Embodiment 1

[0032] The mixture of gas oil, catalytically cracked heavy oil and hydrogen enters the first hydrogenation reaction zone to contact with hydrogenation protection agent, hydrogenation deasphaltene agent, and hydrofining catalyst in order to react, based on the volume of catalyst in the first hydrogenation reaction zone The loading volume percentages of hydrogenation protecting agent, hydrodeasphaltene agent and hydrorefining catalyst are respectively 8 volume %, 15 volume % and 77 volume %; the reaction products are directly mixed with residual oil without separation and enter the In the second hydrogenation reaction zone, the weight percentage of residual oil entering the second hydrogenation reaction zone is 30% by weight based on the whole liquid-phase feed of the second hydrogenation reaction zone. The mixed raw material is sequentially contacted with the residual oil hydroprotecting agent, the residual oil hydrodemetallization catalyst and the residual oil hydrotreating cat...

Embodiment 2

[0036] The process flow of this embodiment is the same as that of Embodiment 1. The difference from Example 1 is that, based on the entire liquid-phase feed to the second hydrogenation reaction zone, the weight percentage of residual oil entering the second hydrogenation reaction zone is 15% by weight. Based on the catalyst volume in the first reaction zone, the loading volume percentages of hydrogenation protecting agent, hydrodeasphaltene agent and hydrorefining catalyst are 5 volume %, 12 volume % and 83 volume % respectively; Based on the volume, the loading volume percentages of the residual oil hydroprotecting agent, the residual oil hydrodemetallization catalyst and the residual oil hydrotreating catalyst are 5 vol%, 35 vol%, and 60 vol%, respectively. The catalytic cracking heavy oil obtained in this embodiment accounts for 20% by weight of the catalytic cracking feed,

Abstract

The invention discloses a method using gas oil and residual oil to process light fuel. The gas oil, catalytic cracking heavy oil and hydrogen are mixed to enter a first hydrogenation reaction area to react, the produced oil after the reaction and residual oil raw materials are mixed to react in a second hydrogenation reaction area, the obtained product after the reaction is separated to obtain a liquid phase product and a gas phase product, wherein the gas phase product is purified and pressurized to be fed back to the first hydrogenation reaction area for cycle use, the hydrogenation residual oil in the liquid phase product enters a catalytic cracking device to react, and the catalytic cracking heavy oil in a reaction product is circulated to the first hydrogenation reaction area. The method organically combines the heavy oil hydrotreatment and the catalytic cracking device, can translate inferior gas oil and residual oil into light fuel to the maximum extent, so the liquid yield is improved.

Description

technical field [0001] The invention belongs to a processing method of hydrocarbon oil, specifically a combination of a method for refining hydrocarbon oil in the presence of hydrogen and a method for cracking hydrocarbon oil in the absence of hydrogen. Background technique [0002] In recent years, with the rapid development of the national economy, oil consumption has shown a sharp increase, the contradiction between supply and demand is more prominent, the demand for heavy oil is decreasing, and the demand for light oil is increasing. Therefore, in order to make full and reasonable use of oil resources, the oil refining industry must provide Development in the direction of deep processing. In order to improve the depth of crude oil processing and increase the yield of light oil, lightening heavy oil has become one of the main tasks of the refining industry at present and in the future. [0003] Catalytic cracking is one of the most important crude oil secondary processin...
