Downstream products of coal tar
Thread Content
In recent years, the processing of coal tar in our country has developed rapidly, but this progress is mainly reflected in terms of scale; there has not been much advancement in the deep processing of products； Progress has been made in the processing of asphalt, anthracene oil, and washing oil ； Progress in the development of phenol oil and other products is slow; let’s exchange ideas.
Shanxi Hongte has carried out the production of needle coke through asphalt processing, and the quality is quite good. Anthracene oil can generally be used to produce carbon black or crude anthracene, refined anthracene, and anthraquinone. The washed oil can be used to produce methylnaphthalene, industrial naphthene, biphenyl, fluorene, etc. Phenol can be refined to produce phenol, dimethylphenol, etc., while industrial naphthalene can be used to produce dinaphthol, refined naphthalene, phthalic anhydride, etc
Generally speaking, there are four main uses for coal tar: first, for export； II. Fuel ； III. Advanced processing of coal tar ； IV. Produce carbon black. In my opinion, from the perspective of improving the full utilization of coal tar and increasing its added value, both exporting it and using it as fuel are inappropriate. First, coal tar should be processed further, and then the anthracene oil and soft pitch components should be mixed together to serve as raw materials for producing carbon black. This is just my personal opinion.
