Chemistry reaction method and chemistry reaction device

A chemical reaction device which causes a reaction to proceed, a product of the reaction containing a component having a boiling point higher than that of a source material gas, progress of the reaction in a gaseous phase being restricted by a chemical equilibrium between a source material and the product,

• the chemical reaction device comprising:
• a catalyst to which the source material gas is supplied and which promotes the reaction;
• a transmission wall which allows a reacted gas produced by the reaction to pass therethrough;
• a first heat exchange section positioned on an opposite side from the transmission wall with respect to the catalyst interposed between the first heat exchange section and the transmission wall;
• and
• a second heat exchange section spaced apart via a space from the transmission wall,
• a first heating medium being caused to flow through the first heat exchange section so that a temperature of a surface of the first heat exchange section which surface is in contact with the catalyst is maintained higher than a dew point of the reacted gas;
• a second heating medium being caused to flow through the second heat exchange section so that a temperature of a surface of the second heat exchange section on a side of the space is maintained not higher than the dew point of the reacted gas;
• and
• a liquid obtained by condensation in the space is allowed to fall down so as to be separated from the source material gas.

A chemical reaction device, comprising

• a reaction container including at least one reaction tube that has a multiple structure and that causes a reaction to proceed inside the at least one reaction tube, a product of the reaction containing a component having a boiling point higher than that of a source material gas, progress of the reaction in a gaseous phase being restricted by a chemical equilibrium between a source material and the product,
• each of the at least one reaction tube including:
• an inner cylinder which allows a reacted gas produced by the reaction to pass therethrough;
• an outer cylinder which is included in a first heat exchange section and inside which the inner cylinder is provided;
• and
• a second heat exchange section which is provided inside the inner cylinder,
• the source material gas being supplied to a catalyst layer provided between the inner cylinder and the outer cylinder,
• a second heating medium being caused to flow through the second heat exchange section so that a temperature of an outer surface of the second heat exchange section is maintained not higher than a dew point of the reacted gas,
• a liquid obtained by condensation in a first space formed between the second heat exchange section and the inner cylinder being allowed to fall down so as to be separated from the source material gas,
• a first heating medium being caused to flow on an outer side of the outer cylinder so that a temperature of an inner surface of the outer cylinder is maintained higher than the dew point of the reacted gas.
