"Nima?"
After hearing the name of this energy technology, Li Fanyu was stunned.
I learned the technology of biodiesel as early as my freshman year in the experimental class.
This technology is not a new thing. In 1912, Diesel, the founder of the engine, pointed out in a report at the Missouri Engineering Congress that rapeseed oil could be used as fuel for the engine, but this did not seem to make much sense at the time.
However, as global oil resources are increasingly depleted, extracting fuel from biological vegetable fats has become more and more promising.
In the 1980s, the United States first used rapeseed oil methyl ester as engine fuel and burned it for 1,000 hours. After this, renewable fatty acid monoesters were defined as biodiesel.
This technology sounds quite advanced, but in fact the principle is not difficult.
It is a process that uses animal and vegetable fats and methanol or ethanol to react with fatty acids to obtain fatty acid monoalkyl esters. The final thing extracted is fatty acid methyl ester, also known as biodiesel.
Compared with traditional petrochemical diesel, this kind of biodiesel has the characteristics of low sulfur content, low aromatics, high flash point, high cetane number, and good lubricity.
It can be used as fuel as a partial replacement for petrochemical diesel, or it can be mixed and used together with petrochemical diesel.
But...
Although this technology existed in the 1980s, after more than thirty years of scientific research and public relations, the technology for extracting fuel from fat is still incomplete.
The main production method still uses chemical catalysts.
Take the chemical production method that Li Fanyu learned in college;
Mix bio-fat with low-carbon alcohols such as methanol or ethanol, and then use sodium hydroxide or sodium methane accounting for 1% of the weight of the fat as a medium.
Under an acidic or alkaline catalyst and a high temperature of 230-250 degrees Celsius, a lipid exchange reaction occurs to generate fatty acid methyl esters and ethyl esters.
The two substances are then separated, and the fatty acid methyl ester is washed and dried to obtain the finished product.
The entire production process is complex, and the demand for methanol, ethanol, media and catalysts is particularly large.
This means that the cost of this fuel is not low.
In order to fully decompose fat, methanol and ethanol are generally used in excess. Therefore, in the production process of biodiesel, methyl ethanol cannot be completely reacted, and a follow-up process for alcohol recovery is required.
Sounds troublesome, right?
But don’t think that’s the end of it!
Even if these difficulties are overcome, it does not mean that qualified biodiesel can be extracted from animal and vegetable fats.
In the process of chemical production, the water and free fatty acids in the oil raw materials will seriously affect the yield and quality of biodiesel, so the fatty acid methyl esters produced are not very stable.
When the temperature is too high, the fatty acids in fat will become unsaturated. Under such circumstances, biodiesel will also change color and deteriorate...
Product purification is complex, the esterification product is difficult to remove, and the by-products generated by the reaction are difficult to remove. The use of acid-base catalysts will also produce a large amount of wastewater, making this production method particularly serious in secondary pollution to the environment...
So although this technology was developed by scientists and put into production in the mid-1980s, it has never been popularized.
Even in the context of increasing energy depletion, various countries have been vigorously researching this kind of fuel that can replace diesel using rapeseed, soybeans and corn, but they still have not been able to find a particularly good way to produce it. There are revolutionary breakthroughs in the process and extraction methods.
So, when Li Fanyu heard about this familiar technology, he felt like he had been cheated by the system.
Can this broken game be considered a black technology?
The most important thing is it worth 100 million? !
Just when he was about to shout three times to get his money back, the things that had just been forced into his brain by the system began to quickly integrate with his thinking.
As soon as Li Fanyu shouted the word "retreat", an idea suddenly occurred to him, and he frowned and tilted his head.
"Hiss..." He took a breath, "Isn't it right? It seems...that there is another way to extract biodiesel from fat raw materials?"
He shook his head and felt that there seemed to be a little bit of new ideas in his mind about the refining method of biodiesel.
Breakthrough......
But what should we do specifically?
Thinking about it carefully, I feel that I have no clue.
A few scattered chemical formulas came to mind, but they could never form a established chain.
This feeling is like seeing a teacher who seems to have taught you the algebra test during the college entrance examination, but you don't know how to do it.
It looks familiar, but it lacks a breakthrough point and coherent thinking.
That is to say, it lacks the legendary, finishing touch!
This feeling of having a new world at the doorstep was something he hadn't encountered in a long time since he stopped doing advanced math problems.
With this subtle feeling, he slowly crossed his legs and sat on the floor of the laboratory.
What Li Fanyu didn't know was that in his mind, those materials were being combined with his thinking at high speed.
This feeling is like bricks all over the sky dancing wildly out of thin air, building a tall building in no order.
It's also like using breakpoint downloading. The progress bar of downloading a video is intermittently, and you can only watch the wonderful scene for two or three seconds.
In short, I could only get a glimpse, but not the whole thing!
During this process, Li Fanyu felt almost crazy.
Unconsciously, two hours passed quietly.
After some brainstorming, the data that came with the brainwaves has slowly been completely integrated with his thinking.
Suddenly, there seemed to be a soft cry of bili in his mind.
At this moment, it was like a big explosion in the universe, and the consciousness carrying the technology that only living things have has turned into stars, forming a magnificent scene in Li Fanyu's mind!
It's like the download progress of ***** slowly changed from 22% to 100%. The progress bar on the video player instantly turned into a straight line.
Bang!
It was like thunder and fire.
A beautiful body like **** Teacher Ozawa, Teacher Takizawa, and Teacher Tianhai appeared before his eyes!
This moment, in Li Fanyu's mind, seemed to have gone through a long month, or a year.
He frantically absorbed these thoughts and quickly integrated them with his own knowledge.
More than half an hour passed.
Finally, after he trembled all over, he slowly opened his eyes.
"Biodiesel chemical synthesis method... is simply... weak!"
At this time, there are already six ways to extract biodiesel in his mind!
Some of these methods are derived from revolutionary thinking based on the existing scientific research results in this time and space.
Some use methods that do not exist in this time and space. According to the current research and development progress, scientists may not be able to understand it even in another twenty years!
But at this time, Li Fanyu has become clear and clear along the way.
Just pick it up!
