Abstract: In a chemical reaction device (100) that improves an yield of a product and that causes a reaction, progress of which in a gaseous phase is restricted by a chemical equilibrium between a source material and the product, a cumulative value is not less than 500 mm 2 , the cumulative value being obtained by cumulatively adding, from one end to the other end of a cooling surface (53) in a height direction, products of (i) a distance L between (a) a surface of a catalyst layer (3) which surface is in contact with a transmission wall (40) and (b) an outer surface of the cooling surface (53) and (ii) a height H of the catalyst layer (3) corresponding to the outer surface having the distance L.

Abstract: The present specification discloses a method of producing a concentrated carbonate aqueous solution. The present invention relates to a method for producing a concentrated carbonate aqueous solution, comprising a step of dewatering a hydrogen carbonate aqueous solution by means of a salt blocking membrane to prepare a concentrated hydrogen carbonate aqueous solution, wherein the concentrated hydrogen carbonate aqueous solution obtained in the above step is heated to thermally decompose the hydrogen carbonate into carbonate, carbon dioxide and water, and to evaporate water to obtain a concentrate of the carbonate aqueous solution.

Abstract: This method includes a gas acquisition step (S1) of obtaining a gas containing a carbon oxide and hydrogen from a waste material from which methanol is to be produced and a conversion step (S6) of bringing at least a portion of the gas into contact with a catalyst to convert the portion of the gas into methanol in a gas phase, in which, in the conversion step (S6), the reaction is allowed to proceed by condensing a high-boiling-point component containing methanol obtained as the result of the conversion and water and then discharging the condensed product to the outside of a reaction system.

Abstract: A source material gas (31) is supplied to a catalyst (30), a first heating medium (21) is caused to flow through a first heat exchange section (22) so that a temperature of a surface of the first heat exchange section (22) on a catalyst side is maintained higher than a dew point of a reacted gas (32), a second heating medium (51) is caused to flow through a second heat exchange section (52) so that a temperature of a surface of the second heat exchange section (52) on a space (4) side is maintained not higher than the dew point of the reacted gas (32), and a liquid obtained by condensation in the space (4) is allowed to fall down so as to be separated from the source material gas.
