Embodiment Construction

[0023] use Figure 1-Figure 3 The method for increasing the diesel oil refining rate according to one embodiment of the present invention will be described below.

[0024] Such as Figure 1-Figure 3 Shown, a kind of diesel oil refining efficiency optimization method described in the present invention, this method comprises the steps:

[0025] S1: Use the heater to preheat the raw diesel to make it reach the reaction temperature, so that the diesel can have a faster reaction speed immediately after entering the liquid phase hydrogenation reactor, thereby shortening the speed of diesel refining;

[0026] S2: After heating in S1, inject the raw diesel oil that has reached the reaction temperature into the liquid phase hydrogenation reactor for hydrogenation treatment, so that the diesel oil can be hydrocracked rapidly, and the speed of diesel oil refining can be effectively improved;

[0027] S3: After the raw material diesel in S2 enters the liquid-phase hydrogenation reactor,...

Abstract

The invention belongs to the technical field of diesel oil refining, and in particular, relates to an optimization method of diesel oil refining efficiency. The method comprises the following steps: raw material diesel oil is subjected to heating treatment with a preheater to reach a reaction temperature; the raw material diesel oil reaching the reaction temperature is injected into a liquid-phasehydrogenation reactor and is subjected to hydrogenation treatment; and an elastic air bag is arranged between a first connecting rod and a second connecting rod of the liquid-phase hydrogenation reactor, a one-way gas intake valve and a one-way gas outlet valve are arranged, the one-way gas intake valve is connected with an external hydrogen tank, and the one-way gas outlet valve makes contact with a reactant directly; a hemispherical catalyst particle layer is laid on each of the upper surface and the lower surface of a piston plate of the liquid-phase hydrogenation reactor. The method is suitable for refinement of large quantities of diesel oil, and the diesel oil refining efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of diesel oil refining, in particular to a method for optimizing the efficiency of diesel oil refining. Background technique [0002] Diesel refining refers to the process of converting heavy diesel into light diesel through hydrocracking. High-speed diesel engines fueled by light diesel oil have high thermal efficiency and low specific fuel consumption, so they are widely used in heavy-duty and some medium-duty trucks, as well as a small number of light-duty cars and cars. Railway diesel locomotives, construction machinery and agricultural machinery also use light diesel as fuel. Light diesel oil should have good ignitability and low-temperature fluidity, as well as proper evaporation, viscosity and stability. These advantages of light diesel oil also make light diesel oil occupy an important position in social production, but the current production efficiency of light diesel oil is low, the energy consum...
