Embodiment 1

[0066] This embodiment is used to illustrate the method for producing gasoline from Fischer-Tropsch synthetic oil provided by the present invention.

[0067] After preheating, the Fischer-Tropsch synthetic oil enters the riser reactor 1 under the lifting action of the atomized water and contacts and reacts with the hot high-temperature regenerated catalyst A. The temperature of the catalyst A is 650℃. The water-to-oil ratio is 5%; the oil agent moves upward along the riser reactor under the lift of the atomized water; the reaction conditions of the riser reactor include: reaction temperature of 500℃, agent-oil weight ratio of 8, and mass space velocity 20h -1 After the reaction is complete, the oil is separated from the gas and solid by the cyclone separator in the settler 2; the aromatization reaction material enters the aromatization riser reactor 3 under the lifting action of the atomized water after being preheated and is combined with the aromatization The aromatization cata...

Embodiment 2

[0069] This embodiment is used to illustrate the method for producing gasoline from Fischer-Tropsch synthetic oil provided by the present invention.

[0070] Gasoline was produced according to the method of Example 1, except that catalyst B was used instead of catalyst A. The distribution of the obtained products is shown in Table 5.

Embodiment 3

[0074] This embodiment is used to illustrate the method for producing gasoline from Fischer-Tropsch synthetic oil provided by the present invention.

[0075] After being preheated, the Fischer-Tropsch synthetic oil enters the riser reactor 1 under the lifting action of the atomized water and contacts and reacts with the hot high-temperature regenerated catalyst A. The temperature of the catalyst A is 600℃. The water-to-oil ratio is 8%; the oil agent moves upward along the riser reactor under the lift of the atomized water; the reaction conditions of the riser reactor include: reaction temperature of 450°C, weight ratio of agent to oil of 5, and mass space velocity 10h -1 After the reaction is complete, the oil is separated from the gas and solid by the cyclone separator in the settler 2; the aromatization reaction material enters the aromatization riser reactor 3 under the lifting action of the atomized water after being preheated and is combined with the aromatization The aromat...

Abstract

The invention relates to the field of catalytic cracking of Fischer-Tropsch synthetic oil and concretely discloses a method for producing gasoline from Fischer-Tropsch synthetic oil. The method comprises that (1) Fischer-Tropsch synthetic oil undergoes a cracking reaction in the presence of a cracking catalyst in a first reactor to produce a first reactant flow, (2) an aromatizing raw material undergoes an aromatization reaction in the presence of an aromatization catalyst in a second reactor to produce a second reactant flow, and (3) the first reactant flow and the second reactant flow are poured into a settler and are separated, the separated catalyst to be regenerated is subjected to steam stripping, then at least one part of the catalyst enters a regenerator and is regenerated through charring, and at least one part of the regenerated catalyst is returned into the first reactor and then is recycled. The method can improve the octane number of gasoline and produce a high gasoline yield.

Description

Technical field [0001] The present invention relates to a method for converting Fischer-Tropsch synthetic oil in the absence of hydrogen, and in particular, to a method for producing gasoline from Fischer-Tropsch synthetic oil. Background technique [0002] With the implementation of the national policy of sustainable development of my country’s national economy, the air pollution caused by automobile exhaust has become a focus of attention. The most critical issue facing my country’s petroleum refining industry is to produce clean fuels that meet the country’s increasingly strict environmental standards. To meet the needs of the domestic transportation industry and the market. [0003] The declining reserves of conventional petroleum resources and the rapid increase in consumption have made the technology of producing synthetic oil by the Fischer-Tropsch synthesis method attract much attention. Fischer-Tropsch synthetic oil is significantly different from conventional petroleum fr...
