Abstract
Provided is a method for efficiently producing propylene from propanol containing a large amount of water. A method for producing propylene includes a dehydration reaction step of dehydrating a raw material containing propanol and water using a catalyst containing silica-alumina, the silica-alumina having a SiO2 content of 3 to 80 in terms of a molar ratio with respect to Al2O3. The catalyst containing the silica-alumina is produced by a method including a step of carrying out calcination at a calcination temperature of not lower than 400° C. and not higher than 950° C.
Claims6
A method for producing propylene, the method comprising a dehydration reaction step of dehydrating a raw material containing propanol and water with use of a catalyst containing silica-alumina, the silica-alumina having a SiO2 content of 3 to 80 in terms of a molar ratio with respect to Al2O3, wherein the catalyst containing the silica-alumina is produced by a sol-gel or impregnation production method including a step of carrying out calcination at a calcination temperature of not lower than 400° C. and not higher than 950° C.
