Embodiment Construction

[0011] In order to clearly illustrate the technical features of this solution, the specific implementation of the present invention will be further described below according to the accompanying drawings.

[0012] The invention is a device for producing diesel oil from coal tar, such as figure 1 As shown, it includes a separation reactor 1 with a feed inlet 2, a fractionation device 3 is provided at the top of the separation reactor 1, and a slagging outlet 8 is provided at the bottom, and the fractionation device 3 is connected with a belt outlet through a conduit 4. The synthetic reactor 7 of the oil port 10, and the agitator 6 is arranged in the synthetic reactor 7.

[0013] When producing diesel oil, the pretreated coal tar is sent into the separation reactor 1 through the feed port 2, and a liquid phase catalyst is added at the same time. The coal tar that enters the separation reactor 1 is gasified and separated. After gasification, the gas enters the fractionation devic...

Abstract

The invention relates to a device for producing diesel, in particular to a device for producing diesel from coal tar, which comprises a separation reaction kettle provided with a feed port, the top of the separation reaction kettle is provided with a fractionation device, the bottom of the separation reaction kettle is provided with a slag discharge hole, the fractionation device is connected with a synthesis reaction kettle provided with an oil outlet through a guide pipe, and the synthesis reaction kettle is internally provided with a stirrer. An impurity removing device in the synthesis reaction kettle can be used for further separating impurities to enable produced diesel to be more pure. As the synthesis reaction kettle is provided with the stirrer so that raw materials and a catalyst can be in full contact so as to save oil refining time. By means of the device provided by the invention, the coal tar can be effectively refined, the produced diesel can be prepared into a finished product of diesel as long as a decoloration-resistance additive is added. The device has a simple process, and can be used for continuous production so that the production efficiency is improved.

Description

Technical field: [0001] The invention relates to a diesel catalytic production device, in particular to a device for producing diesel from coal tar. Background technique: [0002] At present, the main raw material for refining and producing diesel oil is petroleum, which contains many components, the refining process and equipment are relatively complicated, and the input cost is high. However, my country is rich in coal resources, and there is a large amount of coal tar discharged from coking plants in various regions. Using these coal tars to refine diesel oil has huge economic benefits and important environmental protection significance. In the prior art, there are many methods for producing diesel oil from coal tar, but they cannot be effectively implemented because there is no complete set of refining equipment. The coal tar refining equipment on the market has shortcomings such as incomplete refining and synthesis, and incapable of continuous mass production, which gr...
