Methods of methanol production
Thread Content
Recently, I came across a method for synthesizing methanol in the book \"The Methanol Economy\". This method involves using hydrogen produced by electrolyzing water – and electrolysis can be powered by various types of energy sources, including alternative non-mineral energy sources and nuclear energy – to chemically convert the hydrogen in the air into methanol. In this way, humans can produce methanol through the chemical recycling of carbon dioxide from the air, whereas carbon dioxide and water are abundant resources on Earth. Considering the use of hydrogen in fuel cells, that is, the chemical conversion processes such as carbon dioxide + electrolyzed water (hydrogen) = methanol, and methanol + water = hydrogen + carbon dioxide, what would be the cost of hydrogen? What are the economic advantages of using electrolyzed water (hydrogen) directly + compressed transportation?
This mainly depends on energy consumption and cost-effectiveness. A craft that does not generate profit can only be considered theoretical research.
It’s feasible to use it in the military industry, in places where money is not a constraint.
There are no industrialized or commercialized solutions; generally, you won’t get satisfactory answers in HaiChuan
Thank you! There are still many great gods in Kaichuan, and they’re worth looking forward to!
The cost of directly electrolyzing water is very high; I’m not sure how to calculate it
Three issues need to be addressed: 1. The cost of hydrogen production. At present, it is mainly electricity costs; solar or nuclear fusion power generation can be considered only if it becomes efficient in the future. 2. The issue of CO2 purification. The cost from the air is too high; flue gas can be considered. 3. The efficiency of synthetic catalysts: currently, the efficiency for CO2 is significantly lower than that for CO
