In fact, car owners in China are generally worried because of the news of rising oil prices, especially those middle-class people who choose to change oil to gas or buy gas cars directly after careful calculation.

The sales volume of gas vehicles in China increased significantly in July this year. Dongfeng Motor, the first to eat crabs, got the biggest piece of cake.
Stimulated by this incident, the gas car projects of major car companies in China are also enthusiastic.
Chapter three hundred Hidden dangers
Shenhua Tuan
The large-scale coalification base of Baotou branch of the company welcomed a group of guests.
This coalification base is currently in the trial operation stage, and it can produce 50,000 tons of polyolefin every year.
Shenhua Group is one of the few coal groups in China with a set of coal chemical technology. Besides Baotou Branch, there are also four coal chemical bases.
Li, manager of Baotou Coal Chemical Base, took Chen Biting, chairman of Shenhua Group, and the coal chemical research team of the scientific research department of Suiren Company.
Ying hua zhao, the chief researcher of the research team, looked at these large reactors and equipment and discussed them with team engineers and researchers from time to time.
Engineers from Shenhua Group also participated in the discussion.
Ying hua zhao looked up and asked, "How much coal tar does Manager Li have in the factory at present?"
Hearing this question, Li replied without thinking, "At present, the international crude oil price of about 327 yuan per barrel is profitable."
Ying hua zhao shook his head unceremoniously. "It’s too high. Once the international crude oil price drops to 5 meters per barrel, your project will be profitable."
"There is no way to do this. After all, the production is there." Li is also very resistant
Shenhua people certainly know the fatal disadvantage of coalified oil, that is, the production is too high. Once the international oil price falls, the whole project will be profitable.
At present, they need to consume 13 tons of fresh water, 55 tons of coal, depreciation of equipment and average labor achievement of 327 RMB per barrel for refining a ton of coal oil.
Looking through it for a while, ying hua zhao found the reason why Baotou coalification oil was too high
The so-called connection method of Baotou coal gasification oil process is to gasify coal into water gas (namely carbon monoxide and hydrogen) and then synthesize fuel oil and other products
In this production process, the average 4 yuan of 55 tons of coal needs 22 yuan to calculate each ton.
Coalification oil 55 tons of coal = 1 ton of fuel oil
But the calorific value is 142 tons of standard coal = 1 ton of crude oil.
That is to say, theoretically speaking, 142 tons of standard coal = 1 ton of crude oil is the maximum conversion efficiency of coal chemical industry.
Ying hua zhao turned around and said, "Your catalyst can’t work. Change our company’s nitrogen 16! In my laboratory, our company’s nitrogen 16 catalyst averages 17 tons of coal to make 1 ton of fuel. "
Shenhua engineer in charge of coal gasification oil technology is also very surprised. If the coal gasification efficiency is calculated according to this formula, the coal content in coal gasification oil will drop from 22 yuan to 6 yuan per ton.
Ying hua zhao once again pointed out a problem: "Another point is that one ton of catalyst can produce 5 tons of fuel oil, and one ton of catalyst can produce hundreds of thousands of tons of fuel oil."
Ma Guosheng, the chief engineer of the project, was very embarrassed by ying hua zhao, as if Shenhua’s coal chemical technology was really worthless in front of people.
"And nitrogen 16 catalyst gasification, impurities, environmental protection are higher than your old catalyst …"
After some calculations, they found that the comprehensive cost of coalified oil was actually reduced to 727 yuan per ton, that is, about 1 yuan per barrel, which is equivalent to about 16 meters per barrel of fuel oil.
Chen Biting, the chairman of Shenhua Group, listened with hot eyes.
Like a barrage, ying hua zhao didn’t stop, but said quietly, "You can also benefit those poor coals and coal gangue to further reduce the raw materials into a lot of profitable elements in the refined waste residue. If these things are fully utilized, the comprehensive benefits of the factory will rise very much."
Ma Guosheng, who was embarrassed, humbly consulted while taking notes.
Chen Biting asked with some impatience, "Researcher Zhao should also be able to increase the production capacity of the new technology?"
"well! The coal gasification process can increase the efficiency by 32 times, but the gasification oil process needs you to reinvent it to bring out the efficiency by 32 times. "ying hua zhao nodded.
Chen Biting and several Shenhua engineers discussed for a while that the capacity of 60,000-70,000 tons of coalification oil can be formed after upgrading the capacity of the current five coalification bases of Shenhua Group.
However, there are still many unfinished projects in the former country. These projects can initially form a production capacity of 1 ~ 120,000 tons.
It is possible to form 30,000 tons of production capacity in one year and increase it to 60,000 tons in two years.
In addition, Shenhua Group can also explode coal chemical industry in addition to coal chemical oil industry.
