Embodiment 1

[0011] moisture

[0012] The processing method of generator tar is characterized in that its manufacturing steps are as follows:

[0013] 1) Put the grade I tar whose properties are shown in Table 1 into a high-position bubbling dehydration kettle with a lifting hopper, heat the material to 92°C, and mix the amount of air blown in with the tar 200m 3 The / t ratio is blown into the air for dehydration, and the water content of the dehydrated grade I tar is less than 0.2%, and it flows into the coker by its own gravity.

[0014] 2) The dehydrated grade I tar is heated and carbonized in the coker to 650°C, and the coke produced is discharged into the cooling box, cooled to below 100°C and discharged from the device; the tar vapor distilled from the top of the coker flows into the tar after being condensed and cooled storage tank.

[0015] 3) The tar is pumped into the alkali washing tank and mixed with a 15% sodium hydroxide aqueous solution, the reaction temperature...

Embodiment 2

[0020] The processing method of generator tar is characterized in that its manufacturing steps are as follows:

[0021] 1) Put the grade II tar whose properties are shown in Table 1 into a high-position bubbling dehydration kettle with a lifting hopper, heat the material to 98°C, and mix the amount of air blown in with the tar 200m 3 The / t ratio is blown into the air for dehydration, and the water content of the dehydrated grade II tar is less than 0.2%, and it flows into the coker by its own gravity.

[0022] 2) The dehydrated grade II tar is heated and carbonized in the coker to 500°C, and the coke produced is discharged into the cooling box, cooled to below 100°C and discharged from the device; the tar vapor distilled from the top of the coker flows into the tar after being condensed and cooled storage tank.

[0023] 3) The tar is pumped into the alkali washing tank and mixed with a 15% sodium hydroxide aqueous solution, the reaction temperature is 60°C, and the ratio of ...

Abstract

The invention relates to a method for handling producer gas tar, which is characterized in that: reducing the viscosity of I coke tar or II coke tar by heating, removing the moisture contained in I coke tar or II coke tar by air-blowing dehydrolyzing method; produing the coke and tar oil distillate by method of high temperature carbonization; adopting tar oil distillate to extract the mixing phenol; the significant effect of this invention is that it can produce modified components of coke, mixing phenol and fuel oil by low-temperature blowing, bubbling, de-watering, charring, alkali cleaning and acid cleaning the I coke tar or II coke tar which is hard to transport or deal with and can be easily contaminated. The invention not only solves the problems of environmental contamination brought by producer gas tar, but also improves the self-value of the producer gas tar and makes the precious hydroxybenzene resources put to effective utility.

Description

technical field [0001] The invention relates to the technical field of processing viscous plastic organic matter, in particular to a method for processing viscous plastic low-temperature coal tar produced by-product of gas produced by a gas generator. Background technique [0002] The production of gas by gas generator is the main production process for obtaining low calorific value gas in many countries in the world. During the production process, the raw coal gas produced by the gasifier escapes together with tar vapor, coal powder and coal ash in a high-temperature state. Spray with cold water to cool down the raw gas, and after separating part of the coal tar, coal powder and coal ash, the raw gas passes through the tar device to collect the remaining tar and part of the water. The coal tar, coal powder, and coal ash produced by cooling and washing raw gas with cold water spray form a viscous mixture and a large amount of water flows into the tar sedimentation tank, and...
