Biodiesel Technology Production of Diesel Oil by Coal Tar,Coal tar (including wash oil) is completely different from diesel. Or you want to say are all hydrocarbons, are almost the same. This is not the case, you look at the density between the two. Diesel is 0.85, coal tar is even 1 bar. This difference in density means that the hydrocarbon ratio is far from each other, which means that if you want to treat the coal tar as a diesel to sell, you have to hydrogenate, but with hundreds of thousands of the current size And equipment, you are certainly not through the hydrogenation of this step, then you come out of the oil, certainly can not be called diesel. After adjusting the density can go to 0.89, you are inside to add some small density of chemicals, diesel ingredients are not so reconciled to the.
Biodiesel Technology Production of Diesel Oil by Coal Tar,Diesel is the main component of paraffins, coal tar is the main component of polycyclic aromatic compounds, then straightforward point, that is, diesel inside the carbon and hydrogen, is linear (can have a chain) arrangement, and coal tar Inside the carbon and hydrogen are mainly in the form of rings, and are one or more rings connected together. You are in the process of dealing with the use of high temperature, the main is the high temperature cracking, part of the ring hydrocarbons are opened (chemical chemical called open loop) and part of the long chain hydrocarbons are also cut off (chemical chemical called cracking) Into a short chain of hydrocarbons. But you this process, because there is no hydrogen to join, will inevitably lead to poor quality of your oil. I wonder if you have found carbon deposition in the process? You even after the high temperature of the oil after you decolorize, the time put a little longer, the color will turn yellow, and this is what we said the stability of the poor oil, the main reason is that you have a large number of this product is not Saturated hydrocarbons, with air contact after being easily oxidized discoloration.
You refined processing, the purpose is to run your coal tar treated with diesel products compared to close to the product, and then when the diesel sold. You know do not know that you this product it just looks like diesel, but the main ingredients and performance, with the diesel is very different.Biodiesel Technology Production of Diesel Oil by Coal Tar.
If you really want to do diesel, then you have to hydrogenate, otherwise, it is not enough. But the hydrogenation, for your investment at this level, there is no possibility, even if your investment level to expand 100 times, basically still impossible.Biodiesel Technology Production of Diesel Oil by Coal Tar.
