Embodiment 1

[0018] Embodiment 1, as figure 1 As shown, the catalytic conversion reaction device for producing clean fuel oil from petroleum hydrocarbon raw materials is composed of a raw oil riser reactor 1 and a gasoline riser reactor 2, which are arranged side by side. The raw oil riser reactor 1 is composed of a pre-lift section 11 , a first reaction zone 12 , a second reaction zone 13 , and an oil and gas extraction zone 14 . The diameter of the second reaction zone 13 is 2.5 times that of the first reaction zone 12 . Gasoline gas-solid separator 16 is installed in feedstock oil riser reactor 1, the upper and lower parts of gas-solid separator 16 are respectively connected with gasoline riser pipe 15 and catalyst depressant pipe 17, the outlet of gasoline riser reactor 2 is connected with feedstock oil riser pipe The gasoline gas-solid separator 16 in the reactor 1 is connected, and the gasoline riser 15 extends out of the raw oil riser reactor 1 . The gasoline gas-solid separator 16...

Embodiment 2

[0021]Embodiment 2. In this embodiment, the diameter of the second reaction zone 13 of the raw oil riser reactor 1 is the same as that of the first reaction zone 12 . Others are the same as embodiment 1.

[0022] Depending on the purpose of the reaction, the controlled reaction conditions are different.

[0023] When the main purpose is to produce standard gasoline and diesel:

[0024] The outlet temperature of the first reaction zone 12 of the raw oil riser reactor 1 is controlled at 500-530°C, and the outlet temperature of the second reaction zone 13 is controlled at 485-520°C. Gasoline riser reactor 2 outlet reaction temperature is controlled at 420-490°C

[0025] When the main purpose is to produce liquefied gas:

[0026] The outlet temperature of the first reaction zone 12 of the raw oil riser reactor 1 is controlled at 530-600°C, and the outlet temperature of the second reaction zone 13 is controlled at 520-580°C. The outlet temperature of gasoline riser reactor 2 is...

Abstract

The invention relates the catalytic conversion method and apparatus used to product cleaning fuel oil with petroleum hydrocarbon material. The apparatus comprises raw oil lift leg reactor, which is installed gas-solid separator, and petrol lift leg reactor. The upper exit of the gas-solid separator is connected with petrol lift leg reactor and the lower exit is connected with catalyst depressant prescription pipe. The bottom of the petrol lift leg reactor is installed catalyst cooling and heat transfer pipe. The oil gas from petrol lift leg reactor is entered in raw oil lift leg reactor. The catalyst is added in the raw oil lift leg reactor to improve the catalyst / oil ratio and then the petrol gas is directly leaded out through lift leg. Petrol and heavy oil coordinate with each other and the olefin content of product is lower.

Description

technical field [0001] The invention belongs to the technical field of petroleum hydrocarbon catalytic conversion process devices, in particular to a catalytic conversion reaction method and device for producing clean fuel oil from petroleum hydrocarbon raw materials with high conversion rate and low olefin and low sulfur content gasoline. Background technique [0002] The catalytic cracking process has gone through 60 years of development and has made great achievements and technological progress. The development of society makes the requirements for this process continuously increase, especially in terms of environmental protection, which poses new challenges to the catalytic cracking process, that is, not only to achieve economic benefits but also to meet the requirements of environmental protection. The latest gasoline standards in developed countries require that olefins be below 20% (weight) and sulfur content be below 100PPM. 85% of China's gasoline comes from cataly...
