Method for producing acrylonitrile |
| abstract |
The invention relates to a method for producing acrylonitrile which includes a vapor phase catalytic ammoxidation process of performing vapor phase catalytic ammoxidation by bringing a source gas containing propylene, molecular oxygen, and ammonia into contact with a fluidized bed catalyst to obtain acrylonitrile. The method is characterized in that the fluidized bed catalyst is a catalyst containing molybdenum and bismuth and the vapor phase catalytic ammoxidation process is performed while maintaining an adsorbed amount of ammonia per specific surface area (m 2 /g) of the fluidized bed catalyst in the range of 0.05 to 0.6 μmol/m 2 . According to the method for producing acrylonitrile of the invention, it is possible to stably maintain a high acrylonitrile yield over a long period of time. |
