Title:
REACTION DEVICE, AND METHOD FOR PRODUCING ε-CAPROLACTAM
Document Type and Number:
WIPO Patent Application WO/2013/105343
Kind Code:
A1
Abstract:
The present invention pertains to a reaction device containing: a fluidized bed type reactor for chemically reacting a starting gas in the presence of a solid catalyst; a fluidized bed type reproducer for reproducing a portion of the solid catalyst, of which the catalyst activity has declined due to being used in the reactor, such that the catalyst activity is recovered by heating the solid catalyst in an oxygen-containing gas atmosphere; and a pressure control unit for controlling the pressure within the reactor and/or the pressure within the reproducer such that the pressure within the reproducer becomes greater than the pressure within the reactor. According to the present invention, a reaction device capable of preventing rapid oxidation or a combustion reaction caused by mixing the reaction gas in the reactor and the reproduction gas in the reproducer is provided.
