AI Technical Summary

Problems solved by technology

The process of preparing tetralin and its alkylated derivatives is expensive and thus the final product is quite expensive
The high price of tetralin hinders the application of this prior art method in the oil refining industry

Embodiment 1

[0050] A starting mixture was prepared by mixing 300 g of tar, 6 g of typical Baltic shale, and 9 g of a hydrocracked product with a boiling point of 300-400°C. The above components were mixed together in a heated mixer at 75°C for 1 hour. The mixture is then subjected to thermal cracking without homogenization.

[0051] The thermal cracking program is carried out at a pressure of 4MPa and a temperature of 425-430°C for 30 minutes. The resulting liquid product was filtered to remove solids. The liquid product is distilled into a fraction with a boiling point below 180°C (gasoline), a fraction with a boiling point of 180-360°C (diesel oil), a fraction with a boiling point of 360-520°C (gas oil), and a residue with a boiling point above 520°C. The process characteristics are listed in Table 1 below.

Embodiment 2

[0053] The raw materials and process characteristics are similar to Example 1, but the raw materials are homogenized for one stage at a temperature of 85-95°C. The process characteristics are listed in Table 1 below.

Embodiment 3

[0055] The raw materials and process characteristics are similar to Example 1, but the raw materials are homogenized in two stages: the temperature of the first stage is 85-95°C, and the temperature of the second stage is 95-105°C. The process characteristics are listed in Table 1 below.

Abstract

A method for producing distilled fuel that is used as raw material to produce fuel of engines includes mixing residual oil with peat and 1-5 wt.% hydrogenated cut fraction with boiling point at 300-400 degreees, putting the mixture in an actuating reactor to homogenizing in two stages at 85-105 degrees, then thermal cracking or hydrocracking, and extracting distilled fuels (gasoline, diesel oil or coarse diesel oil) from the products. This invention can be used in oil refining industry.

Description

field of invention [0001] The present invention relates to petroleum refining, and more particularly, the present invention relates to a method for producing fuel distillate from residual oil by hydrocracking or thermal cracking using a donor solvent method. [0002] The progress of petroleum processing technology has raised the problem of deeper processing of petroleum. The solution to this problem must be widely realized for residue oils containing high concentrations of heavy metals, especially vanadium and nickel, such as black oil, tar and heavy hydrocarbon oil ( Secondary treatment of soft asphalt). Background of the invention [0003] So far, one of the most hopeful methods to solve the above problems is to make residual oil and coal to carry out thermal cracking, wherein the consumption of coal is 5~30% of the quality of oil (US, A, 4544479,1985; RU, A , 2009166, 1994). [0004] The prior art method involves subjecting the mixture to mild therm...
