Dehydrogenation of isopropanol to propylene
Thread Content
Are there still devices for producing propylene through the dehydrogenation of isopropanol in chemical plants today? I have to work on this for my graduation project this year, but it seems that such devices have been phased out according to the literature I’ve reviewed????
It has no economic value at the moment; the prices of the two are reversed. Who would go to the trouble of using expensive raw materials to produce something cheap?
Propane is in excess; isopropyl alcohol is more than 1,000 yuan more expensive than propane, so who would use isopropyl alcohol for the dehydration to produce propane?
Currently, there is basically no production of propylene via isopropanol dehydrogenation; propylene is produced as a by-product of phenol production. Moreover, the consumption ratio between phenol and propylene is unbalanced, resulting in an excess of propylene.
