Abstract:
Provided is a gas separation membrane having superior gas permeability, separation selectivity and mechanical properties. A gas separation membrane to separate at least one acid gas from a mix gas, comprising in this order: a first layer that is porous; a second layer that is a separation-active layer containing a compound having a molecular weight of 150,000 or less and capable of interacting with the acid gas; and a third layer having high gas permeability.
