Description
Technical field
The invention belongs to coal tar processing technology field, relate in particular to it is a kind of with cheap catalyst to high temperature coal tar
Oily efficient catalytic thermal cracking improves the added value of high temperature coal-tar with this.
Background technology
Principal by product of the high temperature coal-tar as coking accounts for the 3%-4% of Coking Coal Quality.According to incompletely statistics,
About 22,000,000 t of China's high temperature coal-tar aggregated capacity at present.High temperature coal-tar is mainly made of aromatic hydrocarbon, is formed more than 10,000 kinds,
Most coking of coal products are difficult to substitute, and content is less in coal tar.It can be seen that carrying out coal tar deep processing has
Very important meaning.But during current coal tar separation and process for refining, pitch accounts for more than 50% in coal tar,
Since pitch macromolecular is highly condensed aromatic compound, the complicated heavy organics of complicated and oxygen-containing, nitrogen, sulphur etc. are formed,
Cause its working ability poor.Therefore, in high temperature coal-tar pitch generally as replacement for heavy fuel, for glass, ceramics etc.
Thermal energy industry and as production carbon black raw material or for producing the carbon materials such as needle coke, carbon fiber.In order to improve high temperature coal tar
The added value of oil, economically viable mode are to carry out lighting processing to high temperature coal-tar to carry out fine chemicals to obtain
Enormous profits.
Hydrogenation of high temperature coal tar made fuel oil technology emerging in recent years opens the new way for improving its added value, the skill
Art is in high temperature, high pressure and H2Under the conditions of existing, hydrogenation reaction is carried out to high temperature coal-tar on catalyst bed, changes it
Molecular structure, and the hetero atoms such as N, S are removed, so as to obtain gasoline, diesel oil, kerosene lamp fuel oil.But due to high temperature coal-tar
Middle pitch accounts for more than 50%, causes the easy coking of catalyst, causes expensive catalyst service life very short, hydrogenation process hydrogen consumption
Greatly, cause the process industrialization difficulty big, less economical.
The content of the invention
To overcome the shortcomings of existing process technology, the invention aims to by selecting energy, efficiently thermal cracking high-temperature coal is burnt
High temperature coal-tar is efficiently converted into tar light oil, the warp of process is improved with this by the waste residue and waste product of oil as catalyst
Ji property.
To achieve the above object, the present invention adopts the following technical scheme that.
A kind of method for considering catalytic pyrolysis high temperature coal-tar to be worth doing with useless Fe of the present invention, specifically：Useless Fe bits are selected as urging
Agent is 0.1~10 in 500~800 DEG C of thermal cracking temperature, tar and catalyst quality ratio:1st, inert gas flow velocity for 50~
High temperature coal-tar is converted into tar light oil under 200ml/min.
Further, the thermal cracking temperature is 750 DEG C, tar and catalyst quality ratio are 7.5:1st, inert gas flow velocity
For 50ml/min.After carrying out thermal cracking to coal tar under this process condition, the upgrading tar being collected into is analyzed, as a result
It is：80% is tar light oil, and wherein fat compound is 23%, aromatic compounds 61%, phenolic compound 16%.
Compared with prior art, the present invention has following technique effect：
1st, it is the high value added utilization of high temperature coal-tar and the recycling of industrial residue waste product, provides a new think of
Road has economy and environment double benefit.
2nd, catalytic thermal cracking catalyst is cheap and easy to get, active height, and process economics are high.
3rd, catalytic pyrolysis technological operation is simple, is easily achieved, and has a good application prospect.
