It should be pointed out that the tincture oil in ancient China was not pure oil, but a product extracted from oil, which burned more violently than oil. If simple oil was used, the combustion was not strong enough and the killing effect could not be achieved.
Of course, in terms of combustion intensity, gasoline is definitely the most powerful among oil. In later generations, there were special gasoline bombs. Even this gasoline bomb can deal with tanks during World War II.
In addition, it should be emphasized that distillation of gasoline by civil method is very dangerous. Why? The danger is that it is dangerous - while distilling gasoline, there will be a by-product - liquefied petroleum gas.
The volatile liquidity of liquefied petroleum gas is even more powerful than gasoline, and it explodes when it reaches a certain concentration in the air, which is extremely dangerous.
However, Marin thought of a solution - to place the heating area of ​​the tin lens in the house, and the pipe part that collects gasoline was drilled through the wall and placed outside the house. In this way, even if the by-product of refining gasoline liquefied petroleum gas, which escaped in the air, the outside of the house was so large that it quickly dissipated.
If the exhaust port is placed in the house, it will be dead. Because the space inside the house is small, the liquefied petroleum gas has reached a certain concentration, and it will definitely explode when it encounters a heated open flame. Marin, a traveler, does not want to die, so he modified the tin glass and placed the exhaust port outside the house, allowing the liquefied petroleum gas to dissipate in the vast world. Of course, it also made people in the palace smell an unpleasant smell that day.
In fact, it is a very wasteful thing to let liquefied petroleum gas escape between the world. Because liquefied petroleum gas is a very excellent gas fuel and can even be used to make steel.
But the problem is that the yield of Marin's refining this time is very small, and it is not worth it to set up a pipeline system to collect liquefied petroleum gas. Therefore, Marin simply let the liquefied petroleum gas, which is by-product, escape between the world.
Smelling the faint smell of liquefied petroleum gas in the air, Marin said regretfully:
"Liquefied gas, it's a bottle of 100 or 100 yuan in the previous life, it's really a waste..."
However, he did not regret letting the liquefied gas escape. Why? Because collecting liquefied petroleum gas requires a long pipeline and some special equipment. If the pipeline is short and ignites immediately, the combustion of liquefied petroleum gas will go back to the gasoline collection area against the short pipeline and ignite the gasoline. Therefore, without wanting to be too troublesome, and the output is too small, Marin simply lets the liquefied petroleum gas escape outdoors. At the same time, the gasoline collection container is actually placed outdoors. In this way, the safety of people in the house can be fully guaranteed. Even if an explosion occurs, it will happen outdoors. You must know that Marin is standing in the house to direct the servants to operate. If an explosion is really done, he, the time traveler, will go to heaven, and the book can be finished hastily...
...
Although he is not a major in chemistry, Marin still found a picture of a petroleum fractionation tower from his memory of chemistry in middle school. This is a picture of a normal temperature fractionation tower. In this picture, it is clearly marked that liquefied petroleum gas is collected at the top of the tower, while the collection temperature of gasoline is 0~140 degrees; paraffin oil is 140~180 degrees; kerosene is 180~250 degrees; diesel is 250~350 degrees; and above 350 degrees, it belongs to the heavy oil range. In addition to asphalt, heavy oil can also be used as fuel. For example, the warship steam turbine boiler generally burns heavy oil; the lubricating oil is 380~500 degrees... As for those that are not vaporized above 500 degrees, it is very much a waste asphalt of oil. However, asphalt can also be paved...
Of course, this is just a schematic diagram of the simplest room temperature fractionation tower. In actual petroleum refining is very complicated. In addition to atmospheric fractionation, there is also low pressure fractionation. When we get light gasoline fractionation, it seems that the octane number is not high enough, and catalytic reforming is also required, such as hydrocracking. However, those are too complicated and Marin does not understand, he only knows the process of atmospheric fractionation.
