What are the main current disadvantages of coal-to-oil technology?

1# actwang has high energy consumption, its technology is not yet mature, and further product development is needed! In short, continuous improvement is needed in coal-to-oil and oil shale refining; there is no absolute best solution, only ongoing refinement

It has high energy consumption, high water usage, high CO2 emissions, and a low energy conversion efficiency; personally, I think IGCC combined with chemical co-production is a better option

Carbon dioxide sequestration isn’t something that can be done just by finding any place and starting the process. The appropriate site for storage must be determined based on the geological structure. The view advocated by Shanglou Xianh walnut regarding IGCC is quite reasonable. Yet, it is regrettable that China faces difficulties in developing IGCC technology. It has been 29 years since the concept of IGCC was first proposed in China; over these 29 years, has anything been accomplished?

Hehe, actually, there are IGCC power plants right next to the direct liquefaction facilities for Shenhua coal

Coal-to-oil: Shenhua’s technology is not yet sufficient. Yankuang’s is the real standard.

Coal-to-oil production can make use of excess methanol exhaust gases, turning waste into a valuable resource; the profits can be substantial. However, the high temperatures and pressures involved make it very dangerous.

There are several issues that need to be addressed in coal-to-oil conversion: economic problems, which are greatly influenced by the petrochemical industry. Converting one form of energy into another obviously involves energy consumption during the conversion process. The economic aspects of energy utilization need to be considered. Next are technical issues: with the rapid development of indirect liquefied gas gasification technologies, efficient and stable gasification techniques are a problem that cannot be ignored. Engineering issues of indirect liquefaction Fischer-Tropsch synthesis technology. There are also issues related to **policies and energy strategies.

The energy consumption is relatively high, mainly reflected in aspects such as water, electricity, gas, and air. Additionally, the requirements for equipment are high, resulting in significant losses.

Sun certainly dares to speak out openly; he’s not someone who avoids meeting people. It’s true that he has connections with SASOL, and it’s also true that Yankuang’s technology originated from SASOL. Yet it was no easy task for him alone to develop Yankuang to its current level within just a few years. After all, Yankuang only acquired one person from SASOL, not an entire department, so many things had to be established from scratch by Yankuang itself. Shenhua’s direct liquefaction technology was indeed developed by them themselves, but it would be a lie to say that it has no connection to foreign technologies; as for indirect liquefaction, it certainly isn’t their own technology – it belongs to the Coal Chemistry Institute. So there’s nothing special about such things; what’s the point for the Chinese to fight among themselves to the point of suffering heavy losses? Engage in internal strife – if you have the capability, then compete with advanced foreign technologies. I’m just wondering why Yankuang’s project wasn’t approved.

How can you tell from my post that I am Sun’s spokesperson? I would like to, but they don’t necessarily need me. I’m not qualified enough to be the spokesperson for Sun; you have more experience, so could you please help me get an introduction? There are many things that others may not be unaware of; I certainly don’t dream about them every day – money and beautiful women aren’t even enough to fill my dreams. I’ve heard something about the matter you mentioned, but your conclusion is that Sun didn’t attend the meeting in order to avoid SASOL’s people, and as a result one of his subordinates ended up making a fool of himself under SASOL’s pressure. I assume you also attended that meeting, so how do you know for sure that Sun didn’t go there just because of SASOL? Is that just your speculation? Or just rumors heard? Or are you the legendary spokesperson for Sun? Sun might not want to communicate with SASOL’s people, but so what? What does that tell us? It simply shows that they have disagreements and differences of opinion; in more serious cases, they may even go to court. It’s like a married couple who get divorced and stop communicating with each other for the rest of their lives. But that doesn’t mean Sun can’t be seen in public or leave his home. By your logic, there must be many people in China who share Sun’s situation. How much of China’s technology is actually based on ideas borrowed from others? If you look down on Mr. Sun, there’s no need to rush into betting with me. You could have a debate with him – maybe he’ll avoid you out of fear. But if you’re willing, I can act as a go-between for you. Would you be so kind as to consider it?
