Abstract

The invention discloses a process flow for preparing diesel by using coal tar. The process flow is mainly characterized by comprising the following steps: arrangement of a raw-material tank (filling the coal tar into the raw-material tank), degumming treatment (injecting concentrated sulfuric acid into a degumming tank, and stirring to obtain degummed coal tar), vaporizing treatment (infiltrating the degummed coal tar into a high-temperature vaporizing tower, and vaporizing the degummed coal tar to obtain coal tar gas), hydrogenation in a catalytic tower (introducing the coal tar gas into the catalytic tower, and injecting hydrogen into the catalytic tower to carry out catalytic reaction under high temperature to obtain reacted gas), desulfurization phase in a desulfurization tower, condensation phase in a condensation tower, separation in an oil-water separator and the like). The process flow disclosed by the invention has the advantages of simpler technical scheme, low investment, fast effect, easy operation, high safety, good benefit and easy promotion.

Description

technical field [0001] The present invention relates to a field related to oil refining, especially a field closely related to the manufacture of diesel oil. More specifically, the present invention is a technical process for producing diesel oil from coal tar. The invention should be classified as C10 in the International Patent Classification. Background technique [0002] As we all know, as far as the world is concerned, the sum of petroleum energy and other combustible gas resources is much smaller than that of fossil energy; Natural gas etc. are significantly less. In addition, there is an existing process for producing diesel from coal tar, but the process is long and complicated, the production efficiency is not high enough, the investment is large, the safety is not high enough, the cost is high, and the operation is cumbersome. Contents of the invention [0003] The purpose of the present invention is to provide a short and relatively simple process flow, relat...
