Method for producing epsi-caprolactam and reactor for the method |
摘要 |
A method is provided for producing epsi-caprolactam from cyclohexanone oxime by using a zeolite or non-zeolitic material as a catalyst under gas phase reaction conditions. The method comprises a reaction step converting cyclohexanone oxime into epsi-caprolactam in the presence of the zeolite or non-zeolitic material; and a regeneration step of treating the zeolite or non-zeolitic material with a non-oxidizing gas at a temperature of from about 100°C. to about 600° C.
