Embodiment

[0036] In this example, the combined method of wax oil hydrotreating and catalytic cracking provided by the present invention is used to circulate the catalytically cracked heavy fraction including catalytically cracked diesel oil, catalytic heavy cycle oil and catalytic oil slurry to a hydrotreating unit for further processing. Table 2, Table 3, and Table 5 are process conditions, product distribution, and main product properties, respectively.

[0037] The comparison results show that the yield of FCC gasoline increases by 22.96 percentage points, the yield of coke decreases, and the yield of dry gas and liquefied gas increases after the mixed hydrotreating of FCC heavy distillate oil and fresh wax oil feedstock. This method can well satisfy enterprises wishing to increase gasoline production.

Abstract

The invention discloses a wax oil hydrogenated treatment and catalytic cracking combined method, which comprises the following steps of: performing hydrogenated reaction on hydrogenated treatment raw materials in the presence of hydrogen and hydrogenated treatment catalyst, performing gas-liquid separation on the hydrogenated reaction effluent, circulating the gas phase for the hydrogenated reaction, directly feeding the liquid phase into a catalytic cracking device without fractionation, and mixing dry gas and liquefied gas separated from the catalytic cracking reaction effluent, catalytic cracking heavy fraction formed by catalytically cracking gasoline and the hydrogenated treatment raw materials to perform hydrogenated reaction. Compared with the prior art, the method can produce maximum gasoline, meanwhile saves equipment investment, makes full use of reaction heat energy and reduces the production energy consumption.

Description

technical field [0001] The invention relates to a method for lightening wax oil, specifically a process for producing gasoline products by organically combining hydrogenation treatment and catalytic cracking and using wax oil as a raw material. Background technique [0002] At present, the demand for light and medium oil products, especially gasoline, in the domestic and foreign oil product markets will continue to rise, while the demand for heavy oil products will show a downward trend. At the same time, the properties of crude oil are deteriorating day by day on a global scale, and environmental regulations are becoming stricter. Therefore, how to realize the lightening of heavy oil at a more economical and reasonable price, and the refining technology that the obtained products can meet the increasingly stringent specifications of gasoline and diesel products has become one of the key technologies developed by domestic and foreign refining technology developers.
