Methanol production from carbon dioxide

Bro, did you make a mistake? Are you talking about adding CO2 to methanol synthesis gas? I’ve never heard that CO2 can be used to produce methanol.

Yes, we are currently conducting research in this area. However, the investment required might be substantial. If possible, carbon dioxide could be utilized to help reduce greenhouse gas emissions.

Are you researching biological methods? Is the catalytic method suitable for using CO2 in lighting? Hydrogen addition is necessary after all – where does the hydrogen come from?

The guy on the first floor – this research topic is really great; it’s very significant for reducing CO2 emissions. This is more suitable for plants with excess hydrogen feedstock in the production process. Of course, by utilizing biological hydrogen production and solar hydrogen production, and combining them in this project, everyone gets what they need. :handshake :handshake :handshake :victory: :victory: :victory: :hug: :hug: :hug:

If it’s truly possible to produce methanol from CO2, that would bring great benefits to industries and the environment worldwide. I believe that as the chemical industry declines, biocatalytic technologies will gradually take center stage!

This topic is excellent; I give it my full support. Once the research is completed, coal will no longer be wasted. Keep up the good work!

The idea is quite new, but implementing it in practice is rather difficult. :)

Thank you all. Our company is also researching electrochemical-assisted biological hydrogen production and solar electrolysis for hydrogen production, and using the hydrogen produced to synthesize methanol and other substances.

The topic on the first floor is great. In fact, a company from Mitsubishi in Japan has made substantial progress in the development of methanol production from CO2, and we in this country should catch up.

Traditional CO2 methanol production involves the use of a large amount of H2, which is why it is tried to be avoided as much as possible! Actually, the conversion rate is quite high too!

It’s not that CO2 cannot be used to produce methanol; in fact, among the various ways of utilizing CO2, producing methanol is one of the simpler methods. Of course, there are also current studies on using CO2 to produce hydrocarbons, namely gasoline or diesel fractions. However, everyone here has a background in chemistry and chemical engineering, so they are naturally familiar with the concepts of enthalpy and Gibbs free energy. So I would like to ask everyone here a question: for simple carbon-based energy sources (including coal, oil, and natural gas, which account for the vast majority of carbon-based energy sources), what is the lowest form of energy that exists in nature? ? If CO2 is converted into other usable forms of energy, such as methanol, how much energy do we need to consume in this process to produce methanol? Where does this part of the energy come from? Therefore, in my personal opinion, if biological or solar energy is not used in the process of converting CO2 into other usable forms of energy, then there is simply no need to conduct such research. No matter how good the catalysts may be, they cannot change the initial and final thermodynamic states; in other words, they cannot alter the fact that CO2 is the ultimate form in which carbon-based fuels can be utilized. Since the ultimate form of carbon-based energy consumption is CO2, what kind of process is it to convert CO2 back again? ? ? All day long, there’s talk about the greenhouse effect, about alternative energy sources, and about the fact that coal shouldn’t be used, since it is also a non-renewable resource (of course, under the current natural conditions, it indeed cannot be renewed). That’s all correct, what you said is right, but I have a question in return: is there anyone who knows something about statistics on energy use? From a statistical perspective, what proportion do non-carbon-based energy sources account for in the overall energy consumption structure? Therefore, I believe the more practical question is what utilization methods yield the highest energy efficiency; in other words, high-efficiency methods should be chosen as much as possible during production and utilization. At present, among various utilization methods, diesel engines seem to have relatively high efficiency, so it is reasonable to increase the use of diesel engines. During the growth process, or rather the conversion process, there are usually several pathways: 1, direct combustion for power generation ； 2. Produce methanol, and then use it to manufacture downstream products. (Incidentally, the price of methanol in China is now unbelievably low; yet people still keep investing heavily in its production. What’s the point of that?) Prices are influenced by supply and demand, which is a very basic principle. At the same time, the development of methanol gasoline is being restricted, and the most common argument against it is that methanol is highly toxic. Then everyone comes up with such reasons; just because you say it, it becomes truth. How sad. Let me ask a question in return: Everyone has probably heard of hydrogen fuel cells, which are said to be the energy source for cars in the future. So, what is used to produce hydrogen? The currently popular approach is to produce hydrogen from methanol. There is a talented person in China who specializes in this area of research; he won some prestigious award in the UK and has done very well in his work. He graduated from East China University of Science and Technology and is now in Oxford; I have a classmate who is working there right now. Such an amazing future energy source, and yet it still requires methanol to be added to vehicles. That’s why I fainted! ! ! So, regarding methanol gasoline, can reasonable industry standards be established? ? ? If there’s time, let’s start a separate thread for everyone to discuss it). 3. Coal to oil, using indirect or direct liquefaction. Wait. Which of these approaches results in a higher capacity utilization? Are there any experts or specialists who have conducted comprehensive analyses and comparisons of these various utilization methods? I’ve always wanted to work on this, and I’ve had this idea for a long time; however, my position prevents me from carrying out such work, as I don’t have access to sufficient data, which makes it impossible to conduct accurate comparisons. Those who are interested, let’s communicate and even work together!

It is indeed very meaningful; it can reduce the greenhouse effect and is beneficial to environmental protection. More environmental protection technologies should be developed in the country.
