It should be pointed out that the ancient Chinese kerosene is not pure oil, but a product extracted from oil, which burns more fiercely than oil. If you use pure oil, the burning is not strong enough to achieve enough killing effect.

Of course, when it comes to the intensity of combustion, gasoline is definitely the most powerful. In later generations, there are special gasoline bombs. Even this gasoline bomb can deal with the tanks of World War II.

In addition, it should be particularly emphasized that indigenous distillation of gasoline is very dangerous. why? The danger is that while distilling gasoline, there will be a by-product liquefied petroleum gas.

Liquefied petroleum gas is more volatile than gasoline, and it explodes when exposed to an open flame after reaching a certain concentration in the air, which is extremely dangerous.

However, Marin thought of a way to put the heating zone of tin tin inside the house, and the pipe part for collecting gasoline was cut through the wall and placed outside the house. In this way, even if liquefied petroleum gas, a by-product of refining gasoline, escapes in the air, it can be so large outside that it quickly dissipates.

If the exhaust 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 is heated by an open flame. Marin, the traverser, didn't want to die, so he modified the tin and put the exhaust vent outside the house, allowing the LPG to dissipate in the vast world. Of course, it also made people in the palace that day smell a bad smell.

As a matter of fact, it is very wasteful to let liquefied petroleum gas escape between the world and the earth. Because, LPG is a very good gas fuel. Even, it can be used to make steel.

But the problem is that the output of Marin's refining this time is very small. It is not worthwhile to get a pipeline system to collect liquefied petroleum gas. Therefore, Marin simply let those liquefied petroleum gas as by-products escape into the world.

Smelling the faint smell of LPG in the air, Marin regretted:

"Liquefied gas, a bottle of one hundred and dozens in the previous life, what a waste ..."

However, he did not regret letting these liquefied gases escape. Why? Because the collection of liquefied petroleum gas requires a long pipeline and some special equipment. If the pipeline is short and ignited immediately, the burning of liquefied petroleum gas will go back to the gasoline collection area against the short pipeline and ignite the gasoline. Therefore, under the circumstance of not wanting to be too troublesome, and the output being too small, Marin simply let the liquefied petroleum gas escape outside. At the same time, the gasoline collection container is actually placed outdoors. In this way, the safety of the people in the house can be fully guaranteed. Even if deflagration occurs, it also occurs outdoors. You know, Marin stands in the house and directs the operation. If it really makes an explosion, he will be a traverser, and the book will be over ...

...

Although not a major in chemistry, Marin found a picture of an oil fractionation tower from the memory of middle school chemistry. This is a picture of a normal temperature fractionation tower. In this picture, it is clearly marked that the liquefied petroleum gas is collected at the top of the tower, and the collection temperature of gasoline is at 0140 degrees; paraffin oil is 140 180 degrees; kerosene is 180 250 degrees; diesel It is 250350 degrees; above 350 degrees, it belongs to the heavy oil range. In addition to asphalt, heavy oil can also be used as fuel. For example, warship steam turbine boilers generally burn heavy oil; the lubricating oil is 380,500 degrees ... As for those that do not vaporize above 500 degrees, it is the asphalt of petroleum waste. However, asphalt can also be paved ...

Of course, this is just the schematic diagram of the simplest room temperature fractionation tower. Actual oil refining is very complicated. In addition to atmospheric pressure fractionation, there is also vacuum fractionation. The light gasoline distillate is obtained, it seems that the octane number is not high enough, and catalytic reforming is needed, such as hydrocracking. However, those are too complicated, Marin does not understand, he only knows the process of atmospheric distillation.

Although it is said that the gasoline fractionated by the local method, the octane number may not be high enough. However, Marin does not need too high octane number. Because, he made this elementary earth gasoline, actually in order to carry out a fire attack in the war. If it is a fire attack, this local gasoline is definitely enough ...

...

