Habit, maybe the big rivers in future generations won’t be so yellow?

Looking at the row of several bamboo tubes in front of him, Fei Qian felt a little emotional, "You can get something like this by boiling it with stone lacquer. If it is not good enough, it will cause fire, burn and destroy it. I don't know how many times..."

Engaging in scientific research is really not an easy task.

Although Fei Qian had learned about distillation technology in his junior high school chemistry class, and even knew that petroleum, gasoline, kerosene, asphalt, etc. are the products of aromatic hydrocarbons with different boiling points produced through distillation, but Fei Qian could not remember how to do it specifically.

Yes. The junior high school chemistry textbook simply drew an equal sign and noted the word distillation. However, when it comes to actual practice, it contains too many things and many unknowns.

Huang Yueying almost burned down the Hussar's backyard...

"Huh? Shi Yuan is not allowed...it cannot be eaten..." Fei Qian saw that Pang Tong seemed to subconsciously put some oil to his mouth, and quickly stopped him. Fei Qian did not want to name this oil "Luo Feng Oil"

.

Fortunately, Pang Tong only wanted to try the clear oil, and was not interested in the thick and pungent black oil.

Pang Tong put down the bamboo tube in his hand, then pointed to the other one and said: "The smell of this oil is okay...but there is a bit of a stench inside this tube..."

Fei Qian nodded and said: "These four kinds of oils are all made from stone paint. They are slightly different and have different uses."

Due to limitations of conditions and materials, Fei Qian could not carry out precise fractionation and refining of oil like later generations, but could only roughly separate it to produce four different oils.

One very important thing is that Feiqian has separated grease that can be used as lubricating oil. After separating the clear oil that is easier to burn, the grease separated again will be relatively viscous. Although it can also be used for burning,

But it is not flammable, so it can completely replace the original lubrication effect of plant and animal oils.

Previously, all of Feiqian's lubricants and weapon maintenance oils used animal fats, mainly cattle and sheep fats. Later, pig fats were added. However, most people in the Han Dynasty did not have enough meat to eat.

Using animal fats for lubrication of utensils and maintenance of weapons is undoubtedly a relatively luxurious thing.

Now, lubricating oil refined from petroleum has replaced animal oil, so the saved animal oil can be consumed by more Han people to improve their physical quality.

Moreover, this kind of lubricating oil can be widely used in various machinery, including but not limited to workshop hydraulic equipment, various vehicle bearings and other mechanical load-bearing gears.

Of course, this also includes ballistae.

There are also steering bearings on four-wheel vehicles.

China has not developed four-wheeled carriages before. There are many reasons, but the most important point is that they are not needed. Two-wheeled carriages are already sufficient, so there is no need for further improvement.

However, Feiqian is different now. When the Western Region is opened up, a large number of carrying vehicles must be transported back and forth. However, relying solely on camels, horses and other animal power is undoubtedly insufficient. Four-wheeled vehicles with stronger and greater carrying capacity will become

It is an important starting point to solve traffic problems.

Another important oil is the extraction of the clear oil that Pang Tong wanted to taste.

Very easy to burn and light in weight.

Fei Qian thinks it should be similar to the one between kerosene and gasoline in later generations. It is lighter than the originally used fire oil, which means it can be used with trebuchets to produce an effect similar to gasoline bombs...

This is a very terrible weapon for attacking large-scale targets, especially sieges.

Pang Tong looked at it, then pinched the sparse beard on his fleshy chin and said, "My Lord, can this thing conquer the Western Regions?"

Fei Qian nodded and said, "A certain person has been sent directly to Yumen, and he will be able to reach the Western Regions in the near future. The foreign countries have built strong cities in the Western Regions, and a strong attack will surely cause many losses. This is the right time." Moreover, there is also oil in the Western Regions.
