Method for producing epsilon-caprolactam by introducing cyclohexanone oxime gas into a fluidized catalyst layer through holes of 3mm diameter or smaller of a gas diffusion plate |
摘要 |
epsilon -Caprolactam is produced by the method comprising the step of introducing a gas comprising cyclohexanone oxime into a layer of solid catalyst particles through a plurality of holes of a gas diffusion plate so that the solid catalyst particles are brought into contact with the gas, while fluidizing the catalyst layer, characterized in that the holes have an average diameter of about 3 mm or smaller. In accordance with the production method, epsilon -caprolactam can be produced from a raw material gas comprising cyclohexanone oxime with a high conversion of cyclohexanone oxime and a high selectivity to epsilon -caprolactam. |