Although the octane number of gasoline fractionated by the local method may not be high enough. However, Marin does not need too high octane. Because he made this primary earth gasoline in order to carry out fire attacks in war. If it is a fire attack, this earth gasoline is definitely enough...
...
Moreover, even the simplest atmospheric fractionation tower, Marin would never be able to do it. With his high school chemistry level, he would never be able to control the temperature of each outlet. A tower has seven or eight outlets, and the temperature of each outlet must be controlled within a certain range... This is too difficult... But if the temperature is not controlled properly, the fractionation tower will be in vain. Because if the temperature is deviated, it is easy to cause the mixing of different fractions - and then fractionation is required...
Moreover, in the low temperature zone, the limit of fractionation temperature is not obvious. For example, light oils within 170 degrees can be processed through catalytic reforming and other processing to become gasoline with high octane number. Therefore, the limit between gasoline and paraffin oil, paraffin oil and kerosene seems to be less obvious.
...
So Marin thought about it and refines the remaining oil again. However, this time, the refining temperature increased to 200 degrees. In order to control the temperature, Marin specially used a mercury thermometer to monitor the temperature to avoid excessive temperature.
Why should we prevent the temperature from being too high? Because Marin uses tin glass...
The melting point of tin is 231 degrees. If the temperature is too high, the container of tin lenses will be melted. How can you still refine it? If you want to refine oil in a higher temperature range, you must use a vessel made of copper or iron...
Then, at a high temperature of 200 degrees, Marin made another barrel of mixed oil containing heavy gasoline, paraffin oil and kerosene.
This oil is not as flammable as gasoline, but if it is mixed with gasoline, the firepower is also very strong. Anyway, Marin just wants to burn the wooden gates in Edinburgh, Scotland, and does not require gasoline of such high purity.
This chapter is not finished yet, please click on the next page to continue reading the exciting content below! So Marin took out half of this mixed oil and mixed it with the previous light gasoline. When mixing, Marin specially used the oil content of the upper half of this barrel of mixed oil. Because the lighter the oil, the stronger the combustion ability. Afterwards, he conducted a test and found that it was still very strong when burning, which was considered a very powerful fire attack oil.
As for the remaining oil mixed in the lower half of the barrel, it is estimated that most of the kerosene was found. So Marin asked the craftsman for help and made a simple kerosene lamp. The wick was a double-layer thin strip of wool cloth, and the oil lamp was also equipped with a knob for barbed wick made by the watchmaker. The lamp head was stuck on a glass bottle, and a simple glass cover was also made on it to prevent the kerosene lamp from being easily blown out by the wind.
In his previous life, Marin spent his time in the countryside when he was a child. At that time, the power supply in the countryside was very unstable and the power was always cut off intermittently. Therefore, every family in the countryside had kerosene lamps. Therefore, Marin was very familiar with kerosene lamps, and it was easy to get a kerosene lamp. After all, there were so many craftsmen under his command.
Light gasoline is too volatile, which can easily cause explosion and is not suitable for lamp oil. The barrel of mixed oil made by Marin only has some heavy gasoline that is not easy to volatile, and most of them float on the upper layer. The turbulent oil (mixed gasoline) is also mixed with turbulent oil (mixed gasoline). The remaining half of the barrel of oil is mostly composed of kerosene and paraffin oil, which is very suitable for lamp oil. Kerosene lamps are much stronger than the popular candles and torches now. At least, after adding a lampshade, you don’t worry about being blown out by the wind or being sneeze…
In addition, in order to further confuse the outside world's sight, Marin decided to add some materials to the barrel of mixed gasoline to cover others' eyes.
So Marin added red pigment to the mixed gasoline, making the mixed gasoline look bright red like blood. Can you imagine such red oil extracted from black oil?
In addition, Marin also added gelatin made of fish skin to it, making the mixed gasoline look very sticky. If an unknown person can guess the history, it would be a ghost.
Of course, the volatile smell of gasoline may make people notice. So, Marin added some seasonings to the smell to make the smell very unpleasant. In this way, it is difficult for ordinary people to smell the smell...