Moreover, even the simplest atmospheric distillation column, Marin can never get it out. At his middle school chemistry level, it is absolutely impossible to control the temperature of each outlet. There are seven or eight outlets in a tower, and the temperature of each outlet must be controlled within a certain range ... This is too difficult ... But if the temperature is not controlled well, the fractionation tower will be useless. Because if the temperature is deviated, it is easy to cause the mixing of different fractions and then fractionation ...

Moreover, in the low temperature region, the limit of the fractional distillation temperature is also not obvious. For example, light oils up to 170 degrees can be processed through catalytic reforming to become high-octane gasoline. Therefore, the boundaries between gasoline and paraffin oil, and paraffin oil and kerosene seem to be less obvious.

...

So Marin thought about it, and re-refined the remaining oil again. However, this time, the refining temperature was raised to 200 degrees. In order to control the temperature, Malinte uses mercury thermometers to monitor the temperature and avoid excessive temperature.

Why prevent excessive temperature? Because Marin used tin tin ...

The melting point of tin is 231 degrees. If the temperature is too high, the tin tin container will be melted. How about a ghost? If you want to extract oil in a higher temperature range, you must use copper or iron vessels ...

Then, at a high temperature of 200 degrees, Marin made a barrel of mixed oil containing heavy gasoline, paraffin oil and kerosene.

This oil is not as flammable as gasoline, but if mixed with gasoline, the firepower is also very fierce. Anyway, Marin just wanted to burn the wooden gates of Edinburgh, Scotland, and he didn't need the high purity gasoline.

So Marin took out half of this blended oil and mixed it with the previous light gasoline. At the time of mixing, Malinte used the oil in the upper half of the barrel of mixed oil. Because, the lighter the oil will float on the upper layer, the stronger the burning ability. After testing, it was found that it still burned fiercely, which was considered a very powerful fire attack oil.

As for the remaining half of the barrel of mixed oil, it is estimated that most of the kerosene. So, Marin asked the craftsman for help and made a simple kerosene lamp. The wick is a thin double-layer wool cloth, and the oil lamp is also equipped with a **** with a barb for the wick made by the watchmaker. The lamp cap is stuck on a glass bottle, and a simple glass cover is made on it to prevent the kerosene lamp from being blown out by the wind.

Last life ~ www.novelhall.com ~ Marin spent his childhood in the country. At that time, the power supply in the countryside was very unstable and there was always an intermittent power outage. Therefore, kerosene lamps are prepared in rural areas. Therefore, Marin is very familiar with kerosene lamps, and it is also easy to get a kerosene lamp. After all, he has many artisans.

Light gasoline is too volatile, which can easily cause deflagration and is not suitable as a lamp oil. The barrel of mixed oil in Marin Lane has only part of the heavy gasoline that is not volatile, and most of it floats on the upper layer. It is also used to mix the kerosene used for fire attack. The remaining half of the barrel of oil, mostly composed of kerosene and paraffin oil, is very suitable as a lamp oil. The kerosene lamp is much stronger than the popular candles and torches. At least, after adding the lampshade, don't worry about being blown out by the wind or sneezing ...

In addition, in order to further confuse the outside world, Marin decided to add some material to the barrel of semi-mixed gasoline to cover the eyes of others.

As a result, Marin added red pigment to the blended gasoline, making the blended gasoline look as bright as blood. Can you imagine such a red oil material being extracted from black oil?

In addition, Marin also added gelatin boiled with fish skin to make the blended gasoline look very viscous. Red and sticky blended gasoline, if someone without knowledge can guess the origin, it is called a ghost.

Of course, the volatile smell of gasoline may make people notice. So, Marin added some odor-masking condiments to it, making the smell unpleasant. In this way, it is difficult for the average person to smell the gasoline ...

In the end, Marin let people use a speedboat to send one of the semi-mixed gasoline to Newcastle to facilitate the Fourth Army to burn down the gates of Edinburgh. As for the remaining half-barrel, Marin thought about it and decided to take it to Italy to see what opportunities he could use ...
