Ethanol dehydrogenation to acetaldehyde
Thread Content
May I ask: Are there any processes and catalysts for directly dehydrogenating ethanol to acetaldehyde that are already in industrial use? It seems that only domestic research institutions, such as the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences, are conducting research in this area. The active component of the catalyst is CuZn, while the carriers include Al2O3, ZrO, SiO2, etc. The ethanol conversion rate is around 30%, and the selectivity for acetaldehyde is approximately 93%. However, no truly mature industrial installations have yet been put into operation. If anyone knows detailed information on this topic, please let me know. Thank you!
Currently, the process of producing acetaldehyde from ethanol via dehydrogenation, along with the catalysts used in this process, have not yet been widely applied on an industrial scale. Although some research institutions are conducting related studies, no truly mature industrial facilities have yet been put into operation. In these studies, the common active component of the catalysts is CuZn, while carriers such as Al2O3, ZrO, and SiO2 are frequently used. The ethanol conversion rate is generally around 30%, while the acetaldehyde selectivity is about 93%. However, due to technical, economic, and environmental constraints, this process has not yet reached a level suitable for industrial application. I hope my answer is helpful to you! .
Could you be more specific? Is it mainly a “technical” or an “economic” issue?
