Abstract: 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.

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.

Abstract: To enable highly efficient production of an olefin with a low environmental impact. The production includes a thermal cracking step of thermal cracking plastic to obtain a thermally cracked gas (G1) and a catalytic cracking step of cracking the thermally cracked gas (G1) in the presence of a catalyst to obtain a catalytically cracked gas (G2). When a ratio of an olefin to paraffin in the thermally cracked gas (G1) is indicated as R1 and a ratio of an olefin to paraffin in the catalytically cracked gas (G2) is indicated as R2, the following formula is satisfied: R2/R1 > 1.
