Problems solved by technology

The annual output of tar in my country can reach 1.5 million tons, but more than 85% cannot be recycled
Although the environmental protection department has spent a lot of money to deal with these wastes, it still cannot completely eliminate its pollution.
Among them, the sulfide and nitrogen compounds have poor biodegradability, and their hazards cannot be reduced in the slightest whether they are buried or incinerated.

Embodiment 1

[0016] A kind of technology that utilizes waste coal tar to produce environment-friendly heavy oil, it comprises the following steps:

[0017] a. Collect waste coal tar;

[0018] b. Weigh the coal tar, and add it into the fractionator with the stabilizing additive in a ratio of 98:1, add zeolite into the fractionator, the temperature inside the fractionator is 70°C, and the vacuum in the fractionator is controlled at 500Pa, so The base naphthalene is quickly separated in the form of steam; and then heated to 100°C to realize the separation of carbazole, carbon black oil, phenol oil and asphalt, and produce residual oil;

[0019] Among them, asphalt can be made into modified asphalt after adding various modifiers. The main component of carbon black oil is filtered anthracene oil with very low sulfur content. Hydrogenation of anthracene oil can be made into naphtha, gasoline, diesel oil, fuel oil And various light fuel oils; and the 70 ℃ fractionation of naphtha can produce lig...

Embodiment 2

[0025] A kind of technology that utilizes waste coal tar to produce environment-friendly heavy oil, its specific process steps are as follows:

[0026] a. Collect waste coal tar;

[0027] B, take coal tar, and join in the fractionator with stabilizing additive according to the ratio of 100:2, add zeolite in the fractionator, the temperature in the fractionator is 75 ℃, the vacuum degree in the fractionator is controlled at 3600Pa, makes A The base naphthalene is quickly separated in the form of steam; then heated to 115 ° C to realize the separation of carbazole, carbon black oil, phenol oil and asphalt, and produce residual oil;

[0028] Among them, asphalt can be made into modified asphalt after adding various modifiers. The main component of carbon black oil is filtered anthracene oil with very low sulfur content. Hydrogenation of anthracene oil can be made into naphtha, gasoline, diesel oil, fuel oil And various light fuel oils; and the 106°C fractionation of naphtha can ...

Embodiment 3

[0034] A kind of technology that utilizes waste coal tar to produce environment-friendly heavy oil, its specific process steps are as follows:

[0035] a. Collect waste coal tar;

[0036] B, take coal tar, and join in the fractionator with stabilizing additive according to the ratio of 102:3, add zeolite in the fractionator, the temperature in the fractionator is 80 ℃, the vacuum degree in the fractionator is controlled at 6666Pa, makes A The base naphthalene is quickly separated in the form of steam; then heated to 130°C to realize the separation of carbazole, carbon black oil, phenol oil and asphalt, and produce residual oil;

[0037] Among them, asphalt can be made into modified asphalt after adding various modifiers. The main component of carbon black oil is filtered anthracene oil with very low sulfur content. Hydrogenation of anthracene oil can be made into naphtha, gasoline, diesel oil, fuel oil And various light fuel oils; and the 145°C fractionation of naphtha can pr...

Abstract

The invention relates to a technology for producing environment-friendly heavy oil by using waste coal tar. The technology comprises the following steps: collecting the waste coal tar, adding the collected waste coal tar into a fractionator together with a stabilizing additive, carrying out fractionation, and mixing to obtain the environment-friendly heavy oil. The technology provided by the invention can be used for extracting components or raw materials, which can be directly used, by using the waste coal tar; furthermore, the final residual oil is mixed with carbon black oil, methyl naphthalene, fuel oil, coal tar and heavy oil additives, so that the environment-friendly heavy oil can be obtained; therefore, the waste coal tar can be changed into valuable from waste, the resources are saved, the raw material and production costs are lowered, and the environment is protected.

Description

technical field [0001] The invention relates to circular economy, and in particular provides a process for producing environment-friendly heavy oil by using waste coal tar. Background technique [0002] With the rapid development of coal chemical industry and petrochemical industry, the treatment of its by-product—coking product becomes more and more important. Tar contains not only many residual extractable fuels, but also some extremely important organic compounds. The annual output of tar in my country can reach 1.5 million tons, but more than 85% cannot be recycled. Although the environmental protection department has spent a lot of money to deal with these wastes, it still cannot completely eliminate its pollution. Among them, the sulfide and nitrogen compounds have poor biodegradability, and their hazards cannot be reduced at all whether they are buried or incinerated. The utilization of tar oil in foreign countries is much higher than that in China. Fuel and many o...
