Weekly topic: Which products can be produced more profitably using water-coal slurry pressurized gasification technology?

I searched on Baidu; it should be synthetic ammonia

Now: Polyurethane Future: Methanol gasoline

It’s hard to say! Just like now, there are many plants that produce methanol, which has led to an excess supply of methanol and a drop in its price. But currently, gasification products are being used to produce methanol, which is then used to make dimethyl ether! It should be fine! In the future, this product has great potential for use in gasoline! It’s hard to say; it depends on the technology!

I design refining units; producing hydrogen using POX is highly profitable, with costs of 0.8 yuan per standard cubic meter, while the market price can reach around 1.5 yuan!

There are many products that can be produced from the syngas obtained through the pressurized gasification of water-coal slurry; it mainly depends on the current process technologies and product markets. The methanol process is the most mature, but the current methanol market is poor with an oversupply; using methanol to produce olefins might yield better results, though the investment costs and profits have not been calculated yet. As a raw material for ammonia synthesis, its production process is well-established, but it requires significant investment; it is not something that small-scale enterprises can afford to undertake ； Dimethyl ether can be directly synthesized using syngas, but this is only possible if there is a market for the dimethyl ether or a project for its reuse ； Syngas can be used to produce methanol, polyoxymethylene, and other products, as well as additives for petroleum products. Syngas can be used to directly produce ethylene glycol; this process is fairly mature, with industrial pilot tests already completed. It was developed by East China University of Science and Technology, and it features good energy consumption and product yield, so industrial scale-up of this process deserves special attention.

Please introduce the pressurized gasification technology for water-coal slurry, as well as the process used for synthesizing polyurethane; let’s learn from each other*

Another use for methanol is in methanol-based gasoline, such as M5, M15, M35, M50, M80, M100； There are many grades, named according to the different levels of methanol incorporation. For methanol gasoline of grades M15 and below, car engines can be used as is without any modifications; during the blending process, M5 can be blended directly without the need for solvents. I’m not sure if everyone is optimistic about the future market for methanol gasoline, or what the prospects for this fuel will be in the future. Please share your own opinions and exchange ideas with one another. If methanol-blended gasoline is to be introduced on a large scale in the market in the future, using syngas to produce methanol represents a good option, and this will also bring new opportunities to China’s methanol industry.

At the moment, butyl acetate and olefins are better; it’s hard to say what will be the case in the future.

This also needs to be closely related to the market. Simply producing methanol won’t be profitable at all unless it is done in areas with available resources – near coal deposits. Currently, the markets for methanol-based olefins, polyurethanes, butyl octanol, etc., are still good. What about from now on? It is also closely related to oil prices and market saturation.
