In a chemical reaction device that improves a 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, the cumulative value being obtained by cumulatively adding, from one end to the other end of a cooling surface in a height direction, products of (i) a distance L between (a) a surface of a catalyst layer which surface is in contact with a transmission wall and (b) an outer surface of the cooling surface and (ii) a height H of the catalyst layer corresponding to the outer surface having the distance L.

Chemical reaction method, chemical reaction apparatus and production method

A source material gas () is supplied to a catalyst (), a first heating medium () is caused to flow through a first heat exchange section () so that a temperature of a surface of the first heat exchange section () on a catalyst side is maintained higher than a dew point of a reacted gas (), a second heating medium () is caused to flow through a second heat exchange section () so that a temperature of a surface of the second heat exchange section () on a space () side 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.

Chemistry reaction method and chemistry reaction device

A gas separation apparatus includes a separation membrane module including at least one gas separation membrane element in a housing, a casing for blocking external air, and a heat source unit for adjusting a temperature of a heat medium with which the casing is filled. The casing holds greater than or equal to two separation membrane modules.

Gas separation apparatus and gas separation method

Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.

Gas separation method

Provided is a method for separating a specific gas from a raw gas using a gas separation membrane module that includes a gas separation membrane element enclosed in a housing. The element includes a gas separation membrane including a hydrophilic resin composition layer. The method includes: preparing the module; increasing pressure in an interior of the module; increasing a temperature in the interior; and feeding a raw gas to the interior. The layer of the module prepared is adjusted to contain moisture, and a moisture content thereof is an amount that allows an equilibrium relative humidity at a temperature of 23&#xb0; C. of a gas phase portion in the housing to be 10% RH or more. The raw gas feeding step is performed after the preparation step. The pressure increase step and the temperature increase step are performed after the preparation step and before the raw gas feeding step.

Provided is a facilitated COtransport membrane having improved COpermeance and improved COselective permeability. The facilitated COtransport membrane includes a separation-functional membrane comprising a hydrophilic polymer gel membrane which contains a COcarrier and a COhydration catalyst, wherein the hydrophilic polymer is a copolymer including a first structural unit derived from an acrylic acid cesium salt or an acrylic acid rubidium salt and a second structural unit derived from vinyl alcohol. More preferably, the COhydration catalyst has catalytic activity at a temperature of 100&#xb0; C. or higher.
