Let’s discuss coal-based diesel together~

I don’t know much about the theory behind them, only some practical knowledge. Later, when oil prices were high and diesel was in short supply, I tried to find alternatives. Coal contains coal tar, which has components similar to those in refined oil. After processing this refined oil, there are no more unpleasant odors, and its color is nice; it also doesn’t change color. However, it produces a lot of smoke, and I’m currently working on solving this problem. Do anyone have any good suggestions? Let’s talk about it together~~ This post was last edited by Zhenzhen Youci on 2009-3-10 at 10:48. Note: $ # $ $
I’m going to eat now. We can keep in touch here, or you can add me on QQ at 89109699 and by phone at 13933852551
In addition to simple distillation and hydrocracking, technologies for producing gasoline and diesel from coal tar include catalytic cracking and etherification, all of which are being studied in China. As demonstrated in the research conducted by the Institute of Thermal Physics, Chinese Academy of Sciences, coal-based wax oil obtained through the dehydration and deasphalting of medium- and low-temperature coal tar is used as the raw material. After desulfurization and denitration, catalytic cracking is carried out; the light components separated via distillation following cracking are then subjected to methoxylation, followed by blending to produce diesel.
I don’t really understand the theory behind it, but this is what I do: I buy special cleaning oils, which are also a type of coal. The current price is 2200 per ton. I add other substances to it and use steam to remove the unpleasant odor, as its smell is very bad. I also work on adjusting its color so that it doesn’t change color. Considering the cost of coal and electricity, the total cost comes to 3200; the price of diesel is 4100. But since my product doesn’t have the proper documentation, I can only sell it at 3700 to 3500
It’s hard to imagine what oil washing without hydrogenation is. Hua Er Bu Zai is indeed an individual operator who produces low-quality oil.
Low-quality oil? Maybe so; my oil isn’t legitimate, and even if it were legitimate, it would still be low-quality: lol :lol The cleaning oil I’ve created no longer has an unpleasant smell, as almost all the impurities have been removed from it. Its color is also great – as most people know, the color of cleaning oil usually changes to black after a few days, but mine remains unchanged for over a month. Its flash point is between 50 and 70, which is higher than that of standard diesel fuel. Another issue with cleaning oil is its corrosive nature; however, by adding anti-corrosive agents, it is no longer corrosive. I can use my product directly in vehicles, but for safety reasons, I currently mix my oil with 20% of high-quality oil. . . . There are two problems bothering me at the moment: 1) The smoke level is high, and no matter what methods I try, I can’t get it under control; 2) The density is quite high, around 1.3, and it seems difficult to reduce it to 0.84. Does anyone have any good suggestions?
If the smoke is smaller and the density is lower, the business prospects should be good. . . . :) :)
If you reduce the density to below 0.74, you will have successfully turned the washing oil into gasoline – keep up the good work! !
I’m switching to diesel; I’m afraid of the dangers associated with gasoline, haha `:)
It’s dangerous everywhere! Don’t be careless!
The problems related to density and smoke have been resolved~~Thank you all for your support~~`:victory: :victory:
The main component of washing oil is methylnaphthalene; the benzene rings cannot be saturated without hydrogenation, and carbon makes up a high proportion of it, which is quite different from the components of diesel.
I really appreciate you, bro; let’s keep in touch more often.
