Chapter 92: He comes up with three technical solutions like this with just a wave of his hand?! This
Lin Yu nodded and stood up as Chief Hou had instructed.
He closed his notebook, walked to the blackboard, and picked up the chalk.
"Esteemed seniors, there are two main reasons why I've called you all here today."
"First, there are other options besides ethanol gasoline for unleaded gasoline. We can't put all our eggs in one basket."
Nowadays, the commonly used 90, 93, and 97 octane gasoline are all leaded gasoline.
The numbers 90, 93, and 97 represent the octane rating of gasoline. The higher the octane rating, the less likely the gasoline is to knock in the cylinder.
If tetraethyl lead is not used to increase the octane rating, these gasolines will easily become low-quality 70-octane gasoline.
In later generations, the commonly used gasoline types were 92, 95, and 98.
Some gasoline has an octane rating that reaches this value.
Some of them reach this octane rating after the addition of ethanol.
In regions like the three northeastern provinces and parts of North and East China, where ethanol gasoline is being promoted, gas stations only offer ethanol gasoline.
The gasoline grades are specifically marked as E92-E95-E98.
However, this does not mean that pure gasoline with a high octane rating cannot be produced.
He wrote a few words on the blackboard:
Methanol gasoline, alkylated oil, and ether additives.
"Let's talk about methanol gasoline first."
Lin Yu turned around and glanced at the Sinopec team present.
"Methanol can be extracted from coal, and our country has abundant coal resources, which is a huge advantage."
"Methanol can be blended into gasoline to increase the octane rating, and the cost is lower than that of ethanol."
"Our country is rich in coal, poor in oil, and lacks gas. This plan is just the right thing for us to improve the utilization rate of oil."
Upon hearing this, Chief Engineer Chen of Sinopec paused for a moment, then instinctively spoke:
"Methanol? That stuff is so corrosive, can the engine withstand it?"
Lin Yu nodded; he had only understood this by borrowing knowledge from later generations.
"Mr. Chen is right, that's why we need additives."
"I added a small amount of corrosion inhibitor to the formula, the main components of which are benzotriazole and modified fatty acids, which can effectively protect engine parts."
He picked up the chalk and wrote a series of chemical formulas on the blackboard.
"This is the basic blend: M15 gasoline, 15% methanol, 85% gasoline, with an octane rating of over 93. The carbon monoxide and hydrocarbon emissions in the exhaust are reduced by 30% compared to regular gasoline."
The meeting room was filled with the sounds of flipping through notebooks and whispering.
They thought the plan was pretty good, since thermal power generation alone wouldn't be enough to use up all the coal mined each year.
Before they could think it over, Lin Yu proposed a second solution.
"The second option is alkylated oil."
Lin Yu continued writing:
"This stuff is made from refinery byproducts, isobutane and butene. These two substances can react to produce alkylated oil under the action of an acidic catalyst."
"The main component is isooctane, with an octane rating as high as 94-97. It contains almost no olefins or aromatics and burns very cleanly."
"The advantage of this solution is that there are almost no pollutants in the exhaust gas, and the United States has been using this as high-octane aviation gasoline since the 30s."
"They were using it during World War II."
"Domestic production conditions are not yet available, but I have proposed a solid acid process that can be tested by the Sinopec team."
These words caused an uproar. This stuff wasn't exactly top secret; many industry experts knew that the United States was currently using this kind of oil.
Chief Li, who is more knowledgeable in the industry, knows that this stuff is a hard currency in fighter jet refueling.
The current Su-27 fighter jet is hampered by the Russian-made TS-1 fuel system, which is constrained by its use of specially formulated gasoline.
The cost is 2.3 times higher than that of jet fuel 2, and the fuel cost of the Su-27 formation is more than five times that of the J-7.
Thinking that if this stuff really was the same as that alkylated oil from the Americans, he would make a fortune, and then he couldn't help but interject:
"Is this thing expensive to produce?"
Lin Yu shook his head.
"It's slightly more expensive than ethanol gasoline, but it has two advantages: first, it can utilize existing byproducts from refineries, turning waste into treasure; second, it can be used as a blending component for high-end gasoline, improving the overall quality of the fuel."
He paused, then added:
"More importantly, the production process of alkylation oil can itself absorb some of the waste gas from refineries, reducing environmental pollution."
"It can make the sky cleaner."
This pleased Chief Li greatly, as he knew that alkylated oils from the United States were exactly like this.
He assumed that this was what Lin Yu meant by fighter jet fuel, and after hearing it, he leaned back in his chair, completely satisfied.
If it weren't for respect for Lin Yu, I would have wanted the formula to try synthesizing it in the factory right now.
This is awesome! With this, fighter jets can perform missions in more extreme environments.
Seeing that Chief Hou was satisfied, Chief Li secretly chuckled to himself, thinking that Chief Li was unaware of Lin Yu's tactics.
The truly good things are always revealed last.
Although he was also shocked that Lin Yu could produce alkylated oil, but...
This wasn't the thing Lin Yu recommended when he went to see him in the afternoon!
Lin Yu's introduction was far from over; he turned around and wrote another line on the blackboard:
MTBE – Methyl tert-butyl ether
"The third option is ether additives."
"This is even simpler. Methanol reacts with isobutylene to produce MTBE, which can also increase the octane rating when added to gasoline, and it is also very miscible with gasoline."
"It contains no lead, no sulfur, and no aromatics. When mixed with gasoline, it can directly turn low-octane gasoline into high-octane gasoline."
"Production is much safer than alkylation oil, and the barrier to entry is much lower."
"It is neither highly toxic with hydrofluoric acid nor corrosive with concentrated sulfuric acid."
"Small investment, quick results, and rapid domestic production. It can be built, put into production, and profitable all in one year."
"Personally, I recommend alkylated oils as the flagship product in the high-end market, and MTBE as the main product for mass production."
随后林宇详解了一下生产过程，从1.05~1.1：1的配比，到反应时50~70℃和0.8-1.2Mpa的大气压。
These are all conditions that are very easy to achieve. That's how organic chemistry works; once a suitable production method is found, it's very easy to replicate.
The difficulty lies in finding it, but ironically, finding this condition has become a hurdle that traps many people.
Chief Engineer Chen's eyes lit up as he listened, convinced that the entire process could be quickly replicated. He couldn't help but slam his hand on the table and shout "Applause!"
"Great! If these plans can all be implemented, we'll have no shortage of unleaded gasoline!"
Lin Yu nodded and put down the chalk.
"So what I'm trying to say is that unleaded gasoline is not a single technological approach, but a cluster of technologies."
"Ethanol, methanol, alkylated oil, and MTBE each have their own advantages, and we can tailor our approach to local conditions and specific factory needs."
After saying that, he returned to his seat and took a sip of water.
Give everyone time to process this.
The meeting room was silent for a few seconds, then a low murmur arose.
They really made the right choice coming here; they never expected Lin Yu to be so formidable.
If we include ethanol gasoline, there are four such plans.
The industry that had trapped them crumbled before Lin Yu's eyes.
This kid's genius is outrageous!
Commander Hou flicked his cigarette ash and said with a smile:
"Alright, these plans should keep you digesting them for a while. Lin Yu, let's talk about the second thing."
Lin Yu put down his water glass, stood up, and this time when he walked to the blackboard, his expression became more serious.
"The second thing is for our military."
Chief Li of the Equipment Department sat up straight instantly, his mind filled with questions.
Wasn't it alkylated oil that they gave to the military?
This stuff surprised and delighted him immensely; it was a super high-end aviation fuel additive!
If these aren't the main points, then what else is for the military?!
