 36:5:59) is used as raw material B, and its properties are shown in Table 1. It can be seen from Table 1 that the metal content of raw material B is 3.0 μg / g. The raw material oil A enters the hydrogenation reactor together with the hydrogen, and reacts with the hydrogenation protection agent, the hydrodemetallization catalyst and the hydrogenation treatment catalyst in sequence. The effluent after the reaction is cooled and separated, the hydrogen-rich gas is recycled, and the liquid product enters the The fractionation system separates into naphtha fraction, diesel fraction and refined gas oil fraction. Based on the overall catalyst volume, wherein the loading volume percentages of hydroprotecting agent, hydrodemetallization catalyst and hydrotreating catalyst are respectively 12%, 23% and 65%; wherein the hydroprotecting agent comprises hydroprotecting agent 1 and As for the hydrogenation protecting agent II, the filling ...

Abstract

The invention relates to a hydrogenation method for high- quality catalytic cracking material. It comprises: carrying out hydrogenation and modifying reaction for mixture of raw oil and hydrogen gas in hydrogenation preservative, any hydrogenation demetalation catalyst and hydrogenation treating catalyst in turn; and the filling volumetic percentage of mentioned preservative and catalyst are 2- 15%, 0- 30% and 55-95%, cooling reactant and separating and getting a large amount of refined gas oil fraction, part of low-sulphur diesel fraction and little amount of benzine naphtha fraction, and the refined gas oil fraction is the catalytic cracking material. The invention can prolong the operation cycle for device under high percentage of desulfurization, the activity of employed catalyst is high, and the rational packing method ensures better catalyst activity, and reduces production cost. The invention is characterized by simple process, low operation pressure, low device investment and operation cost.

Description

technical field [0001] The invention belongs to a method for refining hydrocarbon oil in the presence of hydrogen, more specifically, a hydrogenation method for producing high-quality catalytic cracking raw materials. Background technique [0002] Experts predict that in the next ten years, the demand for light and medium oil products in the domestic and foreign oil product markets will continue to rise, while the demand for heavy oil products such as fuel oil will show a downward trend. In addition, due to the increasing pressure of environmental protection, countries have generally raised the quality standard requirements of petroleum products, especially gasoline and diesel products for vehicles. Under the above-mentioned market trend, the refining technology that can not only realize the lightening of heavy oil at a more economical and reasonable price, but also make the obtained products meet the increasingly stringent specifications of gasoline and diesel products has ...
