Embodiment Construction

[0015] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only drawn to illustrate the basic content of the present invention, and do not limit the scope of the present invention.

[0016] As shown in Figure 1, the hydrocracking reaction effluent 8 is heat-exchanged by the high-pressure heat exchanger 6 and enters the hot high-pressure separator 1 alone or together with the hydrocarbon oil 18 to be refined for gas-liquid separation. The hot high-pressure separator 1 is usually Operate under the conditions of pressure 5.0-20.0MPa and temperature 200-400°C. The gas phase 9 of the hot high-pressure separator is a mixture of hydrogen, small molecule hydrocarbons and light oil, which passes through the refined catalyst bed arranged on the top of the hot high-pressure separator from bottom to top, and the usual range of liquid hourly space velocity (LHSV) is 0.1 to 10 hr -1 ,...

Abstract

The invention discloses a manufacturing method of clean fuel, which is characterized by the following: adding catalyst bed on the heat low-pressure separator or hydrogenating refining reactor between heat low-pressure separator and cold low-pressure separator; cracking the hydrocarbon oil; manufacturing light-quality and clean fuel.

Description

technical field [0001] The invention belongs to the field of petroleum refining and relates to a method for producing clean fuel. Background technique [0002] With the strengthening of environmental awareness, the production and use of clean fuels has become a major development trend. Due to the use of hydrofining to produce clean fuel, which has the characteristics of high product yield, low pollution and no waste that is difficult to handle, hydrofining has become an important choice for refineries to improve product quality. Chinese patent CN1552812A discloses a deep desulfurization and dearomatization process for diesel oil. Hydrofining method is used to produce clean fuel. Due to the operation under hydrogen, high temperature and high pressure, the equipment investment and operation cost are high, which brings high cost to the refinery to produce clean fuel and reduces economic benefits. [0003] The hydrocracking unit is another important unit in the refinery. With ...
