Title:
GASEOUS PRODUCT ACQUISITION APPARATUS AND GASEOUS PRODUCT ACQUISITION METHOD
Document Type and Number:
Japanese Patent JP2021120147
Kind Code:
A
Abstract:
To provide a gaseous product acquisition apparatus in which distribution of temperature in a reaction tube can be controlled to be uniform in a prescribed range and defect relating to hot spot can be prevented, and a gaseous product acquisition method.SOLUTION: A gaseous product acquisition apparatus is provided, comprising: a reaction tube 12 having a reaction tube inner cavity 23 for communicating a gas inflow port with a gas outflow port; an external heat transfer medium tube 13a having an external heat transfer medium tube inner cavity 24a for communicating an external heat transfer medium inflow port 16a with an external heat transfer medium outflow port 17a; and an internal heat transfer medium tube 13b having an internal heat transfer medium tube inner cavity 24b for communicating an internal heat transfer medium inflow port with an internal heat transfer medium outflow port. A catalyst is placed in the reaction tube inner cavity 23, a gaseous raw material 8 is brought into contact with the catalyst to cause chemical reaction, a heat transfer medium 19 in the external heat transfer medium tube inner cavity 24a performs heat exchange with a heat transfer medium in the reaction tube inner cavity 23 through a reaction tube wall, a heat transfer medium in the internal heat transfer medium tube inner cavity 24b performs heat exchange with a heat transfer medium in the reaction tube inner cavity 23 through an internal heat transfer medium tube wall. A gaseous product acquisition method is also provided.SELECTED DRAWING: Figure 3
