Wizard: I crush the legend with my martial arts

Chapter 95 Making Activated Carbon

As soon as he returned to the castle, Alphonse called the soldiers guarding the gate and asked them to find mud and stones to build three simple stoves, two high and one low.

At this moment, Medio's fire ring technique came in handy.

The moist soil quickly becomes dry and solid.

Then I brought some charcoal, smashed it into pieces, cleaned it briefly, and stuffed it into the jar.

The simplest way to make activated carbon is to inject superheated steam into hot charcoal to activate it.

Ordinary water vapor is composed of condensed small water droplets and water vapor. Under standard atmospheric pressure, the temperature will not exceed 100 degrees, which is relatively mild, so it is called saturated steam.

But if the water vapor is continued to be heated on the steam pipe, the water vapor inside will be completely vaporized, and the temperature will exceed 100 degrees. The greater the steam pressure, the higher the temperature.

The steam at this point becomes extremely destructive.

That is superheated steam.

Although it is still water in nature, it can be easily ignited.

If there is a source of fire, it will ignite as soon as you spray it.

When everything was ready, Alphonse filled the large kettle half a man's height with water and placed it on the low stove.

The large iron can filled with charcoal was placed on the stove at the other end and fixed with iron branches.

Iron branches are also readily available. Taixi had the blacksmith shop cast them for barbecue, so there is no need to look for them separately.

After confirming that the spout of the big kettle was securely connected to the iron can, Alphonse asked Medio to light the stove for boiling water.

The level of his fireball technique is not high, and it is quite convenient to use it to ignite fire if you control the power.

Hilde watched with interest and had no intention of going to the castle to accept the reception.

He is already here, and his two guardian knights and Master and Servant Posec can only wait obediently.

Although Hilde was sweating profusely, she didn't need to take a shower.

He casually cast a cleaning technique, and the clothes and body around him were clean again.

This made Alphonse very enthusiastic.

This magic is indeed very convenient. It can keep your body clean even in harsh environments where you cannot take a bath.

Otherwise, how can we say that being a Buddhist priest is an elegant profession?

According to him, the mage who originally created this magic came up with the magic of Cleansing because he was obsessed with research and didn't want to waste time taking a bath.

High-level cleaning techniques can not only clean clothes and bodies, but also purify some abnormal conditions.

Disease is a different matter, it requires the Sickness Technique, which is an intermediate magic that neither Hilde nor Medio knows yet.

When the water in the big kettle was about to boil, Alphonse immediately asked Medio to light the other two stoves, fill them with firewood, and let the flames burn high.

Three stoves heat together at the same time.

Soon, hot steam spurted out from the hole in the bottom of the big iron can.

According to the video I watched on Xiaopo.com, the entire heating process should not be less than an hour.

I can only wait patiently.

"What's the point of doing this?" Hilde couldn't restrain her curiosity and asked doubtfully.

"This is to turn charcoal into activated carbon. There are actually many pores on the charcoal that are invisible to the naked eye. When hot water vapor blows through, it can produce an activation effect, which can effectively absorb various substances and pigments. It can also be used Come and purify the water." Alphonse answered casually.

"Purifying water? Activated carbon?" As an alchemist, Hilde knew that charcoal could filter impurities, but the method of spraying the charcoal with steam and then refining it was unheard of.

Activated carbon is also a term he has never heard of.

"You'll see the effect later." Alphonse smiled.

In modern times, knowledge that any high school student can understand is revealed for the first time in this world. In modern times, making activated carbon doesn’t need to be so troublesome. Put the charcoal into a pressure cooker filled with sodium carbonate solution, boil it at high temperature, rinse it with 80-degree hot water several times, and dry it to get activated carbon.

Of course, there is a simpler way, buy two kilograms on Taobao or Pinxixi.

"How did you know this method?" Hilde still couldn't help being curious, looking like he was breaking the casserole to get to the bottom of it.

"Then we have to talk about a magical bard named Edson." Alphonse started to lie again.

Anyway, for all the things that are difficult to explain, Adelson, who doesn't even exist in this other world, can take the blame.

I guess Teacher Chen won't mind either.

Hilde believed everything without any doubt.

An hour was not long, it passed quickly.

Activated carbon production is completed.

But Hilde didn't care that the iron pot was hot and used the magic hand.

A large translucent hand appeared out of thin air, took down the iron can, and opened the lid.

But he looked left and right and couldn't see any difference between the charcoal chips in the iron can and the original ones.

Alphonse also discovered a problem at this time. There were not enough sugar cubes in the castle for experiments.

Candy cubes are considered expensive items in this world.

Grocery stores in the Cold Wind Territory would not sell this kind of stuff, and civilians couldn't afford candy bars.

You can only go to the city to purchase.

For this matter, just send a few soldiers there, which will just allow them to purchase another batch of Seagram grass.

It never hurts to have more of a good thing like refining incense.

Now the soldiers in the military camp are using it for cultivation, and it consumes a lot of money.

Hilde does not need to be involved in making white sugar.

You don’t have to worry about the production methods being leaked.

Alphonse just made an excuse and made his own activated carbon to filter some impurities in the solution.

Of course, we still need to demonstrate the effect of activated carbon to Hilde to clear up his doubts.

The object of the experiment is very simple. I find a water cup, pick up the soil, throw it in, stir it up, and there it is.

Add activated carbon and let it settle for a while.

He found another cup and slowly poured the water out.

Hilde was shocked to see that the originally turbid muddy water became clear again after being filtered by activated carbon.

Not only does it not contain any impurities, it is also completely the same as before, without any other colors being stained. The effect is surprisingly good.

"Although it has been filtered, the water still needs to be boiled before drinking." Alphonse explained casually.

Alphonse didn't care, but this was a big discovery for Hilde. When his teacher made the potion, in order to filter out the impurities of herbs and minerals, he had to filter it repeatedly. With activated carbon, this should be able to save the time. A lot of trouble.

"Do you mind if I tell others how to make activated charcoal? This activated charcoal is very important to me!" Hilde stared at Alphonse and asked sincerely.

"It doesn't matter, you have seen the production process." Alphonse replied with a smile, and now he just wanted to send Hilde back quickly.

Hilde nodded, "The value of this activated charcoal cannot be measured in terms of money. It will greatly promote alchemy. I owe you a favor!"
