Biodiesel Production Line suppliers New Technology of Continuous Extraction of Diesel from Coal Tar,First, the coal tar can be refined diesel raw materials
1, coal tar can be refined
Coal tar is a liquid product of coal obtained during dry distillation and gasification. Depending on the dry distillation temperature and the method, the following tarages are available:
A, low temperature dry distillation tar, referred to as low temperature coal tar (450-650 ¡æ temperature is a byproduct of coking conditions);
B, low temperature and medium temperature furnace tar, referred to as low temperature mixed oil (600-900 ¡æ temperature conditions are coking by-products);
C, medium temperature vertical furnace tar, referred to as the temperature of coal tar (600-900 ¡æ temperature conditions are coke by-product);
D, high temperature tar, referred to as high temperature coal tar (belonging to 1000 ¡æ temperature conditions, coke by-product);
The flash point of coal tar is generally 96-105 ¡æ, the ignition point is 580-630 ¡æ; combustion calorific value is 35700-39000kj / kg.
Regardless of the kind of tar are irritating odor, was dark brown viscous. The best coal tar can be used for the extraction of diesel oil is the freezing point at 21 ¡æ, the proportion of 0.95 or so low-temperature coal tar, which moisture content of less than 2%, about 4% dry gas, containing tar-like diesel fuel composition in the 75-80 % Or so, and the other by-product heavy oil about 10%, the total yield of about 90%. Medium temperature coal tar can also be used as raw material for refining fuel oil. Choose such tar for processing diesel fuel oil raw materials have good economic benefits.
2, phenol oil can be refined. Phenol oil is part of the 170-210 ° C section
3, wash oil can be refined. The washing oil belongs to the component of the temperature range of 230-300 ¡æ in coal tar;
4, anthracene oil can be refined. Anthracene oil is part of the temperature range of 300-360 ° C.
All of the above raw materials can be used to extract fuel oil.
Second, refining diesel fuel oil main technical indicators
Diesel and fuel oil extracted with coal tar is beige (or orange), clear and translucent, high calorific value, can be widely used in industrial, civil fuel field, can be part of the alternative diesel to do power use.Biodiesel Production Line suppliers New Technology of Continuous Extraction of Diesel from Coal Tarl.
Third, the production of major equipment
Continuous into the oil and sludge slag reactor, secondary cracking reactor, heat exchanger, decolorization tank, stirrer, adsorption tank, flame arrester, oil pump, oil and water separator.
Fourth, the process of refining the line
Raw material oil pretreatment — continuous feeding — continuous vaporization (plus liquid catalyst) —- catalytic fractionation (by the fixed bed deep catalytic cracking) — cold suspect – oil separation – impurity (add De- leaching agent) – refined (additive) – refined oil
Fifth, technical characteristics
First, the production of high efficiency. The technical design clever, originality, the entire production process for continuous,
Second, the two-phase catalytic high oil quality. In this technology, a variety of depolymerizing agents and catalytic cracking agents can be used to carry out the deep cracking reaction of the raw material oil from the liquid phase to the gas phase. Under the action of the molecular sieve, the molecular weight carbon structure of the oil is close to the diesel oil, Ideal alternative fuel oil, can be equivalent to 0 #, – 10 # and other diesel.
Third, the operation simplifies the more environmentally friendly. As the feed and slag are fully automatic operation, greatly reduce the strength, especially in the fully sealed state of production, safe and environmentally friendly.
Fourth, reasonable and safe waste gas recovery device, significant savings in fuel.
