摘要： The present invention provides a method for selectively separating a straight-chain conjugated diene with high purity from a mixture containing the straight-chain conjugated diene and at least one type of straight-chain olefin. The method involves separating the straight-chain conjugated diene from the mixture containing the straight-chain conjugated diene and the straight-chain olefin using a zeolite membrane composite. The composite contains a porous support and a zeolite layer formed on the surface and in the fine pores of the support, and the zeolite contains an alkali metal cation.
