Process for producing high-carbon alcohols from syngas
Thread Content
I would like to ask everyone: Are there any processes and catalysts that use syngas to directly synthesize high-carbon alcohols and have been put into industrial use? Is there a built device in operation? Those who know about it, please share!
Are there any processes and catalysts available for directly synthesizing primary alcohols of C5 and higher using syngas? If anyone knows, please let me know! We urgently need the technological processes in this area! :)

Could you tell me which researcher at the Shanxi Coal Chemistry Institute is responsible for this achievement? Great for looking up relevant information! :)

C5 alcohols can be produced using the formylation carbonylation process, where syngas is just one of the raw materials; a C4 olefin is also required. The formylation reaction first produces C5 aldehydes, which are then converted into C5 alcohols through hydrogenation. Other higher carbon alcohols are similar; of course, condensation and hydrogenation processes can also be used, such as the condensation of C4 aldehydes to form C8 enaldehydes, which are then hydrogenated to yield octanol. For more details, one can search for information on butyl octyl alcohol production techniques and similar topics.
You could look into the Lanzhou Institute of Chemical Physics under the Chinese Academy of Sciences; this institute has a long history in carbonyl synthesis； You could also look into the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences; they are working on this area. For example, Professor Ding Yunjie is also engaged in the heterogeneous transformation of homogeneous catalysts. For catalysts in carbonylation synthesis, the best ones are the homogeneous organic phosphine rhodium catalysts produced by Union Carbon Company. What product market is the poster targeting with high-carbon alcohols? Can we talk?
When synthesizing high-carbon alcohols directly from syngas, the result is a mixture of alcohols, right? At the end of last year, I learned that Yanchang was working on an industrial demonstration facility in collaboration with the Dalian Institute of Chemical Physics. I’m actually a bit skeptical about this; if it’s a mixed alcohol, will the cost remain competitive after adding a separation process? Moreover, I understand that this technology produces normal aliphatic high-carbon alcohols, whereas the high-carbon alcohols used in the plasticizer industry are all isomeric
Okay, I see; it means there are still economic issues with this production process.
This is just my personal question; to find out the actual situation, it’s necessary to ask Teacher Ding or Yanchang Petroleum
